Abstract:
In this study, the lightning protection system and grounding system of one plant of the petrochemical industry were investigated, evaluated, and improved. The methods used in this study were rolling sphere and angle protection methods. The grounding system of the building under study was modeled and simulated using ATP/EMTP (Alternative Transient Program/Electromagnetic Transient Program) software. The results show that the external lightning protection system of the prilling tower studied does not adhere to IEC 62305 and IEC 1024-1-1 standards. Moreover, the grounding configuration of the DCS building was not appropriate for protecting sensitive equipment inside. Lightning causes an enormous potential difference between lightning ground rods in the grounding system. Additionally, disabling the existing surge protective device (SPD) causes an increase in the magnitude of Ground Potential Rise at the DCS building. Improvement of the lightning protection system of the prilling tower and DCS building on Plant 1 of this petrochemical company as well as some other recommendations for improvements are proposed. This paper also shows evidence that external lightning protection, internal lightning protection, and the grounding system need to be connected to make an exemplary lightning protection system.

Abstract:
Anti-lightning strike protection for composite structures is catching great attention to design optimum lightning protection solution. Based on lightning direct effect, optimizations of flame spraying aluminum thickness and composite laminate plies were conducted by combining electrical-thermal analysis procedure and corresponding optimization programs. Optimized thickness was acquired for flame spraying aluminum layer. Meanwhile, non-uniform thick plies and optimized stacking angles were given for anti-lightning strike composite laminate. Comparisons were conducted to investigate changes of lightning direct effects on composite laminates fore and after optimization. Synergetic protections of flame spraying aluminum and laminate plies design were listed. The conclusions can be used as suggestions for lightning strike protection of advanced aircraft.

Abstract:
Abstract According to field operation records, lightning stroke accounts for 60% of transmission line failures. Therefore, it is of great significance to strengthen lightning protection of the power system. However, there are several lightning faults, and the corresponding protection methods differ. Consequently, identifying lightning stroke faults will be beneficial to take corresponding lightning protection measures. This paper investigates the mechanism of different lightning strike faults, and simulates them by a 110kV transmission line EMTP-ATP model. Analysis and simulation show that the direction of tower current represents lightning’s polarity; the insulator voltage’s direction differs when shielding failure or back striking occurs. If insulator flashovers, the voltage of the insulator drops down to zero, and as the transient process comes to an end, the voltage of the insulator on the nearby tower decreases to zero as well; after the occurrence of back striking flashover, the direction of insulator voltage on nearby tower alters. Based on those features, insulator voltage and tower current are introduced as a characteristic signal, and their direction and rms of them are formed as recognition parameters for lightning stroke identification. The EMTP-ATP simulations demonstrate that the proposed method is correct and effective, and the recognition rate of different lightning faults is 100% under the abovementioned method.

Abstract:
In this paper the lightning discharge channel is modeled as a vertical monopole antenna excited by a pulse generator at its base. The lightning electromagnetic field of a nearby lightning discharge in the case of lightning protection using four vertical lightning protection rods was determined in the frequency domain. Unknown current distributions were determined by numerical solving of a system of integral equations of two potentials using the Point Matching Method and polynomial approximation of the current distributions. The influence of the real ground, treated as homogeneous loss half-space of known electrical parameters, expressed through a Sommerfeld integral kernel, was modeled using a new Two-image approximation which gives good results in both near and far fields.

Abstract:
The article points out the drawback of all the current instructions for the lightning protection device: the lack of instructions for calculating the lightning protection zones of an object located on a slope. The methods of applying the current instructions for the lightning protection device when placing an object on a slope are given, based on the assumption that lightning strikes the lightning rods vertically and perpendicular to the slope. The features of the choice of lightning protection characteristics (calculated points of the protected object, calculated heights of lightning rods, methods of constructing lightning protection zones) are described. A method for calculating the lightning protection zones of an object located on a slope is proposed, based on the assumption that lightning strikes lightning rods perpendicular to the slope, in particular, the concept of the axis of a conditional lightning rod shifted on the object plan for calculating lightning protection zones is introduced. The consequences of the application in engineering practice of the methodology for calculating the lightning protection zones of an object located on a slope, based on the assumption that lightning strikes the lightning rods perpendicular to the slope, are indicated. Using a pulse voltage generator, tests were performed on a model of a lightning rod located on a slope in order to determine the direction of lightning strikes-vertical or perpendicular to the slope. It was determined experimentally that the proposed method for calculating the lightning protection zones of an object located on a slope, based on the assumption that lightning strikes lightning rods perpendicular to the slope, should be used in cases where the protected objects are located on slopes with an angle of more than 25°.

The phenomenon of lightning is one of the main threats that can damage buildings and cause material losses and loss of human life. Residential houses are one type of building that is vulnerable to the impact of lightning. Therefore, designing an effective and efficient lightning rod is very important to protect residential houses and their occupants. This research aims to analyze individual knowledge related to lightning rods by looking at existing literature reviews, as well as providing information about the types of lightning rods that exist and how to use them. Later this research can make it easier to design a lightning rod system that is suitable for residential houses by considering the safety and comfort of the occupants. In this research, we conducted a survey and analysis of scientific articles, books, and other reliable sources relevant to individual knowledge about lightning rods. This research will include an understanding of the working principle of lightning, risk assessment of residential houses, selection of the right type of lightning rod, and selection of suitable materials for lightning rod systems. The research method used is interviews with residential homeowners. This interview was conducted to obtain information regarding their experience and knowledge about lightning rods. Based on the results of interviews with residential homeowners who do not install lightning rods, it can be concluded that an effective lightning rod must consider factors such as the specific needs of the residence, environmental characteristics, and local weather conditions.

Abstract:
This study shows how a lightning protection layer can be designed to effectively mitigate lightning damage in underlying composite structures. A parametric study was performed to characterize critical lightning protection layer properties that improve composite lightning damage resistance. Simulated 50 kA and 200 kA lightning strikes to pitch-based carbon fiber paper (PCFP)-protected AS4/3506 carbon/epoxy composites were considered in this study. The lightning protection characteristics of various PCFP outer layers were assessed by varying in-plane and through-thickness properties: electrical and thermal conductivities, and electrical and thermal gap conductances. The predicted matrix decomposition in the outermost AS4/3506 ply was significantly reduced by increasing the PCFP in-plane electrical conductivity. While predicted lightning damage decreased slightly with a decrease in thermal gap conductance, varying the electrical gap conductance and the in-plane and through-thickness thermal conductivities did not significantly affect the damage development. Among various PCFP properties, the PCFP in-plane electrical conductivity was the most critical factor in reducing thermal damage development (thus, protecting the underlying AS4/3506 laminate). This parametric study demonstrates that it may be possible to tailor lightweight non-metallic lightning protection layers as an effective alternative to traditional metallic projection layers.

Abstract:
This article presents a five-year performance review of an early streamer emission (ESE) air terminal lightning protection system for a large scale PV power plant in Thailand. The comparison effect of a Franklin lightning protection system and the ESE lightning protection system was analyzed for the PV power plant. The ESE lightning protection system was selected to be implemented in the PV power plant. The capacity of the PV power plant studied was 8 MWp on an area of 150,000 square meters in the Nong Ya Plong district, Phetchaburi province, Western Thailand. A Franklin lightning rod type was also designed to be implemented in this PV power plant. The Franklin lightning rod type comprised 122 pieces but the ESE lightning rod type consisted of only 11 pieces. The conceptual design of the Franklin rod type followed the standard of the Council of Engineers, Thailand, and the ESE lightning rod type followed the NFC17102 standard of France. The estimated cost of installation was a key comparison to select the lightning protection system; the total installation cost of the Franklin lightning rod type was USD 197,363.80 and the ESE lightning rod type was USD 44,338.06. The lightning system was applied to the lightning arrester in the power plant to provide good protection, in which the balance of the pole to the mounting position is required to optimize the system performance. The result of the simulation also showed that the shading effects of the Franklin rod type were greater than the ESE rod type. The installation cost of the Franklin lightning rod type was 4.45 times more expensive than the ESE lightning rod type. Therefore, the ESE lightning protection system was selected to be implemented in the PV power plant. From the recorded data of the five-year performance of the ESE lightning protection system (2016–2020), there were three occurrences of a lightning strike on the PV power plant. The ESE lightning protection system effectively protected and prevented the lightning strike to the PV power plant. This study can help and support with the selection of a lightning system for the protection of large scale PV power plants in the future.

However, this technique would have some defects. In order to improve the predicting accuracy of the lightning striking of tall buildings, there are three methods, i.e. a broken line method, the method of Faraday cage, and ball method. The electrical geometry model of rolling ball method as the theoretical basis for calculating is easy. In order to analyze lightning striking selectivity of buildings, the shielding between buildings were discussed based on the electric geometric model (ball method). It is different lightning probability for different monomer buildings, building groups, different distance, different geographical environment, and climate environment. And some protection measurements were proposed to improve the lightning shielding performances.

Abstract:
Lightning is a weather-related phenomenon with dire consequences for tall structures. The lightning protection adopted in Sri Lanka in stupas in ancient times, from the third century was adequate, as no lightning damage to stupas have been recorded in early times However, the present restoration of lightning protection may be inadequate as recent strikes have been detected due to improper new practices due to an absence of detailed recording of the lightning protection in ancient times. This paper discusses the lightning protection of stupas, especially of Ruwanweliseya from ancient times to the present, tracing the history of lightning protection from the Mahawansa and the Culawamsa. While the bulk of the lightning energy probably went through the stupa in ancient times, the modern protection tends to bring the energy to earth through the surface of the stupa and the compound at the bottom which can cause disastrous effects. Monitoring is recommended to be undertaken to see whether the dissipation of bulk of the lightning energy is through the stupa itself, even in the present day, or along the surface of the stupa and through the compound at the bottom.

Abstract In order to avoid the harm caused by the direct effect of lightning, modern new ships are equipped with lightning direct effect protection devices. However, due to the harsh environment such as high temperature, high humidity and high salt, it is easy to change its performance indicators and affect the lightning protection effect. Taking the direct lightning protection device with gaps installed at the rear end of the ship antenna as an example, through the study of its working principle and main technical indicators, the items that need to be tested regularly are determined, and the corresponding test methods are formulated. Through a large number of experiments and test data verification, the conclusion that the method can effectively reflect the main technical indicators of lightning protection facilities and then effectively evaluate the protection effect of lightning protection facilities is drawn. The research results of this paper are of great significance to regularly test the lightning direct effect protection equipment, accurately grasp the changes of its technical performance indicators, and ensure the protection effect of lightning direct effect.

Abstract:
This study evaluated lightning protective system efficacy on 11kV-132kV substation-power line installation in Ikorodu, Lagos State, Nigeria with reference to cloud to ground(C-G) lightning strike (LS) events. It focus on interception of lightning strikes and its protection with reference to direct lightning strike (DLS) and indirect lightning strike (IDLS). Data were collected from Ikorodu 132/33 kV Transmission Substation and its four major injection stations. This work was carried out using physical measurement of raw data obtained from the high voltage substation. Installations were scaled down and modelled dimensionally using AutoCAD software in order to measure spatial parameters in order to measure the screening of the existing substations and connected lines, as well as the existing cone angles of protection. Probability of lightning efficiency of lightning protective level (LPL) are used for screening evaluation while spike and sky wire angle of protection are used for cone of protection evaluation. Physical measurement of six substations (33/11 kV and 132/33 kV substations) in the studied area were also carried out to evaluate the effectiveness of the installed lightning arresters with respect to the protected devices using applicable standard. The results under the prevailing lightning protective system, LPS, (screening method), revealed that the existing 33/11 kV and 132/33 kV substations are not adequately protected against lightning strike; 132/33 kV substation is more vulnerable to lightning strike than 33/11kV substation and that the incoming 132kV power lines to the substation are adequately protected. The evaluation of the installed distances of all lightning arresters are within standard range and would adequately protect substation transformers against travelling waves (Indirect Stroke) events. The installed lightning arresters (LAs) would adequately protect substation transformers against travelling waves (Indirect Stroke) events. The adequate protection should be reinforced with proposed design scheme in further study in order to mitigate the disastrous effects of lightning strike. Any proposed design of protective system for electric power installations in Nigeria should be simulated using computer aided design software for scaled validation of dimensional and spatial design values in order to mitigate reported failures and uncertainties in identifying causes of observed failures in the system.

Abstract:
It is well known that lightning strokes produce mal-operation of transmission line protection relays. Where, protection devices cannot identify correctly between lightning stroke that generates or not permanent faults. Thus, when a flash produces a permanent fault, the protection relay sends a trip order, and the Transmission Line (TL) is disconnected correctly. However, when a lightning stroke does not produce a permanent fault, the protection devices also send the trip order, and the TL is disconnected unnecessary. In this context, these phenomena can produce unnecessary electric power outages, producing damage for the society and economic. Therefore, it is necessary to correctly identify between these lightning stroke signals. Besides that, direct lightning strokes, which hit directly on TLs or transmission towers, have usually been analyzed. However, induced lightning strokes, which hit on ground, have not been considered in previous analyzed. In this paper, in order to identify these induced lightning strokes, an algorithm based on a deterministic focus is proposed.

Abstract:
Abstract Lightning safety in private and public buildings is a seriously evaluated issue that requires an appropriate and safe long-term solution to protect property from destruction during or due to the consequences of a lightning strike. Relatively easy-to-replace home appliances such as a TV-set or a vacuum cleaner, larger and more expensive appliances such as a heat pump, alarm system or antennas can be damaged from a lightning strike. The aim of the study is to explore the ways of lightning protection in buildings and to develop recommendations for its effective use. Lightning protection is part of a set of electrical assembly and fire protection measures of property, which are performed during construction or renovation of property and the installation thereof is determined by the regulatory framework of the Republic of Latvia. Over time, two types of lightning protection systems have been developed: the classic or passive lightning protection system, which, if hit by lightning, captures and drains the electrical charge generated by lightning to the ground, and the active lightning protection system, which attracts the electricity generated by lightning with energy generated by itself and then drains the charge to the ground. Consequently, both lightning protection systems can be considered to have their advantages and disadvantages, so it is necessary to assess the choice of the most appropriate protection system on a case-by-case basis, also taking into account the criteria such as the complexity of the building project, the size and accessibility of the protected area and the cost of each individual site.

In this research the evaluation method is carried out using data collection and data analysis methods. Data collection methods consist of, observation, measurement, literature study, and Interview. Data analysis consists of, Building needs for lightning protection, Determining protection, Distribution conductors, and Grounding. The evaluation results show that, based on the index stated in the standard (SNI 037014.1-2004) the Main Power House building really needs a lightning protection system. Based on the estimated danger of lightning strikes with a risk level of R=14 (highly recommended), the use of conventional lightning rods with the protection angle method still requires increased protection in the form of the addition of 5 air terminations (splitzers) on the right, left, front, side and back. and the distribution conductor and earth termination (grounding) for both lightning rods as a whole meet the standards.

Abstract The critical point of lightning protection of the 10 kV distribution network is lightning-induced overvoltage protection. The traditional lightning protection measures cannot solve the problem for the 10 kV Distribution Network. This paper developed a distribution network lightning-induced overvoltage suppression device. The device comprises core inductance, nonlinear resistance, and a parallel adjustable gap. The device operates in three states according to the lightning overvoltage amplitude. The lightning energy is discharged through the device to the earth. The lightning-induced overvoltage amplitude is reduced to below 75 kV. The device’s effectiveness is verified by theoretical analysis and simulation in MATLAB/SIMULINK. The device has significant advantages, such as good lightning protection affection, minor disturbance to the distribution network, and light installation work volume.

A new technology of initiative protection for lightning stroke based on electric field cancellation theory is presented in this paper. The real time lightning detection system and the active protection equipment are adopted. By using this new method, the protection technology of direct lightning stroke can be changed from little current triggering to weakening the electric field near the weapon system, and the down leader of charged thundercloud can be repulsed by the artificial opposed field. So the lightning discharge condition in this protection region can be destructed, and the lightning hazard to the protected equipment is eliminated radically. It effectively reduces the electromagnetic radiation, ground potential reaction and step voltage caused by the high current along conducting wire in the conventional lightning rod protection technology.

With the advancement of meteorology modernization, automatic weather station had become an important means of atmospheric sounding. Collecting data and information security were basic requirements for meteorological monitoring and forecasting. When lightning struck large scale and very large scale integrated circuits, the automatic station can be damaged or its data collector can be interrupted. Two-level SPD lightning protection system and three-level ferrite lightning protection system can compensate for the lack of lightning protection board and power protector. MATLAB simulation analysis shows that the three level lightning protection circuits with ferrite are better than the two level SPD circuits in guaranteeing the automatic station operation. Putting the ferrite rings around the power lines or communication lines, along with the common lightning protection devices, can make the load terminal voltage limit to 500V. The lightning current is significantly reduced by using the simple method in the collector.

Abstract:
When a direct strike occurs, the lightning surge current will intrude into the steel frame and steel bar of the building, forming a high lightning electromagnetic environment inside the building, which will affect the telecommunications equipment set in the building. Therefore, the problem of lightning protection in buildings becomes more and more important. In this paper, by studying the distribution law of lightning electromagnetic field in buildings, the intensity of magnetic field generated in buildings under different lightning strikes is analyzed. According to the three-dimensional diagram and equivalent diagram of the intensity of lightning magnetic field in each case, when the building encounters direct lightning, the lightning electromagnetic field is the strongest near the leadoff line, and the middle zone is weak. The lightning protection measures inside the building are put forward.
