Abstract:

Based on data from PLN, in 2020 the number of PLN customers has reached 77,19 million or increase of 3.59 million customers compared to 2019 which amounted to 73,6 million customers. Along with modernization in Indonesia, without realizing it there is still a lot of wasted electrical energy from electronic devices that are left on standby and not used or electric vampires. The purpose of this research created a tool to overcome the problem of electric vampires in electronic equipment in order to reduce the number of losses below the national electric losses of 8%. The implementation method used for the design and manufacture of the Electric Vampire Remover is the Research and Development (R&D) research method. The steps taken are: 1) analysis of tool requirements, 2) design of tool, 3) manufacture of tool in the laboratory, 4) testing of tool functions and performance, 5) concluding the results. These stages are conducted in cycles to get the best result. The result of the research is the creation of an Electric Vampire Remover which is functionally proven to be able to control electrical equipment properly. This tool can be operated stand-alone or based on internet network. The results showed that the tool was able to reduce losses caused by electric vampires by 99%. The application of this tool at home is able to save 36,908 kWh which is equivalent to Rp. 53,320.99/month in the fare class or R-1/1300 VA power.

Abstract:

In the transition to a circular focus on electric and electronic products, manufacturers play a key role as the originators of both the products and the information about the products. While the waste electric and electronic equipment (WEEE) directive’s contemporary focus is on handling the product as waste after its end of life, the circular economy focuses on retaining the product’s value with a restorative system. The polluter-pays principle requires producers of pollution to bear the costs of handling the pollution, leading to the extended producer responsibility (EPR) principle. This requires manufacturers to change their focus from their current passive role of out-sourcing end-of-life treatment to taking explicit responsibility for product management over an extended period of time. This paper investigates how a manufacturer can assume its responsibility to achieve circularity for its products. Based on our findings, three fundamental circularity principles, the circular electric and electronic equipment (CEEE) principles, for manufactures of electronic and electrical equipment are defined: (1) Serialize product identifiers, (2) data controlled by their authoritative source at the edge, and (3) independent actors’ access to edge data via a distributer ledger are the foundation of the Edge and Distributed Ledger (Edge&DL) model. We demonstrate the model through a case study of how to achieve circularity for lighting equipment. The CEEE principles and the demonstrated model contribute to building new circularity systems for electronic and electric products that let manufacturers undertake their extended product responsibility.

Abstract:

Purpose – The purpose of this paper is to analyze the recent global situation on waste of electric and electronic equipment (WEEE) management and recommend policy directions for designing environmental strategies. Design/methodology/approach – Qualitative research approach is adopted to review studies on WEEE management in developed and developing countries. The focus is to critically consider the available options for its safe management. Findings – Approximately 40-50 million tons of WEEE is generated worldwide annually and most of it is dumped in the developing countries. WEEE is not a challenge to be faced by a single country as it has trans-boundary effects and ultimately the contamination reaches back to the developed countries with a lapse of time. Research limitations/implications – Data availability on WEEE generation and disposal is in initial stages. Practical implications – Developing countries in Asia and Africa do not have resources to handle WEEE. The unregulated and unsafe WEEE management practices in these countries let hazardous materials to disseminate into the marine life and global ecosystem. Originality/value – The paper recommends policy directions to deal with the emerging issue that may have globally far reaching consequences.

Abstract:

Considering that the large quantity of waste electrical and electronic equipment plastics generated annually causes increasing environmental concerns for their recycling and also for preserving of raw material resources, decreasing of energy consumption, or saving the virgin materials used, the present challenge is considered to be the recovery of individual polymers from waste electrical and electronic equipment. This study aims to provide an update of the main identification methods of waste electrical and electronic equipment such as spectroscopic fingerprinting, thermal study, and sample techniques (like identification code and burning test), and the characteristic values in the case of the different analyses of the polymers commonly used in electrical and electronic equipment. Additionally, the quality of the identification is very important, as, depending on this, new materials with suitable properties can be obtained to be used in different industrial applications. The latest research in the field demonstrated that a complete characterization of individual WEEE (Waste Electric and Electronic Equipment) components is important to obtain information on the chemical and physical properties compared to the original polymers and their compounds. The future directions are heading towards reducing the costs by recycling single polymer plastic waste fractions that can replace virgin plastic at a ratio of almost 1:1.

Abstract:

Filter capacitors play a critical role in ensuring the quality and reliability of electrical and electronic equipment. Aluminum electrolytic capacitors are the most commonly used but are the largest filtering components, limiting device miniaturization. The high areal and volumetric capacitance of electric double-layer capacitors should make them ideal miniaturized filter capacitors, but they are hindered by their slow frequency responses. We report the development of interconnected and structurally integrated carbon tube grid–based electric double-layer capacitors with high areal capacitance and rapid frequency response. These capacitors exhibit excellent line filtering of 120-hertz voltage signal and volumetric advantages under low-voltage operations for digital circuits, portable electronics, and electrical appliances. These findings provide a sound technological basis for developing electric double-layer capacitors for miniaturizing filter and power devices.

Abstract:

This study addresses a sensitive topic, namely how human subjects undergoing medical procedures can be protected by means of medical electrical equipment. A solution to this problem is to monitor the stabilized electrical supply voltages of the medical equipment. The net effect of the proposed protection is the automatic disconnection of the medical equipment from the alternating voltage network supplying the medical equipment. This disconnection must be done without using electrical switching devices that contain electrical contacts that can generate electrical sparks. This is because most of the time the medical equipment is placed in an area where pure oxygen or other combustible gases predominate. Therefore, only static relays are used in this case. The realized electronic module has been tested in the laboratory and is capable of automatic disconnection of any medical equipment from the 230 V~, f = 50 Hz AC power supply in the case of major faults, which can be caused by accidental overvoltage on the electric energy supply lines, accidental overtemperatures, transient overvoltage which are propagated during storms, etc. This study presents the transient phenomena that occur in the immediate vicinity of the monitored voltages range. Finally, a solution for simultaneous monitoring of four electric voltages and/or currents is presented.

Abstract:

During the last few decades, the poor quality of produced electric power is a key factor that has affected the operation of critical electrical infrastructure such as high-voltage equipment. This type of equipment exhibits multiple different failures, which originate from the poor electric power quality. This phenomenon is basically due to the utilization of high-frequency switching devices that operate over modern electrical generation systems, such as PV inverters. The conduction of significant values of electric currents at high frequencies in the range of 2 to 150 kHz can be destructive for electrical and electronic equipment and should be measured. However, the measuring devices that have the ability of analyzing a signal in the frequency domain present the ability of analyzing up to 2.5 kHz–3 kHz, which are frequencies too low in comparison to the high switching frequencies that inverters, for example, work. Electric currents at 16 kHz were successfully measured on an 8 kWp roof PV generator. This paper presents a fast-developed modern measuring system, using a field programmable gate array, aiming to detect electric currents at high frequencies, with a capability for working up to 150 kHz. The system was tested in the laboratory, and the results are satisfactory.

Abstract:

The problems of reactive power compensation and improving the quality of electrical energy in the power supply systems of industrial enterprises are inseparable. Their relevance is due to the widespread use of electric receivers that consume reactive power and distort the quality of electrical energy in the network, as well as the implementation of new technologies, systems and equipment into production that make increased demands on the quality of electrical energy consumed. An important characteristic of the quality of electrical energy rationed by GOST 32144–2013 is the non-sinusoidal voltage. The main reason for the non-sinusoidal voltage in the electrical networks of industrial enterprises is the use of electrical equipment with a nonlinear voltage characteristic, which is a source of conductive electromagnetic interference, in particular: adjustable DC and AC electric drives, uninterruptible power supplies of electric receivers, electric welding equipment, electric arc furnaces, induction heating installations, gas-discharge radiation sources. Due to the nonlinearity of the current-voltage characteristics, the above devices consume a non-sinusoidal current from the network, which causes harmonic distortion of the supply voltage, including the fundamental harmonic component and higher harmonic components that are multiples of the fundamental frequency. Non-sinusoidal voltage, in turn, causes additional losses of power and energy in the elements of the electrical network, causes overheating and accelerated aging of the insulation of electrical equipment, reducing its operational reliability and reducing service life, worsens the accuracy of electrical measurements, causes malfunctions in automation systems, telemechanics, relay protection, electronic systems and communications. Non-sinusoidal voltage significantly complicates the compensation of reactive power in the electrical network. Compensating devices are made on the basis of capacitors, whose electrical parameters (resistance, power, current) depend on both the magnitude of the supply voltage and its harmonic composition. The present article identifies problems and proposes solutions in terms of reactive power compensation and improving the quality of electrical energy in electrical networks containing thyristor voltage converters and frequency converters used in adjustable electric drive installations of industrial enterprises.

Abstract:

The paper present result of research concerning the problems of handling electronic and electrical waste that households produce at home and analysed the main problems associated with this issue in Ukraine and in the world. The object of the study was telephones (ukrainians use 53.6 million mobile communication devices), refrigerators, washing machines and TVs. The production of electrical and electronic equipment is one of the fastest growing global manufacturing activities. This development has resulted in an increase of waste electric and electronic equipment which constitute a risk to the environment and sustainable economic growth. Recycling of electronic and electrical waste is very expensive. There is a problem with electronic and electrical waste in Ukraine. To accumulate in the soil or to burn these waste is harmful. Every year on our planet about 50 million tons of electronic waste are generated. It was established that 53% of the interviewed students changed 1 phone in the last three years, 24% – 2 phones and 7% – more than 3. Students wanted a new phone. Most of the phones are at home, and the rest were given to their relatives or thrown into the trash. Ukrainians replace refrigerators, TVs and washing machines less often. Most Ukrainians change refrigerators. The largest amount of electronic waste is produced in Australia, New Zealand and Oceania (17.3 kg per inhabitant), in Europe – 16.6 kg per inhabitant and 11.6 kg waste per inhabitant of North and South America. In Japan, Norway, the Netherlands, Germany, Sweden and Poland, the process of disposal of used home appliances is well organized. However, economically developed countries utilize only part of the waste in their territory, while the rest are exported to landfills in Pakistan, Vietnam, Nigeria. The world's largest dump of electronic and electrical waste is in Ghana. To address potential environmental problems that could stem from improper management of WEEE, many countries and organizations have drafted national legislation to improve the reuse, recycling and other forms of material recovery from WEEE to reduce the amount and types of materials disposed in landfills.

Abstract:

Recently, the concept of “circular economy”, the design for end-of-life, the problem of reduction of waste of electronic and electrical equipment are becoming more and more important. The design of electronic systems for end-of-life considers the possibility of their repair, reuse and recycle, in order to reduce waste. This work proposes a new accurate model of failure probability density, that includes the failure probability of a used component in new equipment. The model has been tested, in conjunction with the International Electrotechnical Commission and Telcordia standard, in real industrial production. Eight years of historical faults have been analyzed and used to derive the fault models of the components. The model and analysis have been used for the analysis of real electronic products. The reuse of components could make an improvement to the reliability of the equipment.

Abstract:

With the development of the modern science and technology, new and high technology and the electronic instrument and equipment has been widely used in the referee work of the large scale track and field matches, which is also a prominent feature of the modern large scale track and field matches. Taking the referee work of the track and field match of the Ninth National Games as an example, this article carries on the discussion on the function of the electronic equipment in the large scale track and field competition, to provide a reference for further deepening the recognition and understanding of the characteristics of the modern large scale track and field matches. Present situation and the development of the sports electronic equipment Since the development of modern Olympic sports competition, sports have become a part of peoples life around the world. For more than 100 years, with the continuous improvement of the level of the competitive sports, the competition has become increasingly fierce, and in the competitive sports games, ranking the performance in one second per one hundred, or even one per one thousand seconds is very normal. So, quickly, accurately and fairly determining the timing and scoring of the achievement, and the instrument and the equipment assessing the scores have become one of the necessary sports facilities of the development of competitive sports. Early in the seventeen sixties, in the sports games there was the application of the mechanical stopwatch, and until the forties of this century, the development of light, machine, electric technology is gradually applied to the referee equipment of the sports matches. In the sixties of this century, the Swiss Omega company as the representative successfully promoted the timing and scoring devices to the sports industry with various applications of the electronic technology as the leading factor in the sports competitions, and has won the identification of the international sports organization. The increasing application of these electronic devices in sports competitions accelerates its development, and internationally the German Junghanns, the Japan Seiko and other companies also joined this field of research, with the development of their own products. In the eighties, with rapid development of the computer technology, and the appearance of various new materials, sports electronic equipment has reached a new level in terms of its reliability and automation. The use of the electronic judgment devices of the games, which can also promote the improvement and development of the sports electronic equipment, is clearer and clearer in the technical definition. Sports electronic equipment can be roughly divided into three categories. The first category is mainly the electronic equipment used in the automatic and semiautomatic timing and scoring of various sports competitions and the scoring system, such as track and field, swimming, weightlifting, rowing, winter sports, cycling, gymnastics, diving, all kinds of ball games, shooting, fencing etc. The second category is the various auxiliary training and monitoring equipment and instrument used for scientific sports training, to improve the sports performances, such as the swimming start, the Turing test, rowing strength telemetry, eight first telemetry, heart rate telemetry, photoelectric detection of firing stability, and the electronic equipment related to the athletes material selection. The third is the computer information system of the large-scale comprehensive sports games, such as the Olympic Games, the intercontinental games, and the National Games. The host countries and cities are using the competition opportunity to demonstrate its economic and technological strength. In addition to providing the first-class modern venues, the electronic information system has become one of the main equipment of the system during the general assembly, for journalists, sports teams and the public to understand the relevant information, it also provides the games with all service guides, to make the system function more and more complete, and more convenient to use. No wonder some people comment that the games of the Olympic level have become a window to display the technological progress and development of the world. Study and discussion on the sports electronic equipment Fully automatic electronic timing system The Ninth National Games use the SEIKO (2000HD) automatic electronic timing system for the timing, and this system is one of the world's most advanced timing systems, which is characterized by high resolution images, with the image resolution 419 million pixels (2048@2048H), more accurate interpretation, with the interpretation precision of the images up to 1/4000s, and large recording capacity, with the single 322MB and the dual 644MB, and one side recording 250 screens and the double 500 images, and the resolution up to 400dpi. The full automatic electronic timing system can print the color images of the athletes through the end after being amplified with the resolution 1/1000s, which effectively distinguishes the ranks of each athlete arriving at the end position and accurately judges the competition performance of the athletes. For example, in the men's 100m finals of the National Games, the performance of the top two is 10.25s, and their winning or losing is determined by 1/1000s. From the nineteen sixties, the large international track and field competition began to use the electric timing, and the current track events of 400m and below only admit the electric timing of the world and the national record.

Abstract:

Abstract Copper is widely used metal for industrial and public purposes due to its good corrosion resistance and excellent electrical conductivity. In indoor atmospheric environments with low level of air pollution the corrosion rate of copper is very low and it is not affected by slight increasing of temperature or relative humidity. In many indoor environment hydrogen sulphide (H2S) occurs and significantly affects the copper corrosion. CuS is a loose of black corrosion product which can’t form protective film on copper surface and promote corrosion by adsorption of moisture as carrier. In sulphide presence, the corrosion product is chalcocite Cu2S. Copper corrosion attack by H2S low concentration caused significant failure of electronic, electric equipment but also other copper parts as tubes, etc. These corrosion films can form an insulating layer on the contact surfaces causing electrical failures on the electronic devices.

Abstract:

The technical equipment of modern trolleybuses (increased power of traction motors, regenerative-rheostatic braking, anti-slip and anti-lock systems, an on-board computer for monitoring and controlling the operation of the traction drive, GLONASS satellite systems, Internet access) increases the requirements for the quality of electrical energy and the electromagnetic compatibility of the installed equipment. In the course of the study, the electrical performance of the trolleybus traction asynchronous motor (voltage, current, voltage sinusoidal shape, total coefficient of harmonic voltage components) has been analyzed. Due to difficulties in the supply of foreign electrical equipment, primarily power electronics elements used to control the operation of the traction motor, there is an increasing need to improve measures for the maintenance of trolleybuses to increase the reliability and uptime of the equipment. The advantages of using the methods of quantitative thermography, analysis of the quality of electrical energy and control of the hardness of cable insulation have been experimentally established. With the help of an analyzer of electric energy quality, measurements of the quantitative indicators of the operation of the electric motor have been carried out; the thermal imager has been used to assess the thermal state of contact connections and cable routes. The use of new diagnostic methods is of particular relevance in the course of continuous long-term operation of electric transport in the Far North.
