In this paper, a novel 800V multiple RESURF lateral double-diffused MOS (LDMOS) transistor in junction-isolated power IC technology is developed and successfully simulated. The proposed multiple RESURF LDMOS is able to achieve a specific on-resistance of lower than 130 mΩcm2 while maintaining a breakdown voltage of over 800 volts. The key feature of this novel device is round shape p-top rings which are located on the surface of n-drift region. Optimization of p-top mask design is performed in order to achieve the lowest on-resistance possible with the desired breakdown voltage. An investigation of 3D effect in cylindrical layout is also presented to confirm the performance of device.

This paper describes the failure analysis of a section insulator assembly at one of the depot of Delhi Metro Rail Corporation Limited (DMRCL). Frequent breaker tripping at Saritavihar depot of DMRCL due to flashover of the section insulator assembly was observed; the cause of failure of the section insulator was investigated and presented in this paper. As a first step laboratory tests on new and used section insulator assemblies were conducted to make comparative analysis, and then simulation studies were carried out to estimate the possible over voltages during different switching operations and their relationship with the test voltages used in the experimental investigation. This paper presents the laboratory experiments and simulation studies for the failure analysis of section insulator assembly of DMRCL.

The purpose of this paper is to investigate the severity of lightning induced voltages on a gas pipeline installed in parallel with overhead transmission line using two different simulation packages. The results from this study using CDEGS, which solves a given problem based on electromagnetic computations, reveal that the induced voltages on the pipeline are more accurate compared to that obtained by PSCAD simulation, which is based on the circuit approach. Unlike PSCAD, CDEGS considers many salient factors such as soil model, inductive, capacitive and conductive couplings, and multiple soil structures. Models of a double circuit 132kV transmission line, gas pipelines, soil with different resistivities and variable lightning surges were developed. The effects of pipelines located at various heights above ground and distance of pipeline from the power lines were also studied. Compared to previously published work using PSCAD, it is found that CDEGS has given more accurate results. Several findings which were not possible using PSCAD were observed such as the effect of soil structure on induced voltage and multiple layers soil. This also led to better understanding of the conductive coupling from lightning strikes and fault conditions. The modeling work using CDEGS not only useful for providing more reliable data for further protection and mitigation techniques, but is also very versatile to study the effects of various other important factors affecting the induced voltage on the pipelines.

El desarrollo de la Alta Tensión en Corriente Continua (en adelante, HVDC) tiene un futuro brillante por delante. Cuando se encuentra totalmente coordinada con otros equipos e integrada con el sistema general, esta versátil tecnología proporciona la capacidad de controlar la potencia real y reactiva, regular la frecuencia, mejorar la estabilidad, interconectar sistemas asincrónicos, transferir potencia económicamente a través de largas distancias, evitar las congestiones de la red e inyectar energía donde sea necesario, o aplicar extensas instalaciones subterráneas o submarinas, entre otras ventajas.

Electric radiation fields produced by lightning cloud flashes have been analyzed using Fourier methods to obtain amplitude spectra for frequencies in the range of 20 kHz to 20 MHz. Time to thunder measurements were used to extract the distances to the cloud flashes from the measurement site. The spectra were generated by analyzing the first 10 ms time window of cloud flashes with 10 ns sampling resolution, and they show f-1 frequency dependence up to 2 MHz followed by f-2 dependence and higher for frequencies above 2 MHz. The results agree very well with previous measurements carried out for individual pulses produced by various lightning processes. By utilizing digital filters, it has been shown that measurements taken with narrowband filters agree with the results produced under wideband measurements

Partial discharge measurements on transformers and rotating machines are an accepted tool of quality control, in factory and on site. Common methods to improve the quality of noisy PD data are filtering and gating. Recently a new method was introduced, which is able to clearly separate different PD sources within the DUT as well as separate PD from noise. This multi-channel synchronous measuring method compares amplitude relations of simultaneous PD sources of three phases (3PARD). PD pulses propagate from its origin to the decoupling site, even cross-coupling to the other phases. PD from different locations inside the insulation will lead to unique pulse triples at the 3 decoupling positions. The amplitude relations of the 3 synchronous decoupled pulses of one pulse source will be nearly constant. That allows a classification of different noise sources and single PD failures within the DUT by comparison of these amplitude relations. As a new approach of PD source separation the 3PA...

Transformer-less inverters are necessary parts for grid-connected renewable energy resources (RERs). Due to its cost effectiveness, downsize and less weight, great attention has been paid to these inverters development. With these aforementioned advantages, these inverters have limitations like the flow of leakage current through PV arrays, high total harmonic distortion (THD) at inverter's output and DC current injection to the grid. This paper presents coupled inductor based single-phase transformer-less semi-Z-source inverter topology to lessen those limitations. Since the DC input and AC output voltage share a common ground, the presented inverter system is categorized under doubly grounded topologies. For the purpose of handling the nonlinearity of the voltage gain of semi Z-source inverter, a nonlinear sinusoidal pulse width modulation (SPWM) technique has been employed. The prototype of the suggested inverter has been constructed. The performance and compatibility of modulation technique are verified under different loading conditions. The feasibility of the configuration is ensured based on the mitigated common mode leakage current, the substantially lower THD as well as DC current injected to the grid. Moreover, the presence of coupled inductor significantly contributes in reducing input current ripple, installation area of the inverter and enhancing the efficiency. Finally, this topology exhibits appreciable performance to operate synchronously and transfer power to the grid.

This paper explains the implementation of a small-signal model for a new five-level series resonant inverter structure. The proposed circuit combines the advantages of multilevel inverters and the characteristics of the physical phenomena, resonance. The small-signal model offers the possibility to design a linearized linear time-invariant (LTI) model around an equilibrium point based on the first-order Taylor series. After that, the performance of the proposed five-level series resonant inverter and its small-signal model are evaluated in MATLAB/Simulink environment. Compared with a MATLAB model generated using the system identification toolbox, the developed small-signal model exhibited a good accuracy in frequency and time domains. In addition, a hardware test bench is developed to validate the proposed model. Both simulation and experimental results show that the proposed multilevel resonant inverter is very interesting for high-voltage high-frequency applications. As a perspective, from the results obtained, we suggest the use of small-signal AC analysis for multilevel series resonant inverter modeling. The paper contains rich information on the recently used tools for dynamic systems modeling and analysis of nonlinear processes that can be applied to modeling and analyzing other power electronics inverters.

Improving power quality play a vital role in distribution systems since, these are majorly connected to nonlinear loads. Nonlinear loads generate harmonics which in turn disturb the source of supply. The damped double tuned filters can be designed either by using equivalent method or parametric method but, the parametric method is most preferable because of consideration of reactive power demand of the nonlinear load. In this proposed research paper various types of damped double tuned filters have been designed for different nonlinear loads and a comparison was made between aforementioned two methods when connected to different nonlinear loads. A flowchart has been developed to optimize the damped double tuned filter parameters and tested by using MATLAB programming.

—In this paper, we calculated the induced sheath voltage in metallic sheath/shield of single-core cables operating in double circuit by considering influence of arrangement and phase distance; with the aim of providing optimal value of phase distance and proper arrangement to reduce the induced voltage. Five different arrangements of the cables are used to investigate the effect of a single point bonding and the double point bonding on induced voltage. Formulae for different arrangements are derived using IEEE guide to calculate induced sheath voltage. Out of five arrangements, independent horizontal and vertical arrangements have provided better results. It is found that the independent horizontal arrangement provides lesser maximum induced voltage of 132 V/km but higher overall induced sheath voltage of 64.28 V/km when compared to the vertical arrangement. The vertical arrangement has the values of maximum induced sheath voltage of 138.8 V/km and the overall induced sheath voltage of 27.79 V/km. This causes obvious decrease in the circulating current in the metal shield of the cable which makes independent vertical arrangement better than independent horizontal arrangement with respect to personnel safety. These findings can be used to suggest proper phase distance, radius of the cables and their arrangements when operating in double circuit to reduce the induced sheath voltage in metal sheath of a cable. Keywords—Double circuit, single circuit, induced sheath voltage, single core cables, electromagnetic coupling effect

Research on alternative dielectric gases to eliminate the disadvantages of SF6, which is widely used in GIS and switching systems in the power system engineering, has been an important study topic in the literature for nearly 40 years. Because of environmental priorities defined by international agreements such as the Kyoto Protocol and Doha Amendment, the restrictions on the use of SF6 make these studies an obligation. Although the number of alternative dielectric gases studied for this purpose is quite high, these gases can be classified under the titles of non-synthetics, hydrocarbons (HCs), fluorocarbons (FCs), hydrofluorocarbons (HFCs), fluoronitriles (FNs), fluoroketones (FKs) and other synthetic gases. In this study, the gases classified under these titles are compared using the dielectric constant relative to SF6, Global Warming Potential (GWP), atmospheric lifetime, boiling point and toxicity parameters used in the comparison of dielectric gases. When compared with these pa...

A negligible percentage of the cost of a Power Generation Plant or Transmission network goes towards the cost of insulators, yet the cumulative O&M costs, outage costs and equipment damage costs due to poor insulator performance can be staggering. Entire transmission grids have been known to collapse due to a pollution flashover on a single insulator. Common practices to try and attain uninterrupted performance of outdoor porcelain and glass insulators include live-line Insulator washing, application of silicone grease, specially designed ‘anti-fog insulators’, contamination source reduction and increased maintenance surveillance. These methods often fail to prevent failures and are at best temporary solutions.

One of the methods adopted to eliminate pollution flashovers is the use of RTV Silicone Insulator Coatings. Widespread field experience suggests this could be one of the most promising methods to eliminate flashovers, even in the harshest environments.

This paper reviews field experiences of gen-4 RTV Silicone HV Insulator Coatings (HVICs) in very heavily polluted environments and how they have had an exceptional success rate in eliminating flashovers, even when all other methods have failed.

A flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer. It was initially designed to generate high voltage sawtooth signals at a relatively high frequency. In modern applications it is used extensively in switched-mode power supplies for both low (3V) and high voltage (over 10 kV) supplies.

Geiger-Müller (GM) tube based radiation detectors require high voltage DC biasing for
their operation. The objective of this project is to design and implement a variable DC
power supply of 3kV/10mA with short-circuit protection for GM detectors. The proposed
design is based on rectification of AC 220V followed by a buck converter to generate a
variable DC supply of 300V. A square wave of variable amplitude is generated from the
variable DC supply through semiconductor switches. The square wave is fed to a 16-
stage Cockcroft Walton’s multiplier to generate variable DC supply of 3kV with a
resolution of 10V and ripple of less than 2mV at rated current of 10mA. The variable
output voltage is controlled and regulated by employing feedback control using
microcontroller and voltage sensors.
This dissertation sums up the work done on this project. It includes requirements
analysis, comparative study of different approaches followed by selection of Cockcroft
Walton’s multiplier as the most appropriate design. For the selected design, a parametric
study is presented based on simulation results followed by hardware implementation. It
also includes the development of a feedback control system to control and regulate the
high voltage DC output. The thesis includes the testing and evaluation of the
implemented design and formulates suggestions for further research and development on
detector bias supplies.

In the past few years there is a rapid improvement in power distribution sector, but the set of equipment require for controlling the transmission and distribution of electric power supply remains the same. This paper gives an overview about the design of gas insulated metalclad switchgear (GIS) and its technologies. The steps of technical development, stages of technical design, state of the art in the production, and quality insurance are explained with the help of practical example. This paper also highlights the difference between traditional sub-station i.e. Air Insulated Substation (AIS) and modern sub-station i.e. gas insulated metalclad switchgear (GIS). According to research, GIS is more reliable, multi-component and maintenance free as it need very less space. It also describes about the operational primary equipment such as switching, grounding, disconnecting, secondary system, gas handling, maintenance, and monitoring and the primary insulation medium SF 6 gas and its properties. This paper indicates numerous advantages of gas insulated metalclad switchgear and, GIS is not only used for indoor sub-stations but also can be used for outdoor sub-stations. There are some drawbacks that may occur in GIS, but with many advantages it is urged that at High voltage level of 12kv, 36kv, 72.5kv, 145kv, 245kv, 420kv and above GIS must be used from the point of view economic, low maintenance cost, easy installation, long life and it require very little space as compare to other conventional sub-station of same rating.

Energy is one of the most vital requirements for economic and social development of any country. With the increase in power generation requirement, the size of generators & motors is also increasing. The continuing increase in output coefficient of machines has led the tendency to increase the copper size & reduce the insulation level for the same slot size, thus a comprehensive study of electrical stresses is required for designing a reliable insulation system. Insulation system play a vital role on reliability of high voltage rotating electrical machines used for power generating equipments, insulation failure may result in machine failure & ultimately system breakdown & costly repair. High voltage induction motors play a vital role in reliable operation and performance of process industries and utilities of power plants. H.V. motors are used to drive boiler feed pumps, primary air fan ,cooling water pumps, induced and forced draught fan drive motors, mill motors and other utility operation in thermal power plants . Induction motors have been the most popular electric motors in the family of motors. The failure data on large induction motors indicate that the stator related failure account for about 37% of the total failure. This paper deals with details of insulation systems for Large H.T. motors which are widely used for driving various thermal power plant auxiliaries such as induced draft fans, boiler feed pumps, cooling water pumps, coal crushers & conveyors.

Abstract—Supervisory Control and Data Acquisition (SCADA) systems are deeply
ingrained in the fabric of critical infrastructure sectors. These computerized realtime
process control systems, over geographically dispersed continuous
distribution operations, are increasingly subject to serious damage and
disruption by cyber means due to their standardization and connectivity to
other networks. However, SCADA systems generally have little protection from
the escalating cyber threats. In order to understand the potential danger and to
protect SCADA systems, this project is to study the possible vulnerabilities of
SCADA system and to present a set of security oriented goals.

—The vital role of power transformers in the power system has attracted the consideration of Condition based Maintenance for many years. Dissolved gas in-oil analysis (DGA) has gained popularity in condition monitoring and diagnosis through its diagnosing methods like Key Gas, Dornenburg, Rogers, IEC and Duval Triangle. This paper presents the implementation of computer based software with Database for transformer condition monitoring with the use of Dissolved Gas in-oil Analysis. It involves database for storage of DGA information in which they can be retrieved by the software for fault diagnosis through the use of five diagnostic methods (Key Gas method, Dornenburg ratio method, Roger's ratio method, IEC ratio method and Duval Triangle method). 50 samples from other researchers were taken, stored and tested for proving the performance of the DGA software. The DGA software showed the accuracy of more than 90 percent in fault interpretation (with the use of Duval Triangle). The implementation involved the use of database made with MySQL 5.5 for storage of DGA information, DGA software made with Python 2.7 and compiled with Eclipse in Ubuntu 14.04 (computer operating system).

A switchgear installation contains all the apparatus and auxiliary equipment necessary to ensure reliable operation of the installation and a secure supply of electricity. Threephase a.c. high-voltage switchgear installations with operating voltages of up to 800 kV are used for distributing electricity in towns and cities, regions and industrial centres, and also for power transmission. The voltage level employed is determined by the transmission capacity and the short-circuit capacity of the power system. Distribution networks are operated predominantly up to 123 kV. Power transmission systems and ring mains round urban areas operate with 123, 245 or 420 kV, depending on local conditions. Over very large distances, extra high powers are also transmitted at 765 kV or by HVDC (high-voltage direct-current) systems.
