Sistema de Teste para Subestação Elétrica CPC 100

Sistema de Teste para Subestação Elétrica – CPC 100

O CPC-100 fornece mais de 800 A (ou 2000 A com amplificador de corrente), e 2000 V. Inclui um PC integrado. A rotina do software testa grande parte dos equipamentos da subestação, criando automaticamente relatórios configuráveis. O design compacto (29 Kg/ 64 lbs) e o software inovador poupam tempo de teste, com geração automática de relatórios e minimizam o custo de transporte.

Aliado ao CPC-100, o CP TD1 permite realizar testes automatizados de Capacitância, Fator de Potência e Tangente Delta, para avaliação das condições do isolamento com 12 KV e variando a freqüência de 15 a 400 Hz.

O CPC 100 + CP TD1 é ideal para a realização de testes primários, testes de manutenção em campo, com variação de frequência de 15 A 400 Hz nos seguintes equipamentos:
•Transformadores de Potência
•Transformadores de Corrente
•Transformadores de Potencial
•Chaves
•Cabos
•Máquinas Rotativas

 Abstract —The efficient supply of electric power relies strongly on the selection of suitable voltage levels for different sections of the energy distribution system. When higher levels of power are required, a medium-voltage level in the tens of kilovolts range is typically selected. In accordance to current trends in energy conversion, the supply of power must fulfil several functionality requirements among which high power-quality and access to a low-voltage DC interface can be highlighted. Moreover, low energy losses, high power-density, low failure rate and low total cost of ownership remain as major research challenges. Solid-state-transformers (SSTs) comply with these functionality requirements as well as with the demanded high performance levels while directly connecting to medium-voltage.

A Study on Optimization of Compact High-voltage Generator Based on Magnetic-core Tesla Transformer Young-Kyung Jeong*, Dong-Gi Youn** and Moon-Qee Lee†

Abstract – This paper presents a compact and portable high-voltage generator based on magneticcore
Tesla transformer for driving an UWB high power electromagnetic source. In order to optimize
the performance of the high-voltage generator, a novel open-loop cylindrical magnetic-core adopting
the quad-division lamination structure is proposed and manufactured. The designed high-voltage
generator using the proposed magnetic core has a battery-powered operation and compact size of 280
mm × 150 mm in length and diameter, respectively. The high-voltage generator can produce a voltage
pulse waveform with peak amplitude of 450 kV, a rise time of 1.5 ns, and pulse duration of 2.5 ns at
the 800 V input voltage.

1. Introduction
There has been active research to develop environmentally friendly products due to the recent increase in the oil prices and the reinforcement of strict environmental regulations worldwide. In particular, in order to develop environmentally friendly vehicles, there is active research in the automotive industry, which utilizes an immense amount of oil resources, on the drive system using electric motors and power-conversion systems that may potentially replace the conventional internal combustion engine [1, 2]. PHEV(Plug-in Hybrid Electric Vehicle), NEV(Neighborhood Electric Vehicle) and the general EV(Electric Vehicle) are examples of the new ecological vehicles. Such vehicles use electricity as its auxiliary and main power source, and battery is used as the energy source to drive their electric motors.
