GOZ-FY High voltage test equipment
GOZ-FY high voltage pulse resistor divider is mainly used for lightning pulse wave measurement, and the voltage measurement of frequency and impact high voltage, including the lightning full-waveform, 8 / 20us waveform and other waveforms. As the special lighting pulse divider, it is suitable for grid primary equipment type test (such as zinc oxide arrester lightning steep wave test, e voltage transformer lightning full wav test, high voltage switch lightning full wave test, substation main transformer type test, high voltage GIS test, etc.), substation, high voltage electrical equipment manufacturing factory and high voltage laboratory and other departments. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities inspection, and issue a partial discharge ultrasonic positioning system test report.
Also called: high voltage pulse divider, resistor divider, lightning high voltage pulse divider, impact voltage pulse divider
The high voltage pulse resistor divider connected oscilloscope by meter lines, which can achieve remote clear reading, safe and convenient. The series equipment has features such as high input impedance, good linearity, using special shielding techniques to reduce the impact of high voltage, and gaining high degree of stability.
1, Oil-type resistor divider adopts Swiss imported high precision resistor, smaller size and better stability.
2, Dry-type resistor divider adopts military using alloy resistance, smaller size and lighter weight.
1. Voltage degree：AC:50kV -2000kV( peak: 110% rated impact voltage)
2. Response time：<120ns（Special requirements can be customized）
3.Impact voltage waveform：
Lighting impact full-wave（for short: lightning full-wave） main parameters are peak UP, wave front-time T1、half-peak time T2, while standard lighting full wave front-time T1=1.2us, half-peak time T2=50us.
