GOZ-FY High Voltage Pulse Resistor Divider

    The GOZ-FY high voltage pulse resistor divider is primarily used for lightning surge measurement, as well as voltage measurement of power frequency and impulse high voltages, including lightning full wave, 8/20us wave, and other lightning waveforms. It is a specialized resistor divider for lightning surges, suitable for type tests of primary equipment in power grids (such as steep wave tests of zinc oxide surge arresters, lightning full wave tests of voltage transformers, lightning full wave tests of high-voltage switches, type tests of main transformers in substations, high-voltage GIS tests, etc.), substations, high-voltage electric equipment manufacturers, and high-voltage test laboratories as an ideal equipment for lightning surge measurement.

    We, at GOZ Electric, specialize in the production and supply of  High Voltage Pulse Resistor Dividers. With a good market reputation and a professional technical team, we have years of experience in developing pulse divider series. Our equipment comes with a three-package guarantee and can provide a testing report certified by the China Electric Power Research Institute upon request.

    Also known as high-voltage pulse divider, resistive voltage divider, lightning high-voltage pulse divider, lightning impact high-voltage pulse divider, and impulse voltage pulse divider.

Product Features:

    The GOZ-FY high voltage pulse resistor divider is connected to the oscilloscope via instrument cables, enabling clear readings from a distance, and it is safe and convenient to use. This series of pulse resistor dividers has high input impedance, good linearity, adopts special shielding technology to reduce the influence of high voltage on the reading, and achieves high stability.

1、Oil-filled resistor dividers use high-precision resistance wire imported from Switzerland, with small size and good stability.

2、Dry-type resistor dividers use military alloy resistors, with smaller size and lighter weight.

Product Parameters:

Voltage Level: AC: 50kV - 2000kV (able to withstand impulse voltage peak of 110% rated value)

Response Time: <120ns (can be designed and made according to special requirements)

Impulse Voltage Waveform: Lightning surge full wave (referred to as lightning full wave). Main parameters include peak value UP, front time T1, half-value time T2, with standard lightning full wave having front time T1 = 1.2us and half-value time T2 = 50us. To obtain highly accurate test data, it is recommended to use an oscilloscope from Tektronix with a bandwidth of over 200M, and other technical indicators must meet the requirements for high-voltage lightning wave measurement.
