GOZ-CR Pulse voltage divider

    The GOZ-CR pulse voltage divider is a weakly damped equipotential shielded high-voltage measurement system, mainly used for lightning surge measurement, including lightning full wave, 8/20us wave, and other lightning waveforms. It is a specialized resistor divider for lightning surges, featuring easy operation, intuitive display, high accuracy, small size, and light weight. It is 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  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 capacitor voltage divider, lightning impact high voltage pulse divider, impulse voltage pulse divider, weakly damped pulse divider.

Product Features:

1、Adopting balanced equipotential shielded structure.

2、The fully sealed insulation tube internally uses high-quality electronic components, ensuring accurate testing and good linearity of the entire device.

3、High precision, high linearity, high stability, and anti-interference.

4、Using oil-immersed insulation to minimize partial discharge inside.

5、Internal shielding anti-interference system, comprehensive pressure equalization measures, single-section or multi-section structure.

6、Internally using high-precision resistors and high-voltage capacitors with low dielectric loss tangent, resulting in minimal partial discharge.

Product Parameters:

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

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