The NRP series impulse voltage divider meets the GB/T16927.2-1997 standard and is divided into resistance type impact voltage divider and weak damping resistance capacitance impact voltage divider. The accuracy of the resistance type impact voltage divider is suitable for measurement units, with an accuracy of 0.5% and 1%; The accuracy of weak damping resistance capacitance impact voltage dividers is lower than that of resistance type impact voltage dividers, with a general accuracy of 2% or 3%. Impulse voltage generators larger than 1000kV are often equipped with weak damping resistance capacitance impact voltage dividers. Resistance type impact voltage dividers have lower impedance due to their good square wave response.

Models
(2) Response time: < 20ns (special requirements can be customized)
(3) Impulse voltage waveform:
Lightning impulse full-wave (referred to lightning full-wave). The main parameters are peak UP, wavefront time T1, half-peak time T2, the wavefront time of standard lightning full-wave is T1 = 1.2us, the half-peak time of standard lightning full-wave is T2 = 50us.
In order to obtain high accuracy test data, it is recommended to use an oscilloscope above 200M.

(5) Insulating medium: imported capacitor oil
(6) Environmental conditions:
Temperature: 0 ~ 45 °C
Humidity: < 85% RH
(7) Divider ratio: approximately 1000:1 (different voltages have different partial voltage ratios)
