3:1 Voltage division ratio voltageratio
The ratio of the input voltage to the output voltage of a surge voltage divider:
3:2 Standard lightning impulse voltage standardlightning-impulsevoltage
Smooth lightning impulse voltage with a wave front time of 1:2 μs and a half-peak time of 50 μs:
Note 1: Generally, the wave front time is 0:84μs~1:56μs, and the half-peak time is 40μs~60μs, which can be considered as standard lightning impulse
Voltage:
Note 2: Oscillation near the overshoot and peak value is permissible, and the relative overshoot amplitude is allowed not to exceed 10%:
