Product Description
Product Description
450kV 20kJ High Voltage Impulse Voltage Test System for Lighting Test
Rated parameter value
Rated nominal voltage ：±450kV
Rated voltage ：±150kV
Rated energy：20kJ
Total impulse capacitance：0.25μF
The total series ： 3 series
Rated power capacity：1μF
The following waveforms can be generated when the load capacitance is 300~5000PF：
2±30%/50±20%μs Lightning impulse voltage full wave，The efficiency of voltage≥92%(no-load )
standard impulse voltage cut wave 2~6μs，The efficiency of voltage≥92% (no-load)
The impulsevoltage waveform parameters all meet the requirements of IEC and GB311-97 national standards
Class voltage within 10% ~ 100% rated voltage range positive and negative synchronous range is not less than 20%.
Ignition range 10%～100%
Synchronous discharge rate out of control：＜ 2%
Minimum output voltage：≤10un
Charging voltage instability：≤±1.0%
Service duration: > over 70% UN rated voltage can operate continuously every 90 seconds. Under the rated voltage of <70% UN charging and discharging once every 45 seconds can run continuously.
