Lightning Impulse Test System EPDY-300kV 30kJ Delivered

The EPDY-300kV 30kJ Lightning Impulse Test System is used for carrying out standard lightning impulse voltage full wave and chopping wave test on power transformer, HV apparatus such as high voltage switchgear, power capacitors, clearance, bushings, and CT/PT.

Also called: impulse voltage test system

The number of standard lightning impulse voltage waveforms: 3 (standard lightning full wave, lightning chopping wave and flaw detection current wave).

1. Standard lightning impulse voltage full wave 1.2±30%/50±20%μs, efficiency is more than 85%.

2. Standard lightning impulse chopping voltage waveform, efficiency: not less than 85%,
The chop off device can produce lightning chop-off waves with a chop-off time of 2 to 6 μs.

3. The full-wave waveform of the defect current for the lightning impulse voltage test of the transformer reactor.

The full system is consisted by following:
-300kV/30kJ lightning impulse voltage generator body 1 Set
-300kV/500pF low damping load type lightning impulse capacitor divider 1.0% 1 Set
-Impulse voltage test computer automatic control system 1 Set
-Automatic digital impact measurement and analysis system 1 Set
