Product Description
Wuhan EP Hipot 36kV Power Transformer Lighting Impulse Voltage Test System 400kV 30kJ
 
 
Product Description

Applications:
This lightning impulse test system is used for carrying out standard lightning impulse voltage full wave and chopping wave test on 36kV and below power transformer, HV apparatus such as high voltage switchgear, power capacitors, clearance, bushings, and CT/PT.

 

Product Parameters

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.
