Impulse Voltage Generator System

Application

CJDYE series impulse test systems can be used to generate impulse voltages simulating lightning strokes and switching surges to test insulation level of the equipment under 132kV. It also can be used in the research of the effects that insulator pollution has on impulse flashover voltage and impulse characteristic of un-uniform pollution. 


Type options:


E typeV typeH type
up to:1800 kVup to:4800 kVup to:7200 kV
up to:180 kJup to:600 kJup to:1620 kJ


To generate impulse voltages for testing:

  • Transformers

  • Cables

  • Gas-insulated switchgears (GIS)

  • Arresters and other high-voltage devices

  • For material testing in research or training programs

  • For both factory and on-site testing
