Purpose:
The series impulse voltage generator is mainly used for lightning impulse voltage full wave, lightning impulse voltage chopped wave, switching impulse voltage wave and steep wave impulse voltage tests on power equipment such as power transformers, instrument transformers, combined electrical composite insulators, arresters, etc., to verify insulation performance.
Performance:
The 1200kV/2400kV and 4800kV series impulse voltage generators can produce three types of impulse waveforms: standard lightning full wave, switching wave, and lightning chopped wave. The 1200kV series impulse voltage generator can produce eight types of impulse voltage waveforms: standard lightning wave, switching wave, lightning chopped wave, oscillating lightning wave, oscillating switching wave, line insulator steep wave, composite insulator steep wave, and transformer induced switching wave. The technical indicators comply with national standards and IEC standards, have passed ministerial appraisal, and the main technical performance is at the leading domestic level, reaching the advanced level of similar international products.
