The Lightning Impulse Test System for Power Transformers is designed for transformer manufacturers and high-voltage test laboratories that require accurate impulse voltage generation and waveform analysis.

Transformer insulation may be subjected to severe transient overvoltage stress during service. Lightning impulse testing helps evaluate the transformer's ability to withstand specified impulse voltage conditions.

The system can combine impulse generation, charging, triggering, waveform measurement and automatic analysis in one integrated platform.
