This video explains the main functions and practical uses of the Lightning Impulse Test System in a clear, step-by-step format. You'll see how this high-voltage testing solution generates standardized lightning impulse waveforms to simulate real lightning overvoltage conditions and verify insulation performance in transformers and other electrical equipment. We demonstrate the system's capabilities for full wave, chopped wave, and switching impulse tests, showing how engineers can identify insulation weaknesses before equipment enters operation.
