Impulse Voltage and Impulse Current Generator for High Voltage Electrical Equipment, Transformer Insulation and Impulse Withstand Testing

General Information

The SXCY Series High-Voltage Impulse Test Generator is developed for laboratories and electrical equipment manufacturers that need to evaluate insulation systems under short-duration, high-intensity electrical stress.

The system generates controlled impulse voltage or impulse current for testing the dielectric strength of high-voltage equipment. By reproducing severe transient conditions in a laboratory environment, it provides engineers with a practical way to verify the withstand capability of electrical insulation before equipment is put into operation.
