Transformer Short-Circuit Withstand Capability Test System

System Overview

It is primarily used for short-circuit withstand capability testing of 10kV distribution transformers.

The test system utilizes high-efficiency energy storage and power electronic inverter technologies to deliver controllable, short-duration, high-capacity test voltages and currents, thereby meeting the requirements for high-voltage and high-current testing across a wide range of distribution network electrical equipment. Through units dedicated to charging, energy storage, and power inversion, the system isolates itself from the utility power supply, preventing transient test surges from impacting the grid.

The system features military-grade, long-life, high-energy storage capacitors alongside proven digital control and power inverter units, ensuring exceptional durability. Additionally, the flexible SPWM modulation scheme allows for the convenient adjustment of test parameters over a wide range.
