The Short Circuit Test System is a capacitor-based intelligent power supply designed for short-circuit performance verification of electrical equipment.
It provides stable, repeatable short-circuit current output and precise waveform recording, fully compliant with IEC standards for type and routine testing.
The system supports short-circuit tests for transformers, LV switchgear, MCCB/ACB, and protection devices, and is suitable for laboratory accreditation and factory acceptance testing (FAT).
Main Functions：
Short-circuit test for transformers (IEC 60076-5)
Short-time withstand current test for LV panels
Conditional short-circuit test for MCCB / SCPD
Ultimate short-circuit breaking capacity test (Icu) for MCCB & ACB
Short-circuit breaking test for HRC fuses (IEC 60269)
Waveform recording and analysis for all test channels
