AC Resonant Test System for Testing High-Voltage Cables and Electrical Equipment

DESCRIPTION / TECHNICAL SPECIFICATIONS

AC Resonant Test System is a high voltage testing system based on the series resonance principle for AC withstand voltage testing of electrical equipment. It is designed for insulation and withstand voltage testing of high voltage equipment.

The system can be used for testing high voltage cables, transformers, generators, GIS, switchgear, bus bars, and substation equipment. With a working frequency range of 30 to 300 Hz, the system provides flexibility for various high voltage testing applications.

The system consists of a variable frequency power supply, exciter transformer, high voltage reactor, and capacitive divider, with protection functions including overvoltage, overcurrent, zero start, detuning, and flashover protection.

The series resonant technology helps reduce the required active power while providing high AC test voltage with a sine wave output. It is suitable for industrial electrical testing, laboratories, power utilities, and high voltage equipment testing applications.
