YDGK Series Resonant Test System - Maximum Voltage up to 2000kV

Series Resonant Test System (Inductance-Adjustable Type)

Application

The Series Resonant Test System is suitable for capacitive test objects, such as cables, generators, and transformers, meeting IEC and other national standards.

Product Features

Voltage up to 2000kV, high reliability, low partial discharge.

Low noise, high Q factor.

Fully digital measurement and control, full fiber optic communication, superior electromagnetic compatibility.

Comprehensive overvoltage protection, extremely high operational safety.


Series Resonant Test System (Frequency-Tuned Type)

Application

The Frequency-Tuned Resonant Test System is suitable for on-site testing of long cables and GIS/GIL. It increases voltage and current through series and parallel configurations, with individual resonant reactor voltages of 260kV, 360kV, 520kV, and 720kV, meeting on-site testing requirements for long-distance cables up to 550kV.

Also applicable for testing GIS/GIL up to 350kV.

The Frequency-Tuned Resonant System is suitable for on-site withstand voltage tests of SF6 circuit breakers, GIS, XLPE cables, and other capacitive test objects, as well as partial discharge tests of instrument transformers and coupling capacitors up to 1000kV.

Product Features

Compact size, lightweight

High Q factor

Wide frequency range

Low partial discharge
