High Voltage Series Resonance Test System Variable Frequency AC Withstand Voltage Test Equipment for XLPE Cable, Power Transformer, GIS and Substation Equipment
The High Voltage Series Resonance Test System is engineered for high-voltage AC withstand testing of electrical equipment used in power transmission and distribution systems.
It is particularly suitable for testing XLPE power cables, power transformers, GIS, circuit breakers, busbars and other substation equipment.
The system uses a frequency-controlled power supply, excitation transformer, high-voltage reactor and capacitive voltage divider as its main components.

Q: What frequency range is available?
A: Depending on the model, variable-frequency systems commonly cover ranges such as 20–300 Hz or 30–300 Hz.
Q: Can the system test long XLPE cables?
A: Yes. Series resonance is particularly suitable for capacitive cable loads, with the final cable length and voltage determined by the system's rated capacity, reactor configuration and test requirements.
