The series resonance withstand voltage test device uses a variable frequency power supply to convert the power frequency (50Hz)



The series resonance withstand voltage test device, also known as the variable frequency series resonance device, is a professional power testing equipment based on the principle of LC series resonance. It is mainly used for AC withstand voltage tests on capacitive power equipment with large capacity and high voltage (such as high-voltage cables, GIS, large transformers, etc.), and is a key tool for ensuring the safe and stable operation of the power system.
