Free Partial Discharge Frequency Converter Free Partial Discharge Frequency Converter is suitable for inductive pressure-resistant test, local discharge test and series resonant test. With the isolation of boost transformers, reactors, bureau putter, etc. to form a voltage standing test system. Free Partial Discharge Frequency Converter adopts the principle of linear power amplification to convert the standard sine wave signal of variable frequency into a high-power test power supply, the waveform distortion is small, and the local discharge is less than 10pC to meet the needs of local partial discharge voltage stand test. Free Partial Discharge Frequency Converter is small in size and light in weight, and can be moved, suitable for field use. Power supply has multiple protection measures such as lack of phase protection, under voltage protection, overvoltage protection, temperature protection, short circuit protection, overcurrent protection, power protection and so on.
