HV Test for Power Transformer
The on-site test system for power transformers is able to perform induced AC voltage tests, the measurements of no-load losses and current, the measurement of shot-circuit impedance and load loss, the temperature-rise test, an special test according to the international standard IEC 60076.
The test system is based on the state-of-the-art frequency converter technology and carries out tests generating a precise voltage waveform with a total harmonic distortion (THD) <5% and partial discharge (PD) noise level <20pC.
The modular design and the newest digital control technology allow two or more test systems to be connected in parallel making its posible to test even largest power transformer in the GVA range. Generally the test system can be set up on-site within an hour. There is no need for additional “lifting” or “assembly”.
The applications are:
1. Induced AC voltage test
2. Measurement of no-load loss and current
3. Measurement of short-circuit impedance and load loss
4. Temperature-rise test
5. Special test
