Transformer Test System

The test system for power transformers is used to perform the induced AC voltage test, the measurement of no load loss and current, the measurement of short circuit impedance and load loss, the temperature rise test and special tests according to the international standard IEC 60076 parts 1 to 3. The test system is based on the state-of-the-art frequency converter and carries out tests implementing the precise waveform with a total harmonic distortion (THD) < 5 % and a partial discharge
(PD) noise level < 10 pC. The test system is maintenance-free and with its low investment costs and minimal installation requirements it has particularly low lifecycle costs. The test system is highly efficient due to fully-automatic testing procedures. Furthermore, the modular design of the test system allows for future expansions.
