The test system for power transformers WV is used for transformer testing in the factory. It enables induced AC voltage tests, measurement of no-load currents and losses, short-circuit impedance and short-circuit loss measurements, as well as temperature rise and special tests according to international standard IEC 60076, parts 1 to 3. The powerful and converter-based test system generates a precise testing voltage with low total harmonic distortion (THD) and partial discharge (PD) level.
Key features
» THD < 5 %
» PD noise level < 10 pC
» Free adjustable frequency 40 Hz to 200 Hz
» Modular design allows for future expansion
» Highly accurate and calibrated power loss measurement - no determination of final measurement uncertainty necessary
» Low investment and life-cycle costs
» Converter in its own air-conditioned container and various cooling options allow the converter to be set up without additional building air conditioning
