I Description
Variable-frequency resonance voltage raising device makes reactor and capacitor achieve resonance by adjusting frequency of power, and then obtain high voltage and big current on the test objects.
The system is comprised of frequency power, exciting transformer, reactors and voltage divider. Reactors are dry resin casted type, suitable for different generator
II Main features
l Portable type, very light weight, single part not more than 60kg
l Adopting new frequency-adjusting & inductance-adjusting technology, satisfying requirement of generator power frequency test
l Equipped with 20Hz-300Hz variable-frequency power, strong protection function, good output wave and stability; several working method, convenient operation
l First adjusting inductance, then adjusting frequency, easier to find max. Q point accurately
l Flexible configuration, strong extension function, suitable for both power-frequency test and variable-frequency test; suitable for testing both generators and cables
III Main parameters
l Max. generator capacity: 2000kVA
l Rated output voltage: 0~50kV
