Generator is a one piece complet impulse test equipment, on wheels.
Very easy to test a transformer:
1.) Roll it over to transformer.
2.) Ground the generator.
3.) Connect only 3 wires to transformer: voltage, return (shunt),ground.
On Smart Controller. Dial BIL Set 50%, press HV ON, IMPULSE Few second later.
Set 100%, press HV ON, IMPULSE.
Digitizer recorded every voltage- and current waveforms.
It makes decision go - no go, good or bad the transformer.
