Precautions in performing isolation test
* Partial discharge test methods shall be the ones according to the specifications of DIN EN 60747-5-5
* Please don't carry out isolation test (Viso) over VINITIAL ,This product deteriorates
isolation characteristics by partial discharge due to applying high voltage
(ex. VINITIAL ). And there is possibility that this product occurs partial discharge in
operating isolation voltage (VIORM)
