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 V
INITIAL
,This product deteriorates
isolation characteristics by partial discharge due to applying high voltage
(ex. V
INITIAL
). And there is possibility that this product occurs partial discharge in
operating isolation voltage (V
IORM
)
