value of the test voltage to be applied under specified conditions in a withstand test, during which a specified number of disruptive discharges is tolerated
Note – The withstand voltage is designated as:
a) conventional assumed withstand voltage, when the number of disruptive discharges tolerated is zero. It is deemed to correspond to a withstand probability PW = 100 % (this is in particular the case in the low-voltage technology);
b) statistical withstand voltage, when the number of disruptive discharges tolerated is related to a specified withstand probability, for instance PW = 90 %. |
