Cautions:
When there’s current get through the primary winding of current transformer, the secondary winding shouldn’t be open circuit; otherwise there would be high voltage generated, which is harmful or have impact on personal security and product performance.
Repeated power frequency voltage-withstand test, should be taken at the 85% of stipulated test voltage value.
