IEC 60335-1 Electrical Appliance Testing Equipment 12.5kV 1.2/50μS Or 7kV 10/700μS Impulse Voltages Generator 0
Application:
It is used to verify that the appliances shall withstand the transient over-voltages to which they may be subjected.

 
Test Principle:
The impulse voltage generator with a wave of 1.2/50us(10/700us is optional) is a standard lightning wave test device. The front time of the impulse voltage is 1.2us(10us), the time to half -value is 50us(700us). The impulse voltage test is a destructive test in which a breakdown occurs if the test specimen cannot withstand the applied voltage. When the sample breaks down, sparks and discharge sounds will be generated. The peak voltage of the instrument will drop significantly (close to zero) when it is no-load. When the same voltage is applied again, the above phenomenon will occur.
