IEC 61851 High Voltage Impulse Test Generator for EV Charging Equipment
IEC 61851 High Voltage Impulse Test Generator for EV Charging Equipment
Complied Standards & Clauses
The Impulse Test Generator conforms to the standard requirements of IEC 61851-1 clause 12.7, IEC 61851-23 clause 11.4, etc.
Equipments Overview
It is used to verify that the appliances shall withstand the transient over-voltages to which they may be subjected. 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.
