Application

The equipment can be operated as power source to simulate the over-voltage/current as it is occurred in the system.

This equipment is mainly used for SPD TOV test caused by the failure in voltage system. It can be also used in other scientific research.


Standard

IEC61643.11-2011, GB18802.1-2011, other national

standards and customer specified
