Customer Feedback

 

 

What needs to be taken into account when testing protection relays?

When testing protection relays, the number one priority is your own safety. When preparing to test protection relays, all relevant safety and protection measures must be adhered to before testing commences.
 

Aspects of protection relay testing

1.    Visual assessment of the relay's condition
2.    Verifying the wiring after commissioning or rewiring
3.    Testing and matching of the protection relay's  parameters with the predefined requirements
4.    Verifying the relay's functionality through testing of the individual protection functions
5.    Checking whether the pick-up and trip time values are within the defined limits
6.    Verification of the relay behavior from a system perspective
