Protective Relaying
The protective relays act only after an abnormal or intolerable condition has occurred, with sufficient indication to permit their operation.

AC Surge Protection
Not only is the electronic equipment more sensitive from outside transients, but their power supplies generate high frequency noise that will hurt other electronic equipment tied to the same power bus.

Relay protection of the main grid and customer connections
To maintain stability, all short-circuit faults in the 400 kV power grid are separated by means of a relay protection no later than 0.1 seconds after the start of the fault.

Protective relay
The need to act quickly to protect circuits and equipment often requires protective relays to respond and trip a breaker within a few thousandths of a second. In some instances these clearance times are
