Abstract: Protective relays and devices have been developed over 100 years ago to provide "last line" of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the
The protective relays act only after an abnormal or intolerable condition has occurred, with sufficient indication to permit their operation.
Protective relays are usually expected not to operate during normal operating conditions, but must immediately respond to handle intolerable disturbances in power networks. This immediate
