Characteristic Functions of Protection Relay

Characteristic Functions of Protection Relay: Characteristic Functions of Protection Relay elements using different operating principles. These principles and design criteria determine how well the basic function is performed and how in practice it deviates from the ideal. Static relays can achieve such a high performance that the departures from the ideal in practice are negligible. […]

Static Relay

Static Relay: The term ‘static relay’ is generally referred to a relay incorporating solid state components like transistors, diodes, resistors, capacitors, etc. In this type of relay, the functions of comparison and measurement are performed by static circuits wherein there are no moving parts. Accord­ing to a recent decision of the International Electrotechnical Commission (IEC), […]
