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. […]

Types of Protective Relays

Types of Protective Relays: Basically, Types of Protective Relays are analogue-binary signal converters with measuring functions. The variables such as current, voltage, phase angle or frequency and derived values obtained by differentiation, integration or other arithmetical operations, appear always as analogue signals at the input of the measuring unit. The output will always have a […]
