What Is A Directional Power Relay at Hayley Forster blog

What Is A Directional Power Relay. The relay sense the fault current in only one direction, the relay does not operate when the current in opposite direction. When the power in the circuit flows in the normal direction, the driving torque and the restraining torque (due to spring) help each other to turn away the moving contact from the fixed contacts. The reference voltage is called polarising voltage. Directional relay measures phase angle between voltage and current. This is the voltage taken from potential transformers. In order to achieve the operation of the relay in the forward direction, a directional feature is added to the overcurrent relay by adding a directional relay to the overcurrent relay, such a. To define the zone and the power flow, each relay has two inputs (dfin and dbin: Directional feature is realized by comparing the direction of flow of line current with reference to the bus voltage i.e. Directional earth fault relay is used to protect the transformer/generator/alternator from over current fault. Directional forward in and directional backward in) and two. Directional relays needed reference voltage to identify the direction of currents. Consider a typical electromechanical phase directional relay.
