Feeder Protection Relay: A Comprehensive Guide
A common type of feeder protection relay is the distance protection relay, also called an impedance relay. It measures the feeder line''s impedance (Z) using voltage (V) and current (I) inputs
Types of Protective Relays
The power line carrier is the most commonly used pilot for protective relaying. In this type of pilot, a low-voltage, high-frequency current (30 to 300 kHz) is transmitted along one phase of the high-voltage
