The main group of impedance relays is distance protection devices. loss of synchronism protection, loss of excitation protection, or impedance automatics like fault locator. Impedance Relay Definition: An impedance relay, also known as a distance relay, is defined as a device that triggers based on the electrical impedance measured from a fault's location to the relay. Working Principle: The operation of an impedance relay hinges on the balance of voltage-induced. When a system has too many radial lines protection using time delay overcurrent relay becomes impractical. This problem can be solved to an extent by using distance relays. Distance relays uses voltage and current to calculate the. Distance relay protection has been defined as a part of relay protection in power systems that detects and isolates faults based on the distance between the relay and fault points. Unlike overcurrent relays, which only respond to the magnitude of current, a distance relay measures the impedance of. Such relays are called Distance Relays or Impedance Relays. In an impedance relay, the torque produced by a current element is opposed by the torque produced by a voltage element. The relay will operate when the ratio V/I is less than a predetermined value. The voltage transformer measures the voltage across the protected equipment, while the current transformer measures the current flowing through it.
