Classification of Transmission Line Relay Protection
Distance Relay: Operates based on impedance, commonly used in transmission line protection. Earth Fault Relay: Detects leakage currents to the ground. Frequency Relay: Trips when frequency. Transmission lines act like the arteries in the human circulatory system, moving electrical power from were it is produced by generators to where it is consumed at load centers. And like arteries in the human body, the loss or damage to transmission infrastructure can have disastrous effects on the. Core idea: Transmission line protection detects faults and trips the correct breakers so the faulted line section is removed without unnecessarily de-energizing healthy equipment. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. Differential Relay: Compares currents at two points; operates when there is a difference (used in transformers and generators). In 400/220/132 KV line, all above protection are provided.
