Single-fiber bidirectional line protection
BD OLP, also known as BIDI OLP or single-fiber bidirectional 1+1 OLP, is an optical line protection method designed for situations where fiber resources are extremely limited. The system monitors the working optical fiber and a standby fiber in real time, detecting when the working path falls below a threshold. Designed for both cascaded and hub-and-spoke network topologies, the system ensures recovery from a single fiber cut in a ring. Traditional OLP protects 4-core optical fiber, but in many places, due to insufficient optical fiber resources, it is impossible to provide excessive optical fiber resources and optical line redundancy protection. Optical Line Protection System (OLP) is an automatic monitoring and protection system which is independent of telecommunication transmission.

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.
