  • Design Principles of Fiber Optic Communication Networks

    Design Principles of Fiber Optic Communication Networks

    Fibre optic network design is the structured engineering process of planning how optical fiber infrastructure connects buildings, campuses, cities, and regions. It includes determining the type of communication system(s) which will be carried over the network, the geographic layout (premises, campus, outside plant. According to ResearchAndMarkets, the global market for fiber optics was estimated at $5. 8 billion in 2022 and is expected to reach $11. This is the dominant broadband access technology across half of OECD countries today.

  • Relay Protection Principles in Everyday Life

    Relay Protection Principles in Everyday Life

    Differential Relay: Compares currents at two points; operates when there is a difference (used in transformers and generators). Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. Protective relays using electrical quantities are connected to the power system through current transformer (CT) or voltage transformer (VT). What controls it: Relay performance depends on the protected zone, CT/PT inputs, pickup settings, time delay, breaker clearing time, trip. The relays are in round glass cases. A protective relay is a device that monitors system conditions like amps, volts, etc.
