SEL relays detect faults and other abnormal conditions in electric power systems and initiate protective actions to maintain system stability and safety. They are used in a wide range of applications, from transmission and distribution to industrial power systems. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function.

Feeder protection relays are vital devices that protect power system feeders from various types of faults. They can improve power system reliability, security, and efficiency by quickly detecting and isolating faults, preventing damage to equi. It measures the feeder line's impedance (Z) using voltage (V) and current (I) inputs from the potential transformer (PT) and current transformer(CT). A quadrilateral characteristic is a parallelogram-shaped graph that defines the protection z.

The standard specifies transmission convergence layer, physical layer requirements, management protocols, and service encapsulation for high-speed fiber access networks. GPON puts requirements on the optical medium and the hardware used to access it, and defines the manner in which Ethernet frames are converted to an optical signal, as well as the parameters of that signal. GPON replaces the traditional three-tier Ethernet design with a two-tier optic network which eliminates access and distribution Ethernet switches with passive optical devices. This document describes the Gigabit Passive Optical Network (GPON) technology and how it functions. It is commonly used to implement the link to the customer (the last kilometre, or last mile) of fibre-to-the-premises (FTTP) services, using a.
