Question

please make it more understanding and more specific. tq

4. Tabulate at least five protections of all components of power system e.g. Generator, Transformer, Busbar, Transmission/Sub-Transmission, Motor Load. 5. Furnish a table for the names of the protection relays and their respective numbers in accordance with standard like IEEE, IEC, and ANSI as tabulated at 4. Furnish a one-line diagram to show at least three protections enlisted (in table) at 4 with their respective variable quantities (inputs and outputs). 6.

Answer 1

Solution - Ф © we are required to write at least five protection equipments for generator Hoverspeed protection → Reverse power protection stator earth fault protection Over Current Relays -> Thermal Overload protection Inter form fault protetion Transformer ~ diffential protection → Buchholz protection → over flexing protection + overlapping protection & Restricted earth fault protection yover current protection

Busbar lo → Reverse blocking → diffential protection → over current protection y frame earth protection phase comparison protection Transmission over coment Relay diffemtial pilot wire protection. 7 split conductor protection merly piece protection Translay protection + Overload protection impedence directional relay motor load tover voltage protection - thermal Reverse motor → under voltage protection - single phasing protection → Earth fault protection. protection swing protection
