- 6. GIS • Definition:- A Gas Insulated Substaion is a Substation that use a superior dielectric gas,Sulfur Hexafluoride(SF6),High Voltage. • The Basic Principal of GIS Equipments:- • Is that high-voltage current carrying parts are within a metal enclosure and are held in a concentric configuration by cast epoxy spacer insulators. • The Space between the conductor and the enclose is filled with SF6 gas under moderate pressure. Gas Insulated Substation

- 10. • In The Single Phase enclosed core of CT isolated the enclosure inside for these Phase. • Gas Compartment to reduce access of moisture and to suppress gas, high boshing for Secondary connections. • CT Current rating is 120% of Rated Primary Current. • Voltage Transformer:- • Variable location in feeder and bus bar. • Intergrated diconnecting facility for GIS and power cable testing without dismantling and gas handling. • Current Transformer:-
- 11. • Disconnectors or isolators are used for electrical isolation of circuit parts. • Disconnected switches can be three pole, group operated or single pole operated. • They are slow acting and operating at off load. • Earth Switch:- • Slow operating earthing switch are used for protection purpose. • When work is baing done in the substaion, but are operated only energized. • The fast closing earthing switch can close against full voltage and short circuit power. • The high speed earthing switch is achieved by means of a spring-closing device. • Disconnector:-
- 12. • Circuit Breaker:- • Under short circuit conditions however the current may reach tens of thousands of amperes at a power factor as low 0.1. • Its is duty of a circuit breaker to interrupt such currents as soon as possible to avoid equipment damage. • Bus-Bar:- • An electrical conductor that carries a large current especially one that is part of a power distribution on system typically a thick strip or a tube of copper or aluminum. • Wave Trap:- • Is a device that is used to block communication signals from passing through it and only allows power signal to pass through it, • The wave trap acts as a filtering cum protective device that filters the high frequency signal to low frequency signal and give protection against surge voltage.
