Introduction to gas insulated switchgear and substations.
This article is an introduction to gas insulated substations.
They transform the.
Introduction substations are an important part of the electrical distributions.
A compact multicomponent device enclosed in agrounded metallic case in which the basic insulating medium is sf6 gas and which icallytyp includes buses switches circuit breakers.
Gas insulated switchgear gis complete portfolio for all applications and environments gas insulated high voltage switchgear gis is a compact metal encapsulated switchgear consisting of high voltage components such as circuit breakers and disconnectors which can be safely operated in confined spaces.
Require more space than gas insulated substations.
Gas insulated substation gis design.
Since its introduction back in 1968 siemens has installed switch fields in all climatic zones of the earth recording over 420 000 years of operation since.
This course will attempt to provide an in depth understanding of gas insulated substations gis including design construction operations and maintenance.
A switchgear may be a simple open air isolator switch or it may be insulated by some other substance.
A gas insulated substation gis is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as sf6 or sulfur hexafluoride gas as the insulating medium.
An effective although more costly form of switchgear is the gas insulated switchgear gis where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas sf 6.
Gas insulated substation gis also called sf6 gas insulated metalclad switchgear is preferred for 12kv 36kv 72 5kv 145 kv 245 kv 420 kv and above voltages.
Due to the gas enclosed design gis is the most suitable solution for indoor and underground substations.
This course provides an brief introductory overview of gis or gas insulated substations.
Other common types are oil or vacuum insulated switchgear.
Gas insulated substations ge provides a full range of gas insulated substations gis for utilities and industries worldwide.
Attendees will gain a perspective from both an original equipment manufacturer oem and utility on the lifecycle journey to a gis installation including costs and long term roi.
The portfolio includes gis solutions from 60 to 800 kv along with secondary products to maximize switchgear and network operation.
The siemens range of gas insulated switchgear gis for rated voltages from 72 5 kv up to 550 kv is an extremely successful product concept.
