ydeepak297@gmail.com Major Equipment’s of Electrical Substation Transformer, circuit breaker and interrupter are the major equipments in the traction substation. They are discussed below in detail. Transformer :- Transformer is the major component of traction substation. Normally, step down transformer is used to step the high voltage level from 220kV – 132kV to a working voltage level … Read more
What is Sag “is sag a necessity or evil” Discuss. The straight distance between the two poles gives the shortest distance. Therefore to minimize the length of conductor, one may stretch the conductor to make it straight. However if the conductor is stretched too much, beyond its safe value, then conductor may break due to … Read more
Span Lengths of Electrical Transmission Line The distance between the two adjacent poles is known as span length. It is generally denoted by ‘l’ (L) and specified in meters. The location of the supports (towers) depends upon the profile of the land along which transmission line is to be run. This means the span length … Read more
Construction of Electrical Underground Cable Components of Cable Conductors Insulation Metallic sheath Bedding Armouring (Mechanical protection) Serving (1) Conductors Conductors used for cables are generally made up of tinned copper or aluminium. To provide the sufficient flexibility conductors are used in stranded form. Cable may consists of one, two, three or four conductors depending upon the … Read more
