Gases and Gas Mixtures for Insulation Purposes: Over the years, considerable amount of work has been done to adopt a specific gas for practical use. Before adopting a particular gas…
Oil Circuit Breaker Diagram: In such Oil Circuit Breaker Diagram, some insulating oil (e.g., transformer oil) is used as an arc quenching medium. The contacts are opened under oil and…
Circuit Breakers Definition: A circuit breaker can make or break a circuit either manually or automatically under all conditions viz., no-load, full-load and short-circuit conditions. This characteristic of the Circuit…
Bus Bar Arrangement in Power Station: When a number of generators or feeders operating at the same voltage have to be directly connected electrically, bus-bars are used as the common…
Induction Regulators: An induction regulators is essentially a constant voltage transformer, one winding of which can be moved w.r.t. the other, thereby obtaining a variable secondary voltage. The primary winding is…
Capacitance of 3 Core Cables: The Capacitance of 3 Core Cables is much more important than that of overhead line because in cables (i) conductors are nearer to each other…
Laying of Underground Cables: The reliability of Laying of Underground Cables network depends to a considerable extent upon the proper laying and attachment of fittings i.e., cable end boxes, joints,…
Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the…
