System Grounding: The process of connecting some electrical part of the power system (e.g. neutral point of a star-connected system, one conductor of the secondary of a transformer etc.) to…
Symmetrical Faults on 3 Phase System: Most of the Symmetrical Faults on 3 Phase System on the power system lead to a short-circuit condition. When such a condition occurs, a…
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…
Three Wire DC Distribution System: The great disadvantage of direct current for general power purposes lies in the fact that its voltage cannot readily be changed, except by the use…
Requirements of a Distribution System: A considerable amount of effort is necessary to maintain an electric power supply within the requirements of various types of consumers. Some of the good…
Distribution System Connection: All Distribution System Connection of electrical energy is done by constant voltage system. In practice, the following distribution circuits are generally used 1.Radial System: In this system,…
Overhead vs Underground System: The distribution system can be Overhead vs Underground System. Overhead lines are generally mounted on wooden, concrete or steel poles which are arranged to carry distribution…
