Protection of Alternators and Transformers Articles: Protection of Alternators: The generating units, especially the larger ones, are relatively few in number and higher in individual cost than most other equipment’s.…
Transformers Articles: How does a Transformer Work and Purpose of Transformer: How does a Transformer Work – A Transformer Circuit is a static device comprising coils coupled through a magnetic…
Cascade Transformer Connection: Figure 6.10 shows the Cascade Transformer Connection units in which the first transformer is at the ground potential along with its tank. The second transformer is kept…
Voltage Transformer Earthing: In this method of neutral earthing, the primary of a single-phase Voltage Transformer Earthing is connected between the neutral and the earth as shown in Fig. 26.17.…
Equipments in Transformer Substation: The Equipments in Transformer Substation depends upon the type of sub-station, service requirement and the degree of protection desired. However, in general, the Equipments in Transformer…
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…
Booster Transformer: Sometimes it is desired to control the voltage of a transmission line at a point far away from the main transformer. This can be conveniently achieved by the…
