Protection of Transformers: Transformers are static devices, totally enclosed and generally oil immersed. Therefore, chances of faults occurring on them are very rare. However, the consequences of even a rare…
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…
Tap Changing Auto Transformer: Fig. 15.6 shows diagrammatically Tap Changing Auto Transformer. Here, a mid-tapped auto-transformer or reactor is used. One of the lines is connected to its mid-tapping. One…
Tap Changing Transformers: The excitation control method is satisfactory only for relatively short lines. However, it is not suitable for long lines as the voltage at the alternator terminals will…
