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…
Booster Generator: A Booster Generator is a D.C. generator whose function is to inject or add certain voltage into a circuit so as to compensate the IR drop in the…
Three Wire DC System Balancer Set: Although in a 3-wire d.c. system every effort is made to distribute the various loads equally on both sides of the neutral, yet it…
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…
Grading of Cables: The process of achieving uniform electrostatic stress in the dielectric of cables is known as grading of cables. It has already been shown that electrostatic stress in…
Classification of Underground Cables: Classification of Underground Cables may be in two ways according to the type of insulating material used in their manufacture the voltage for which they are…
Insulating Materials for Underground Cables: The satisfactory operation of a cable depends to a great extent upon the characteristics of insulation used. Therefore, the proper choice of Insulating Materials for…
