Applications in High Voltage Bushings: At rated voltages higher than 52 kV, the condenser or capacitance graded bushing principle is generally used. The insulating material for such a Applications in…
Grounding or Earthing: The process of connecting the metallic frame (i.e. non-current carrying part) of electrical equipment or some electrical part of the system (e.g. neutral point in a star-connected…
Protective Relay: A Protective Relay is a device that detects the fault and initiates the operation of the circuit breaker to isolate the defective element from the rest of the…
Sequence Networks Unsymmetrical Faults: The analysis of an unsymmetrical fault by symmetrical components method can be conveniently done by drawing sequence networks. A Sequence Networks Unsymmetrical Faults of a particular…
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…
Brown Boveri Regulator: In this type of Brown Boveri Regulator, exciter field rheostat is varied continuously or in small steps instead of being first completely cut in and then completely…
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…
