During a short interruption the voltage is zero; thus, there is no supply of power at all to the equipment.…

As short interruptions are due to automatic switching actions, their recording requires automatic monitoring equipment. Unlike long interruptions, a short…

Switchgear covers a wide range of equipment concerned with switching and interrupting currents under both normal and abnormal conditions. It…

The essential features of switchgear are: (I) COMPLETE RELIABILITY With the continued trend of interconnection and the increasing capacity of…

The apparatus used for switching, controlling and protecting the electrical circuits and equipment is known as switchgear. The switchgear equipment…

An induction regulator is essentially a constant voltage transformer, one winding of which can be moved w.r.t. the other, thereby…

When the load on the supply system changes, the terminal voltage of the alternator also varies due to the changed…

In this type of regulator, exciter field rheostat is varied continuously or in small steps instead of being first completely…

In this type of regulator, a fixed resistance is cut in and cut out of the exciter field circuit of…

WHAT IS VOLTAGE CONTROL? In a modern power system, electrical energy from the generating station is delivered to the ultimate…
