Generation of Alternating Voltage

The voltage which changes polarity at regular interval of time is known as the alternating voltage. The one complete cycle of an alternating quantity consists two half cycles. And the direction of a half cycle changes after every particular interval of time. The machine which generates the alternating voltage is known as the alternator. The …

Star Connection in a 3 Phase System

In the Star Connection, the similar ends (either start or finish) of the three windings are connected to a common point called star or neutral point. The three-line conductors run from the remaining three free terminals called line conductors. The wires are carried to the external circuit, giving three-phase, three-wire star connected systems. However, sometimes …
