Why is the neutral wire in housing circuits also at zero potential (in addition to earth wire which is also at zero potential)?© BrainMass Inc. brainmass.com October 9, 2019, 10:48 pm ad1c9bdddf
A three phase AC generator has three separate windings displaced from each other by 120^O. The voltages induced in the three windings are, therefore, out of phase with each other by 120^O. These three windings can be connected to each other as shown in the fig (see attachment) known as star connection, to supply three phase power (they can also be connected in what is known as delta connection which we will not discuss here). The three ...
