For three phase circuits three regulators can be used, one on each phase, or they can be furnished in pairs with an auxiliary auto-transformer to give a balanced load.
As shown, the primary winding ofeach phase is divided into three coils to ensure better insulation.
After ½ cycle when the current in each phase reverses, the pole advances the angular distance, covered by two groups; hence the field completes one revolution in eight alternations of current.
Into the two brass cylinders of each phase dips a ∩-shaped contact piece through insulating bushings, and the ends of this contact piece fit into terminals at the bottom of the oil pots.
In each of these switches the two leads of each phase terminate in two upright brass cylinders.
One end of each phase winding is connected by the brushes a and b', to one of the circuit wires, that is to A and B respectively.
A wire is connected to both ends of each phase winding, giving six conductors, or three independent two wire circuits.
The other end of each phase winding is connected by a lead across brushes a' and b, to which the third wire C is joined.
A wire is connected to one end of each phase winding as at A and B, and a third wire C, to the other end of both phases as shown.
The voltage of all the phases should be observed for normal full load excitation by connecting the voltmeter to each phase successively, keeping the field current constant at normal voltage.
It will further be seen that in order to express the composition of each phase present, two of these constituents are necessary.
Inductors A, B, and C, the beginning of each phase winding, are lettered to correspond with fig.
The coils of each phase are of the partially distributed type, each coil being made up of three sections as shown.
The current in each main is obviously equal to the current in each phase winding, but the terminal pressure is the vector sum of the pressures in the component phase windings, that is, √3̅ multiplied by the pressure in one phase.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "each phase" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
