When neither the compensating winding nor pressure wires are used, there will be no "over compounding" effect due to increase of load and a constant voltage will be maintained at the bus bars.
The pressure wires take the place of the leads from the control magnet to the bus bars and maintain a constant voltage at the center of distribution.
With a constant speed at the motor and its connected generator it is of course easy to deliver current at constant voltage to the distribution lines.
Automatic regulators are used in some generating stations to maintain a constant voltage either at the generating terminals or at some distant distributing point on a line operated by a single generator.
If the torque be insufficient for the load, the speed will diminish until equilibrium is established, assuming the motor is running on constant voltage circuit.
If the motor be run on a constant voltage circuit, with light load, it will run at a very high speed; again, if the motor be loaded heavily, the speed will be much less than before.
The speed of motors connected to constant voltagecircuits is usually regulated by the two following methods: [Illustration: FIG.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "constant voltage" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
