Answer 1

Answer:

The voltage regulation of an alternator is defined as the change in its terminal voltage when full load is removed, keeping field excitation and speed constant, divided by the rated terminal voltage.

• The value of the regulation not only depends on the load current but also on the power factor of the load.
• For lagging and unity p.f. conditions there is always drop in the terminal voltage hence regulation values are always positive.
• While for leading capacitive load conditions, the terminal voltage increases as load current increases. Hence regulation is negative in such cases.
• The relationship between load current and the terminal voltage is called load characteristics of an alternator.
