What does the exciter field voltage meter indicate?

The exciter field voltage meter indicates the DC voltage supplied to the generator's field windings. This measurement is crucial because the voltage applied to the field windings directly affects the strength of the magnetic field generated within the generator. A stronger magnetic field increases the generator's output voltage and enhances its efficiency in converting mechanical energy to electrical energy.

Monitoring the exciter field voltage ensures that the generator operates within its designed parameters. If the voltage is too low, the output may be insufficient to meet demand, leading to underperformance. Conversely, if the voltage is too high, it can cause overheating and damage to the winding insulation. Therefore, understanding this meter's reading allows operators to maintain optimal performance and prevent potential system failures.
