The Rotor Varistor is used to protect the generator electrical unit from voltage surges or transients that can occur due to lightning strikes, switching operations, or other electrical disturbances. It absorbs and dissipates the excess energy caused by these surges, preventing it from damaging the generator's components. It helps regulate the voltage output of the generator by stabilizing the voltage levels during sudden load changes or fluctuations.

Attributes:
• High energy absorption capacity, allowing it to effectively dissipate and divert excessive energy from voltage surges or transients.
• Clamping voltage that is within the acceptable range for the generator's electrical unit

Applications:
The Rotor Varistor provides surge protection, voltage regulation, transient suppression, and protection of sensitive components. It ensures the safe and reliable operation of the generator's electrical unit.
