How to Address Partial Discharge in Generators

Recently, one of our clients raised an important question: How should they respond to the presence of partial discharge identified during a recent generator inspection? At CRYSOUND, we understand the significance of this challenge and are here to provide valuable insights.

Partial discharge is a phenomenon that cannot be completely eliminated from high-voltage motors and generators. However, it is crucial to closely monitor and address partial discharge, as it can impact the performance of insulating materials.

In the power industry, inspectors rely on observing the working status and performance of motors by studying the trend of partial discharge intensity in the generator.

If the intensity of partial discharge in the generator shows an upward trend, it indicates a potential issue within the generator. At this point, it becomes necessary to analyze the underlying cause of this phenomenon and conduct a thorough examination of the motor's functionality.


By taking proactive measures to address partial discharge, our clients can ensure the reliability and longevity of their generator systems. CRYSOUND's Acoustic Imager has proven to be an effective tool in detecting suspension discharge and surface discharge, assisting our clients in identifying and resolving potential problems early on.


The CRYSOUND Acoustic Imager enables inspectors to analyze the intensity of partial discharge in the generator and closely monitor the functionality of the motors, thereby ensuring the safety of the environment.
