Effective assessment of partial discharge activity in the stator windings ensures safe and reliable operation of rotating machine. Partial discharge can occur at single or multiple locations inside stator windings due to many reasons such as dust, looseness in end windings, voids etc. By analyzing the partial discharge data we can assess the risk and plan for maintenance accordingly.
By monitoring partial discharge characteristics, the operational reliability of the insulation in critical machines can be assessed on real-time basis. And it helps generate valuable information for maintenance planning and repairs when they are required. Or in many cases PD assessment can help avoid or postpone the inspection and maintenance plans to prioritize the operational availability of the assets.
The detection of partial discharge activity can be done either periodically or through continuous monitoring.
- Partial discharge detector for periodical measurement
- Partial discharge analyzer for continuous monitoring
