Online Partial Discharge Monitoring of Rotating Electrical Machines
The performance and reliability of rotating electrical machines are critical for power generation and running critical processes in industrial applications. However, performance and reliability can be compromised over time due to the thermal, electrical, ambient and mechanical stresses motors and generators are continuously subjected to when in operation.
Partial discharge (PD) activity is an indication of weak spots in the insulation that can cause failure and damage to motors and generators and can be continuously monitored over time, either on a temporary or permanent basis, to efficiently plan maintenance and prevent failure.

Temporary Partial Discharge Monitoring in Rotating Machines
Temporary partial discharge (PD) monitoring systems are used to periodically assess PD activity in motors and generators over specified periods of time. It provides you with continuous insulation condition status of stator windings while motors and generators are in operation and under the influence of deteriorating forces. Warnings and alarms are triggered when user-defined PD threshold levels have been exceeded, so that you can diagnose the situation with off-line PD measurements and plan timely condition-based maintenance.

Permanent Partial Discharge Monitoring in Rotating Machines
Permanent partial discharge (PD) monitoring systems are used to assess developing PD activity over the entire service life of single or multiple motors and generators in your fleet. Warnings and alarms are triggered when user-defined PD threshold levels are exceeded. Through trended PD activity and assessment of insulation condition over time, you can decide if and when it is necessary to schedule downtime and perform maintenance to prevent pre-mature machine failure.
