Temporary Partial Discharge Monitoring in Rotating Machines
A variety of stress and aging factors result in partial discharge (PD) activity in rotating machines during their service life, which can cause defects and eventual dielectric failure in the insulation of stator windings.
On-line partial discharge (PD) monitoring provides you with continuous insulation condition status of stator windings while motors and generators are in operation and under the influence of deteriorating forces.
Temporary PD monitoring systems are used to periodically assess PD activity in motors and generators over a specified time. Based on the collected data, you are able to decide if and when it is necessary to schedule downtime and perform maintenance.
These monitoring systems conduct sensitive PD measurements to identify potential defects before failure occurs. Noise suppression and PD source separation algorithms are used to reliably identify harmful PD activity. Warnings and alarms are triggered when user-defined threshold levels are exceeded.
MONTESTO 200 is a portable, two-in-one solution that enables you to perform both temporary on-line partial discharge (PD) monitoring and on-line PD measurements on rotating electrical machines under load, such as motors and generators, to periodically trend PD activity and assess insulation condition over specified periods of time.
Benefits of this solution
Remote data access
MONGEMO is a permanently installed, continuous on-line partial discharge (PD) monitoring system for one or multiple rotating machines, such as generators and electrical motors. It is used for assessing the insulation condition of stator windings and detecting insulation defects by continuously collecting and analyzing PD data over time. The system provides you with detailed PD trend analyses to assess a machine’s insulation state to make timely maintenance decisions.
