Partial Discharge Measurement and Monitoring
Partial discharge (PD) is considered one of the major contributors to the degradation and failure of insulation systems in electrical equipment.
Compared to other dielectric diagnostic methods, off-line PD measurement and analysis and on-line PD monitoring allow you to effectively and reliably assess the insulation condition of a number of high-voltage assets at a particular point in time and throughout the service life of electrical equipment.
To detect and localize insulation defects and assess risks of equipment failure, off-line PD measurement and analysis are performed during factory acceptance, on-site commissioning and routine maintenance testing. On-line PD monitoring is performed over longer periods of time when the equipment is in service to track the development of PD activity and determine when it poses a risk to equipment reliability.

Off-line Partial Discharge Measurement and Analysis
Compared to other dielectric diagnostic methods, off-line PD measurement and analysis allow you to effectively and reliably assess the insulation condition of a number of high-voltage assets. They are performed during factory acceptance, on-site commissioning and routine maintenance testing to detect insulation defects and assess risks.
Since PD activity is often present well in advance of insulation failure, PD measurement and analysis allow you to make informed decisions regarding the timely repair or replacement of equipment to ensure operation reliability.

On-line Partial Discharge Monitoring
On-line PD monitoring systems allow asset managers to continuously collect a vast amount of information without interrupting normal service. These PD monitoring systems continuously record insulation condition data and trend PD activity under real load conditions while electrical equipment is in service. PD activity can either be continuously monitoring on a periodic or permanent basis.
Based on the collected data, you can determine when electrical equipment requires maintenance or replacement based on insulation condition status.
