Continuous Online Partial Discharge Monitoring of High Voltage Transformers
Application: Partial Discharge Monitoring
A Partial Discharge (PD) is a small electrical spark that occurs within the electric insulation of switchgears, transformers, and windings in large motors and generators. Partial Discharge Analysis is a proactive diagnostic approach that uses PD measurements to evaluate the integrity of this equipment. PD results are used to reliably predict which electrical equipment is in need of maintenance.
In the past, offline PD measurement techniques have been widely used to detect potential future failures. However, offline techniques are time consuming and require network outages, which present an operational risk. Online measurement techniques present no such issues, and they provide a continuous monitoring capability. The online monitoring techniques that are now available have the potential to offer easy, cost-effective solutions and, most importantly, to detect the onset of incipient failures on cables/transformers/switchgears with a previously good reliability record.
