Real-Time Online Monitoring to Detect and Analyze Potential Partial Discharge (PD) Signals and Insulation Faults using UHF, AE, and HFCT
PDMonitor
Power Monitoring and Diagnostic Technology Ltd.
The PDMonitor, which utilizes Ultra High Frequency (UHF), Acoustic Emission (AE) and High Frequency Current Transformer (HFCT) sensors and is designed to conduct real time online monitoring to detect and analyze potential Partial Discharge (PD) signals and insulation faults before they lead to breakdown or catastrophic failure in power assets. The system provides the developing trend of the PD, when occurring, as alarms in real time, thus helping to predict the insulation degradation status of the asset, prevent sudden accidents, and provide an effective database for Condition-Based Maintenance (CBM) of power assets.
