HVPD’s unique condition monitoring (CM) solution provides an early warning of incipient High Voltage (HV) insulation faults across the complete network, helping operators to avoid unplanned outages.
The knowledge of the fault severity and source within the network is crucial for the operator to avoid unexpected downtime and lost output, which can cost hundreds of thousands of pounds per day. The cost of the system pays back immediately when a single critical failure is prevented through the continuous benchmarking of condition monitoring data.
HVPD’s complete HV network On-line Partial Discharge (PD) monitoring solution involves distributing On-line PD sensors and monitoring nodes at strategic locations across the HV network with different On-line PD sensors and monitor configurations applied depending on the HV asset to be monitored.
This unique solution from HVPD incorporates one patented CM module and two patent-pending CM modules to enable the continuous On-line PD monitoring of complete HV networks including transformers, cables, switchgear, motors and generators. The patented CM module provides for the remote PD monitoring of direct-fed Ex/ATEX (Hazardous Gas) HV motor circuits.
A second patent-pending solution for the reliable On-line PD monitoring of VSD-operated Ex/ATEX HV motors is combined with a third CM module that provides On-line PD monitoring coverage for transformers, generators cable circuits and switchgear.
These three technologies are combined into a complete HV network monitoring system with data passed via LAN to a PD monitoring server (PDMS) located at the control room of a facility with secure remote data access to provide data analysis, benchmarking, trending and reporting through a graphical user interface (GUI) ‘mimic’ of the power network’s single-line diagram (SLD).
