Summary of PD Test and Monitoring Products
- Portable PD 'Survey' and 'Diagnostic Spot Test' Technology, including the HVPD Longshot™ Diagnostic Online PD Spot Tester (suitable for the online PD testing of all types of mv and hv cables and plant up to 500kV) and the PDSurveyor™ handheld PD surveying tool - the world's first, handheld, multi-purpose, PD 'screening' test unit (suitable for the online PD testing of mv cables and plant in the voltage range of 6.6kV to 45kV).
- Portable PD Monitoring Technology, including the HVPD Mini™ Portable Monitor and the HVPD-Multi™ Portable monitor systems which have been designed for short to medium term PD monitoring installations (of between 1 day up to 3 months) of mv cables and plant. Both monitors incoporate 3G mobile communications technology (GPRS and HSDPA) for remote download of PD monitoring data with all data.
- On-line MV and HV Cable Mapping, expansion system for the HVPD Longshot™ Spot Tester to enable on-line cable PD location on mv and hv cables of up to 5km in length.
- Permanent PD Monitoring Technology including the HVPD Permanent Mini Monitor™ and the HVPD Permanent Multi Monitor™ PD monitor systems (suitable for long-term PD monitoring of 3 months+ of mv cables and plant. Both of these permanent monitors can be connected to LAN or Modbus plant management systems for real-time, continuous data PD monitoring.
