LORD Power Equipment and HVPD UK are upbeat about the potential contribution of the HVPD "MiniTM Monitor" continuous on-line partial discharge monitor to cable and switchgear assessment.
To assist with this process, HVPD have focussed the configuration of the Mini-Monitor to permit cost-effective remote logging of up to 4 channels of data (2 for cable PD, 2 for switchgear PD) via an integrated GPRS 3G module. Not only does the device permit the confirmation of PD severity and trend, a unique precedence detection algorithm has been integrated which, along with associated software, can allow multiple such units to confirm remotely the location of the discharge in complex interconnected networks. HVPD complement the Mini-Monitor with an innovative spectrum of associated PD equipment, ranging from simple hand-held pre-qualification devices for cable and switchgear PD, to sophisticated computer-assisted survey devices capable of doing on-line PD location in cables and switchgear. HVPD's unique analysis packages for PD assessment in high voltage switchyards and HV assets in general is proving of great interest to the Australian transmission market presently.

Having identified significant levels of PD on an asset, the main interest then is the qualification of the discharge with load over time and thence, if concerning, the keeping of a watching brief if PD levels indicate a worsening trend.
