Partial Discharge and High Voltage Testing

HV maintenance testing on a range of assets was undertaken during the scheduled sitewide shutdown at a gas plant.
Following a period of online condition monitoring, where performance degradation had been identified, the decision was made to replace the critical distribution transformer at a gas plant.
An offline Partial Discharge test is becoming standard practise during routine high voltage commissioning of switchgear.
A mine site in NSW, Australia was experiencing reliability issues with their 33 kV cable network
Pinpointing the location of PD on a cable is imperative. LIVE HV’s extensive cable database has proven tolerance levels for
LIVE HV has developed several methods for pinpointing a cable fault without placing any additional stress on the asset.
A pipeline across Queensland comprised of several pumping stations. The machines at six of these pumping stations were monitored, while
In many cases larger HV assets fail testing requirements, or more critically break down in service conditions, due to faulty
Condition assessments of critical assets are integral to maximising their performance and lifespan.
During an online Partial Discharge survey at a Queensland resort, high levels of Partial Discharge were detected while assessing medium

LIVE HV frequently provides On-Line Partial Discharge testing at Windfarms to diagnose and locate cable faults prior to failure.
A large Australian utility asked LIVE HV to PD test their switchgear so that they could identify any areas that required attention.
An Off-Line Partial Discharge test is becoming increasingly popular with Australian Utilities and Industrial Customers during the commissioning of switchgear.
Off-Line cable testing is typically associated with commissioning but it can also be performed during routine outages and is helpful for confirming discharge locations.
Following low Insulation Resistance (IR) readings on a 750m subsea cable, LIVE HV conducted Time Domain Reflectometry (TDR) testing to determine the location of the fault.
