Reducing Electrical Risk with Partial Discharge Insights for Water Utilities
)
Key outcome
A major Australian water utility engaged our experts to carry out partial discharge (PD) testing across critical 11kV electrical infrastructure supplying a large water treatment operation. The objective was to gain greater visibility of hidden insulation risks, improve network reliability and explore how continuous PD monitoring could support a more proactive maintenance strategy.
Electrical infrastructure in water treatment facilities operates continuously in demanding environments where reliability is critical. Hidden insulation defects can remain undetected for years before resulting in:
Unplanned outages
Equipment failure
Safety incidents
Operational disruption
Increased maintenance costs
The utility wanted to:
Assess the condition of key high-voltage assets without taking systems offline
Identify whether any PD activity was present across the network
Establish a benchmark for future condition trending
Understand the feasibility of continuous PD monitoring on long HV feeder systems
