Powerex Services provides high voltage maintenance and operations support for substations and other facilities that don’t have in-house capability, or require an independent third party to manage switching, maintenance, and ongoing asset care.
Planned maintenance is critical for monitoring the condition of high-voltage equipment and preventing failures before they occur. It reduces the risk of unplanned outages, protects critical assets, and supports compliance with insurance and regulatory requirements. Most importantly, it keeps sites operating reliably and avoids the cost and disruption of uncontrolled downtime.
We also provide practical advice on maintenance strategies and forward planning, including when assets should be repaired, retrofitted, or upgraded, so you can make informed decisions before failures force your hand.
Routine electrical testing to verify insulation condition, protection performance, and overall equipment health, helping identify issues early and reduce the risk of failure.
Removal of dust, debris, and contamination that can compromise insulation, mechanical operation, and long-term reliability of high-voltage equipment.
Sampling and analysis of insulating oils to assess condition, detect contamination or degradation, and inform maintenance or replacement planning.
Detailed visual inspections to identify signs of wear, damage, overheating, corrosion, or abnormal operation before they escalate into faults.
Planned, condition-based maintenance programs designed to reduce unplanned outages, improve reliability, and extend asset life while supporting compliance and insurance requirements.
It’s common knowledge that ageing high-voltage equipment is more prone to failure. However, equipment when energised often sits idle for long periods of time and can become just as problematic when the time comes to operate.
When high-voltage assets aren’t operated or maintained regularly, issues such as moisture ingress, dust accumulation, insulation degradation, and seized mechanisms can go unnoticed. Without routine operation, inspection, and preventative maintenance, equipment condition can deteriorate silently. Regular testing and maintenance identifies these risks early, reducing the likelihood of unexpected failures, uncontrolled outages, and costly emergency repairs.
Between our Directors, we bring 30 years of high-voltage experience. That experience shows up in how we plan work, identify risk early, and make sound decisions on live sites, especially when conditions change or the pressure is on.
We are expert high voltage technicians, but if specialist input is required, we bring it in. We don’t stretch our capability or sell solutions we can’t stand behind.
Good outcomes matter to us. We don’t rush or leave loose ends. High-voltage systems demand discipline and a keen eye for detail, and that’s exactly how we work. When we finish a job, it’s because the system is doing exactly what it should.
Trained and authorised personnel. We can conduct switching preparation, isolations, equipment familiarisation to assist with site operations or site electricians gaining the experience and confidence to perform site operations.
Powerex would prepare a maintenance plan based on our assessment of the equipment and site conditions. Age, environment, importance of the equipment all contributes to determining inspection intervals.
Response times depend on site location, scope, and urgency. We prioritise critical works and work closely with project teams to meet commissioning deadlines wherever possible.
With our operations based in Brisbane, we service sites throughout Queensland, Australia, and the Pacific Islands. Wherever your high-voltage system is located, Powerex can deliver the testing and commissioning support you need. Contact our team to discuss your requirements.
