At Powerex Services, our testing and commissioning process is about absolute certainty. We leave no stone unturned to verify that your high-voltage installation is fit for purpose, tested to design, and genuinely ready to be switched on. We make sure your high-voltage installation is safe, compliant, and ready to be energised.
Protection relays are your last line of defence, and there’s no room for error. We test relay settings, logic, timing, and coordination to ensure faults are detected and cleared exactly as intended, protecting people, equipment, and the wider network.
We put your switchgear through its paces before it ever sees load. From mechanical operation to insulation integrity, we confirm breakers, isolators, and protection devices operate safely and reliably under real-world conditions.
Accurate data matters. We test CTs and VTs for ratio, polarity, accuracy, and insulation performance so your protection and metering systems are working with information you can trust.
Transformers are critical assets, and costly to get wrong. Our extensive testing verifies winding condition, insulation health, and overall performance prior to energisation or return to service, reducing risk from day one.
Testing individual components isn’t enough. We commission systems as a whole, confirming protection coordination, interlocking, communications, and integration with SCADA and control systems.
We carry out statutory and compliance testing to meet regulatory, asset owner, and network requirements, backed by clear reporting that supports approvals, audits, and final handover.
If a site isn’t commissioned properly, it won’t operate properly, or at all. Missed tests, incorrect settings, or poor system integration can delay energisation, cause unplanned downtime, and expose people and equipment to serious risk.
The consequences are real: damaged assets, electrical incidents, failed inspections, and costly rework. Thorough testing and commissioning avoid these issues and ensures your system performs safely from the moment it’s switched on.
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.
Not only can equipment change during transport, but on-site standards of testing may differ from factory and verification in the final resting position is paramount. Design is complete and integrated.
Commissioning times are heavily dependent on design and construction completion and quality. The testing procedure runs smoothly with the absence of defects and design flaws.
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.
If your project is approaching energisation or you need assurance that an existing system is performing as designed, Powerex Services delivers testing and commissioning that removes doubt and reduces risk.
