What We Do
Our Services
ESB Power delivers specialist high-voltage maintenance, testing, and commissioning services to Australia's leading mining, utilities, renewable energy, and industrial operators.
Proactive maintenance for critical HV assets
HV Maintenance
ESB Power delivers comprehensive high-voltage maintenance services for substations, switchgear, transformers, cables, and associated HV infrastructure. Our experienced teams work across mining, utilities, renewable energy, and industrial sectors throughout Australia.
We understand the critical importance of asset reliability and operational continuity. Our maintenance programs are designed to reduce unplanned outages, extend asset life, and ensure compliance with Australian standards and safety regulations.
Precision testing across all HV asset classes
HV Testing
ESB Power provides specialist high-voltage testing services to assess the condition, performance, and compliance of electrical assets. Our testing capabilities cover a broad range of HV equipment and infrastructure across all industry sectors.
Using advanced diagnostic equipment and proven methodologies, our teams deliver accurate, reliable test results that inform maintenance decisions, support commissioning activities, and ensure assets meet required performance and safety standards.
Safe, compliant energisation of new and upgraded assets
Inspection & Commissioning
ESB Power delivers thorough inspection and commissioning services for new HV installations, upgrades, and asset replacements. We ensure all equipment is correctly installed, tested, and verified before energisation — supporting safe, compliant, and reliable operation.
Our commissioning teams work closely with project managers, contractors, and asset owners to coordinate activities, manage documentation, and meet project timelines. We bring deep technical expertise and a strong focus on safety to every commissioning engagement.
Detect faults before they become failures
Thermographic Surveys
ESB Power provides professional thermographic (infrared) survey services for high-voltage and low-voltage electrical assets. Thermal imaging is one of the most effective predictive maintenance tools available — identifying hotspots, loose connections, overloaded circuits, and failing components before they cause unplanned outages or equipment damage.
Our thermographic surveys are conducted by qualified thermographers using calibrated infrared cameras. We deliver detailed reports with thermal images, findings, risk classifications, and recommended remediation actions — giving asset owners the information they need to prioritise maintenance and manage risk.
Ensuring your protection systems perform when it matters most
Protection Relay Testing
ESB Power delivers specialist protection relay testing and calibration services for all major relay types and manufacturers. Correctly functioning protection systems are critical to the safety of personnel, the integrity of electrical assets, and the continuity of operations.
Our engineers are experienced across a wide range of protection schemes including overcurrent, earth fault, differential, distance, and busbar protection. We use modern relay test equipment to verify relay settings, operating times, and coordination — ensuring your protection systems operate correctly under fault conditions.
Comprehensive assessment of transformer condition and performance
Transformer Testing
ESB Power provides a full suite of transformer testing services to assess the condition, performance, and integrity of power and distribution transformers. Regular testing is essential to identify developing faults, assess insulation condition, and make informed decisions about maintenance, refurbishment, or replacement.
Our teams are equipped with specialist transformer test equipment and have extensive experience testing transformers across all voltage classes and ratings. We work with asset owners to develop testing programs that align with maintenance schedules, operational requirements, and budget constraints.
