Why High Voltage Testing Matters

High voltage testing is crucial for preventing system failures and electrical hazards. It helps identify and resolve issues before they escalate, reduces maintenance costs, and extends the lifespan of electrical assets. Testing also ensures compliance with safety regulations, protecting both your infrastructure and personnel.

High Voltage Power System Testing

Our team delivers specialised testing and commissioning services for industrial, commercial, and utility sectors in Melbourne:

High Voltage Cable Testing

We use Very Low Frequency (VLF) testing, partial discharge (PD) diagnostics, and Tan Delta testing to evaluate cable insulation health, detect faults early, and prevent unexpected failures.

High Voltage Equipment Testing

We provide on-site and mobile testing for insulated gloves, PPE, and electrical safety equipment to ensure compliance with Australian safety standards.

Transformer Testing

Our transformer testing services include oil analysis (DGA), winding resistance measurement, and power factor testing. These tests maintain reliability and prolong transformer lifespan.

Switchgear and Substation Testing

We conduct functional, performance, and compliance tests on circuit breakers, relays, switchgear, and complete substation systems to ensure safe and reliable operation.

Protection Relay Testing

Our services cover programming, calibration, and functional testing of protection relays, ensuring the integrity and safety of your electrical networks.

Other Electrical Testing Services

We also provide essential electrical safety services for Melbourne businesses, construction sites, and rental properties:

Electrical Safety Checks

Mandatory safety checks for rental properties, including appliances, fixed installations, and fittings.

Switchboard Testing

Inspection and testing of RCDs, circuit breakers, and switchboards for ongoing compliance.

Test and Tag

Routine testing and tagging of electrical equipment to identify faults early and prevent hazards.

High Voltage Commissioning

High Voltage Commissioning ensures your high voltage systems are installed and operating as designed. This involves key tests like insulation resistance checks and high voltage withstand tests to confirm safety and performance.

By resolving problems before systems go live, commissioning boosts reliability, reduces downtime, and ensures compliance with strict standards.

Our Melbourne commissioning services include:

System verification and validation
Functional performance assessments
Testing of protective relays
Calibration of instruments and meters

Frequently Asked Questions: HV Commissioning and Testing

What is the difference between commissioning and testing?

High voltage testing focuses specifically on verifying the insulation integrity and performance of individual electrical components by applying controlled high voltage stresses to detect defects and ensure safety before use. In contrast, high voltage commissioning is a broader process that includes testing but also involves inspecting, integrating, and validating the entire electrical system or installation to confirm that all parts function together correctly and safely under real operating conditions, ultimately ensuring the system is ready for reliable service.

What is considered high voltage testing?

High voltage testing is a process used to evaluate the insulation strength and overall durability of electrical equipment and components by applying voltages significantly higher than their normal operating levels. This testing ensures that devices such as transformers, cables, switchgear, and insulators can withstand electrical stresses without breakdown, failure, or safety hazards. By subjecting equipment to controlled high voltage conditions, engineers can detect weaknesses in insulation, verify compliance with safety standards, and prevent potential faults like short circuits or arcing during actual operation. High voltage testing is essential for confirming the reliability and safety of electrical systems in power generation, transmission, and distribution.

When should high voltage testing be performed?

High voltage testing is done during installation, after any repair, or before new systems go live. It’s also part of routine maintenance to spot insulation wear early and prevent costly outages.

What industries require high voltage testing and commissioning?

Industries such as power generation, transmission and distribution utilities, manufacturing plants, data centers, renewable energy (solar and wind), and heavy industrial facilities commonly require high voltage testing and commissioning services.

How often should high voltage equipment be tested?

Testing is advised every one to three years. The exact timing depends on conditions, environment, and manufacturer advice. Regular checks help find insulation aging and avoid sudden failures.

What are common issues found during high voltage testing?

Common problems include insulation damage, moisture entry, partial discharge, and weak terminations. Heat or stress can also cause wear. Early detection keeps equipment safe and power steady.

What are the costs involved in high voltage testing and commissioning?

Costs vary by voltage level, number of units, test type, and site setup. You can request a custom quote tailored to your project’s needs and schedule with us.
