At MPT Services, we understand that relay testing isn't just a technical task—it's a responsibility that directly impacts the reliability and safety of your operations. In this blog, we outline what you should look for when selecting a service provider for protection relay testing and commissioning, along with why it matters for your project.
Why Protection Relay Testing Matters
Before diving into provider criteria, it’s important to understand the role of protection relay testing. Protection relays must operate accurately and quickly in the event of electrical faults such as short circuits, overloads, or ground faults. A relay that trips too late—or fails to trip at all—can lead to:
- Equipment damage
- Fire hazards
- Costly downtime
- Safety violations
Through relay testing and commissioning, these devices are calibrated, validated, and tested under simulated fault conditions to ensure they respond correctly in real-world scenarios.
Key Qualities to Look for in a Relay Testing Provider
Here are the top factors to consider when choosing a relay testing and commissioning company in Australia:
- Technical Expertise and Certification
The complexity of protection systems requires expert-level understanding of electrical engineering, fault analysis, and relay logic. Your provider should:
- Employ certified engineers and technicians
- Be familiar with major relay brands (e.g., ABB, Siemens, Schneider, GE, SEL)
- Have experience across various sectors such as utilities, renewables, data centres, and heavy industry
At MPT Services, our team includes highly trained professionals with real-world experience in testing and commissioning of protection relays across diverse environments.
2. Use of Modern Testing Equipment
Relay testing requires advanced diagnostic tools that can simulate fault conditions and record relay responses with precision. Always ensure your provider uses:
- Portable and computer-based relay test sets
- Accurate current and voltage injection systems
- Reporting software to document results
Updated tools mean faster, more accurate testing and smoother commissioning processes.
3. Compliance with Australian Standards
In Australia, protection systems must comply with standards such as AS/NZS 2081, AS/NZS 3000, and network operator guidelines. A competent provider will:
- Follow national and utility-specific regulations
- Deliver fully documented test reports
- Assist with audits, inspections, and compliance submissions
MPT Services strictly adheres to regulatory standards in all our HV testing and commissioning services in Australia, including relay protection work.
4. Track Record and References
Don’t hesitate to ask for past project examples or client references. Look for:
- Projects similar in size and complexity to yours
- Experience in your specific industry (e.g., mining, renewables, power generation)
- On-time project delivery with minimal rework
A trusted provider will be transparent about their project history and results.
5. Full-Service Commissioning Support
Some companies only offer testing services without end-to-end commissioning support. Ideally, your provider should offer:
- Installation verification
- Functional and performance testing
- Relay configuration and settings validation
- On-site troubleshooting and system optimisation
MPT Services offers comprehensive protection relay testing and commissioning across Australia, ensuring your system is not only tested but ready for full operation.
6. Safety and Risk Management Culture
Working with high-voltage equipment poses serious safety risks. A reliable service provider must:
- Follow stringent safety protocols
- Carry necessary insurance
- Have a documented risk management strategy
At MPT Services, safety is non-negotiable. Our team works under strict OH&S guidelines, ensuring minimal risk and maximum reliability.
Why the Right Choice Matters
Choosing the right relay testing and commissioning provider isn’t just about checking a box. It’s about:
- Ensuring operational continuity
- Avoiding unplanned shutdowns
- Reducing risk to people and equipment
- Meeting regulatory compliance
- Building long-term infrastructure reliability
With today’s increasing power demands and tighter safety regulations, businesses can’t afford to cut corners when it comes to protection systems.
