At Dilro Services, we provide professional three-phase appliance Testing to ensure your heavy-duty electrical equipment is safe, compliant, and performing reliably. Our testing procedures meet all AS/NZS 3760:2022 requirements and WorkSafe regulations, helping your business minimise risk and maintain operational integrity.

Three-phase appliances are regularly used in industrial, commercial, and construction environments to power high-demand machinery and equipment. Due to their increased electrical load, they pose greater safety risks if not regularly inspected and tested.


Why Three-Phase Testing Matters


Faults in three-phase equipment can have serious consequences, from equipment failure and power outages to life-threatening electrical incidents. Regular testing helps detect issues before they escalate and ensures your workplace stays compliant with safety regulations. What is at stake:

  • 🟑 Electric Shock Risk:

    Faulty three-phase equipment can expose users to dangerous voltages.

  • 🟑 Equipment Damage:

    Undetected faults can cause appliance failure, leading to costly repairs or replacements.

  • 🟑 Fire Hazards:

    Electrical faults in high-power systems can result in overheating and potential fires.

  • 🟑 WHS Non-Compliance:

    Failure to test high-powered equipment can lead to legal liabilities, penalties, and safety breaches.


Our Comprehensive Services


  • 🟑 Visual Safety Inspections:

    We thoroughly inspect three-phase equipment for physical wear, damage, and secure connections.

  • 🟑 Portable Appliance Testing (PAT):

    We conduct in-depth testing using calibrated equipment to verify continuity, polarity, insulation resistance, and leakage current, tailored to the requirements of three-phase systems.

  • 🟑 Load & Operational Function Testing:

    We verify appliances under simulated working conditions, ensuring safe and reliable performance.

  • 🟑 Digital Compliance Reports & Asset Management:

    We provide detailed audit-ready reports and compliance logs for full transparency.

  • 🟑 Identification & Labelling:

    Each appliance is tagged with a durable, tamper-proof label indicating test status, test and retest dates, technician ID, and a colour-coded status for easy compliance tracking.

  • 🟑 Scheduled Testing and Reminders:

    We track your testing schedule and provide timely reminders, helping you stay compliant without the hassle.


Testing Intervals in Australia


Testing frequencies for three-phase appliances vary based on workplace environment, risk level, and equipment type (portable or fixed), as mandated by AS/NZS 3760:2022 and state WorkSafe regulations. High-risk environments, such as construction sites, require portable appliances to be tested every 3 months, while manufacturing facilities typically need testing every 6 months for portable equipment and 6–12 months for fixed equipment. Low-risk settings, like offices, require testing every 12 months for portable appliances or up to 24 months for fixed, low-use equipment, subject to a risk assessment. For specific requirements, consult WorkSafe Queensland, other state WorkSafe bodies, or AS/NZS 3760:2022 at Standards Australia.
