At Proximanz, we know how important it is to keep your three-phase electrical systems safe, reliable, and fully compliant. Whether you run industrial machinery, commercial equipment, or other complex electrical setups, our expert testing services ensure everything operates efficiently while protecting your people and property.
What Is Three-Phase Testing?
Three-phase testing is a thorough inspection and assessment of all conductors in a three-phase electrical system. These systems use three live (active) phases, along with a neutral and an earth connection, and typically operate at 400–415 V. Because of the higher voltages involved, they require more detailed and specialised testing compared to single-phase systems.
Our testing process includes:
Visual Inspection – Checking plugs, cables, and connectors for damage or wear.
Earth Bond Test – Verifying a strong grounding connection to prevent electric shocks.
Insulation Resistance Test – Measuring insulation quality to ensure it prevents current leakage.
Leakage Current Test – Ensuring any leakage is within safe limits, especially for equipment with electronic controls.
Why Three-Phase Testing Matters
Safety Protection
Faults such as damaged insulation or poor grounding can cause electric shocks, fires, or major equipment failures. Testing identifies issues before they become dangerous.
Compliance with Standards
Three-phase testing helps your business meet New Zealand safety regulations. Staying compliant avoids penalties and keeps your workplace legally protected.
Reduced Downtime
Regular checks detect problems early, preventing unexpected breakdowns that disrupt production and cause costly delays.
