Metrel MI3295 Step Contact Voltage Measuring System (with plates)
What is the Metrel MI 3295 Step & Contact Voltage Measuring System?
The Metrel MI 3295 is a specialist high-voltage earthing test system designed for UK electrical engineers and power network technicians working on substations, power stations, distribution networks and HV installations. It is purpose-built for step voltage, contact voltage and protective earthing verification, helping engineers assess site safety during commissioning, maintenance and fault investigations.
Using a high test current of up to 55 A with advanced noise suppression, the MI 3295 delivers stable and highly accurate measurements, even in electrically noisy environments. The system consists of a current-generating station and an autonomous voltage meter, allowing safe, repeatable testing without long potential leads and enabling faster assessment across large sites.
Why is step and contact voltage testing critical on HV sites?
Step and contact voltage testing is essential for confirming that earthing systems will protect personnel during fault conditions. The MI 3295 allows engineers to accurately map voltage gradients around HV assets, identify unsafe areas and verify compliance with industry standards before systems are energised or returned to service.
