Metrel MI 3295 Step Contact Voltage System

Metrel MI 3295 Step Contact Voltage System

Due to high test current (up to 55 A) and effective noise cancellation the MI 3295 ensures very accurate and stable measurements of Step and Contact Voltages with the resolution down to 10 µV. Few voltmeters can be used simultaneously for faster analysis of voltage distribution around the tested object.

All test results and parameters can be saved into the instrument’s memory for further downloading, analysis and test report printing with the help of the PC SW Metrel ES Manager or HVLink PRO.

Metrel MI 3295 Functions

• Measurement of step voltage and contact voltage – Also known as “step and touch voltage tests” ideal for high voltage transmission systems, fences around substations and other critical locations to ensure the safety of people and animals surrounding the area.
• Measurement of earthing resistance with a resolution of 1 mΩ
• Measurement of specific earth resistance

Key Features

• Highly accurate results thanks to effective suppression of noise and immunity against changing earth currents
• High safety due to a low output voltage (55 V)
• Autonomous Step Voltage meter means no need for long voltage leads
• Low weight
