Step Contact Voltage Measurement System- Model MI-3295


MI 3295 Step Contact Voltage Measuring System is designed for testing and verification of protective earthing of power stations, substation and other power systems.

Measuring Functions:

  • Measurement of step voltage and contact voltage
  • Measurement of earthing resistance with resolution of 1 mOhm
  • Measurement of specific earth resistance

Main features:

  • Graphic LCD displays on Meter and Station.
  • Autonomous Step / Contact Voltage Meter(s).
  • 1500 memory locations in data flash memory for storing test results & parameters.
  • USB and RS232 ports on Meter for communication with PC.
  • Synchronization between Meter and Station.
  • Large test current of up to 50 A.
  • Stable and accurate results due to a DSP measuring system.
  • Fully compatible with new METREL HVLink PRO PC software package.
Step voltage Measurement:
MI3295
The measurement is performed between two ground points at a distance of 1 m as shown The 25 kg measuring probes simulates the feet. The voltage between the probes is measured by a voltmeter with an internal resistance of 1 kOhm. that simulates the body resistance.
Contact Voltage Measurement

Standard Set

The measurement is performed between an earthed accessible metal part and ground as shown. The voltage between the probes is measured by a voltmeter with an internal resistance of 1kOhm. that simulates the body resistance.
