METREL - Model MI 3295 -Step Contact Voltage Measuring System
The MI 3295 Step Contact Voltage Measuring System is a voltage measuring system intended for testing and verification of protective earthing of power stations, substation and other power systems. The system consists of Station for current generation and autonomous voltage Meter. 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. A 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.
- Measurement of step voltage and contact voltage.
- Measurement of earthing resistance with resolution of 1 mΩ.
- Measurement of specific earth resistance.
- High accuracy of the measurements due to a high current of up to 50 A and effective suppression of noise.
- Excellent immunity even against changing earth currents.
- Autonomous Step Voltage meter: no need for long voltage leads.
- Low weight.
- High safety due to low output voltage (55 V).
- Downloads test results directly to the PC with the help of the profes-sional PC SW package HVLink which enables analysis and documenta-tion of test results.
