MI 3295 Step Contact Voltage Measuring System is a voltage measuring system for testing and verification of protective earthing of power stations, substations and other power systems.

MEASURING FUNCTIONS

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

KEY FEATURES

• 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.

A PAT is essentially a number of testing instruments built into one case designed specifically for one main purpose; the easy, quick, and accurate testing of appliances/electrical equipment. Portable Appliance Testers do not have multiple test leads to be inserted or attached unlike other types of test equipment.
