Descriere

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 m?.
  • 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 professional PC SW package HVLink which enables analysis and documenta-tion of test results.
