HGT1 User Manual 

The Omicron HGT1 is used to safely and accurately measure step and touch voltages in a substation earthing system.
When used with a suitabe test injection system (for example by using the Omicron CPC 100 and CP CU1) a variable frequency test current is used to simulate a ground fault and the step and touch voltages present can be measured and calculated.
The HGT1 uses digital filtering to ensure effective noise suppression and provide more accurate measurements.
A logging function allows many measurements to be taken and stored internally, for later download to a computer for reporting and analysis.

Key features
  • Mobile, battery operated handheld device – simplifies measurements at various locations inside and outside the substation
  • Simulates body and shoe resistance (as defined in relevant standards)
  • Frequency-selective measurements
  • Digital filtering makes noise suppression more effective and measurements more accurate.


  • Measuring step and touch voltages at multiple locations
  • Substation Earthing System Testing
  • Step and Touch Voltage Measurement
  • Earth Potential Rise Measurement
