Omicron HGT1 from Brandis Hire

Description

The Omicron HGT1 is used to safely and accurately measure step and touch voltages in a substation
earthing system.

When used with a suitable 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. 

Applications:

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