Omicron HGT1
The Omicron HGT1 is a reliable instrument designed to accurately measure phase and touch voltages in a substation grounding system. When used with compatible test injection systems (such as the Omicron CPC 100 and CP CU1), it uses a variable-frequency test current to simulate ground faults, allowing phase-touch voltages to be measured and calculated and noise of the HGT1 Digital filtering are added to increase measurement accuracy and provide better suppression. It also has a logging function that allows you to store multiple measurements, which can later be downloaded for reporting and analysis.
Special Features:
- Portability: This battery-operated handheld device facilitates measurements at various locations inside and outside the substation.
- Simulated resistance: The device accurately simulates body and shoe resistance according to relevant standards.
- Frequency-selective calibration: This enables frequency-selective calibration.
- Advanced noise suppression: Digital filtering increases noise suppression, resulting in more accurate measurements.
Applications:
- Measurement of phase-touch voltage at several points.
- Evaluation of substation ground planning systems.
- Step and touch voltage measurements.
- Measurement of uplift potential.
