The OMICRON HGT1 is a specialized instrument used for measuring step and touch voltages, as well as ground impedance in substations and power systems. It works in combination with CPC 100 and CP CU1 to inject controlled test currents and simulate fault conditions, enabling accurate assessment of grounding system safety. This ensures compliance with standards such as IEEE 81 and EN 50522 while verifying safe operating conditions for personnel.
Technical Highlights: Measures step & touch voltage and ground impedance | Works with variable frequency injection (15–400 Hz via CPC systems) | High-sensitivity voltage detection with FFT-based measurement | Supports fall-of-potential method for grounding analysis | Compatible with PTM (Primary Test Manager) software for automated testing | Designed as an add-on unit for CPC 100 / CP CU1 systems.
Ideal for grounding system verification, substation safety studies, and compliance testing.
