New Possibilities for Step and Touch Voltage Testing

It is important to test step and touch voltages within your facilities and the surrounding areas.

When running high-voltage facilities, it is essential that suitable measures are employed to ensure the safety of people and animals. That is why it is important to test step and touch voltages within your facilities and the surrounding areas.

OMICRON's CPC 100 and CP CU1 measure line and ground impedances as well as step and touch voltages thanks to the battery-operated handheld HGT1 device.

The CPC 100 and CP CU1 measuring systems can read variable frequency test currents. Mains-related interference can, therefore, be suppressed, resulting in accurate, repeatable measurements. Weighing in at 64 lbs (29 kg) and 62.8 lbs (28.5 kg), the CPC 100 and the CP CU1 measuring systems can easily be transported from one location to the next. By contrast, conventional methods require complicated procedures and very heavy equipment.

The HGT1 voltmeter, which measures selective frequencies, reads the test current from the CPC 100. This allows the step and touch voltages to be measured easily and quickly and simulates the body's electrical resistance, as per the required standards. "With the HGT1, step and touch voltage testing can be carried out quickly, easily and accurately," explains Moritz Pikisch, Product Manager at OMICRON. "You can carry out measurements at different locations as the HGT1 doesn't require long measuring cables."
