“The HGT1, in combination with the CPC 100 and CP CU1, allows quick and convenient step and touch voltage measurements in and around a high-voltage substation.”

Benefits of this solution

Personnel safety

Step and touch voltage tests are a very important factor when it comes to ensuring human safety within the substation and surrounding areas, especially during an electrical fault.

Smart and powerful

With the CPC 100 + CP CU1 you can generate the test current at non-network frequency to avoid measurement errors and inject it into a power line for measuring true step and touch voltage values.

Noise suppression

By using the frequency selective HGT1 voltmeter, the step and touch voltages can be measured at the same frequencies as the injected test current. This allows effective noise suppression for a highly accurate measurement.

Mobile solution

Since the HGT1 is a handheld device, you can easily and quickly access different measurement locations, eliminating the need for a separate set of long measurement cables.
