For safe, trouble-free grid operation, Axpo offers comprehensive services in all aspects of earthing systems for high-voltage installations, as well as troubleshooting solutions. We help you avoid safety deficiencies in electrical systems. These can cause serious damage to the plant and its surroundings, and pose a danger to plant personnel and third parties. 

For safe, trouble-free grid operation

  • Axpo has modern equipment at its disposal
  • Measuring instruments adapted to the application guarantee conclusive results
  • Mobile devices enable flexible application

Measurement of earthing systems

In the event of a malfunction, high voltages can occur even on earthed elements in the area of high-voltage systems. A professional earthing measurement confirms the legally prescribed personnel safety of the systems. In the event of problems, measures to improve safety are proposed. Axpo also checks the quality of earthing conductor connections with precise resistance measurements. This ensures that residual currents are safely diverted.

Measurement of line impedances

Faults on a medium, high or extra-high voltage line can be detected with correctly set protective devices and the corresponding plant components can be selectively switched off. This reduces failures to a minimum. In order to minimise the risk of incorrect switching off or not switching off, precise line impedance values are essential. A measurement can be used to determine the values for good parameterisation of the protective devices.

Your advantages: Benefit from our know-how

  1. A professionally performed earthing measurement increases the safety of the systems even in the event of a malfunction. 
  2. Precise knowledge of the line impedance allows precise adjustment of the protective devices.
  3. The measured values are assessed in accordance with the statutory safety regulations and appropriate measures are proposed.
