The Swiss TSO, Swissgrid, is carrying out installation work on the 220kV high-voltage lines in Handeck – Innertkirchen in March 2021. The Norwegian company Heimdall Power is providing sophisticated sensor units (neurons) which are installed on the conductors using a helicopter. The neurons measure a wide range of relevant values for the conductors without using an external power supply. The measured values ​​obtained are sent via the cellular network to a cloud-based monitoring application for further processing. To read more about the sensors, software and use cases visit heimdallpower.com.

This is a setup for the monitoring of lines with the aim of better recording and more precisely modeling their thermodynamic behavior. Swissgrid is interested in a reliable prognosis of the line capacity taking into account the conductor cable properties and the climatic conditions. The aim is to check whether the static current values ​​used today for operational management could be replaced by forecast values ​​that consider the actual microclimatic conditions. The real-time monitoring starts in April 2021 and will continue for 2 years, with an option of 2 additional years.
