Monitoring of asymmetric short circuit currents

As an early adopter of digital solutions, the Swiss TSO Swissgrid recently opted for CONDIS metering products to complete a monitoring system within their 380/220kV GIS substation at Châtelard/Valais, where one of Europe’s largest hydro power plant is connected to the transmission grid.

The main purpose of this system is to measure with high precision the network faults coming from generators in the hydro plant. The collected records are used to compare network failure simulations with real measurement and potentially as proof of failure towards third parties.
