gis substation Monitor for testing

2021-3-13ALTANOVAs Global Monitoring for Substations provides an overall condition diagnostic system, designed to monitor the main substation assets: current transformer, voltage transformer, power transformers, circuit breakers, surge arresters and GIS switchgear.

Gas-insulated switchgear (GIS) in particular poses unique and special challenges, including the connection of the test equipment. In today‘s world, where testing is increasingly performed in a non-invasive manner, test systems must offer a certain flexibility and a wide range of testing solutions in order to get proper results in a
