  • Service High Voltage Products gas monitoring systems

    An indoor GIS inevitably needs to connect to an outdoor air-insulated substation (AIS). Some GIS compartments feed through the building walls and are therefore partially indoors/outdoors, resulting in an axial temperature gradient, i.e. along the axis of the compartment. Axial temperature gradients cause density gradients and distort the readings
