Short description

The standard deals with humidity measurement in carbon dioxide (CO2), which is to be used as an alternative insulating gas to SF6 in medium and high-voltage systems. The focus is on the selection of suitable measurement methods that provide reliable results despite high cross-sensitivity to CO2.A central concern is the definition of specific parameters and measurement parameters for moisture determination in CO2. The standard describes various measurement principles and evaluates their suitability in the context of CO2, including aspects such as measuring range, accuracy, stability and calibration capability of the sensors.
