Microdischarges in cadmium vapour occur in a testing equipment for safety assessment of electric devices for explosion protection. In this work, a unified non-equilibrium model is employed to obtain the plasma properties for a current of 60 mA and gap lengths from 20 up to 160 µm corresponding to conducted experiments. The predicted voltage as a function of the discharge length agrees well with the measured values. The model provides the heat generation relevant to the ignition of a gas mixture.
