Abstract
A voltage and/or current sensing device for low-, medium- or high voltage switching devices is disclosed as a constructively enhanced measuring device with high performance for use in switching devices. The sensing device can include a first voltage sensing part, a second voltage sensing part and a current sensing part all arranged in a same common single housing separated, from the switching device, in a way that an output wire from the first voltage sensing part, for sensing voltage at an upper terminal of the switching device, is located close to the current sensing part, the output wire being applied with an insulating cover, and mechanically fixed to the current sensor part, and/or the output wire being implemented in an isolation body, and only located near to the current sensing part.
