Abstract: Partial discharges in a high voltage electric machine can be monitored by a partial discharge monitor connected to the high voltage electric machine successively via a capacitive coupler and a connection cable. The connection cable can have a conductive element designed to self-destruct in the presence of electric current amplitude significantly exceeding expected current amplitudes from said partial discharges, and having diameter designed to avoid creation of additional partial discharges within the cable itself. The connection cable can be light enough to avoid adding excessive weight to the stator windings.

Abstract: The capacitive sensor can have a sensing body having two flat conductor elements positioned parallel to one another and held spaced apart from one another, and having a thickness normal to the flat conductor elements, the sensing body having at least one aperture formed across its thickness. The capacitive sensor can be used to measure an air gap between a stator and rotor of a rotary electric machine, and the presence of the apertures can facilitate ventilation and/or improve linearization process of capacitive sensor through redistribution of its current vs distance signal along the measuring range, thus potentially increasing signal to noise ratio where it is the challenging to do so.
