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 apparatus can be used for detecting a liquid contaminant in a rotating cavity of an electric machine. The apparatus can have a magnetic field source mounted to a non-rotary base and transmitting a magnetic field across a gap between the base a housing of the cavity, an interrogation circuit having a coil magnetically coupled to the magnetic field source across the gap via the magnetic field, and a distal circuit portion having electrical contacts separated by a spacing fluidly communicating with the cavity; and a detection circuit mounted to the base and having a coil magnetically coupled to the magnetic field and a detector detecting a variation occurring in the detection circuit upon change of a permittivity of the liquid across the spacing, the variation being indicative of the liquid contaminant.

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.
