Abstract: A combustor for a gas turbine system includes a combustor casing having an interior-establishing wall, and a chamber extending to the interior-establishing wall. In addition, the combustor includes an igniter assembly disposed within the chamber such that a tip of the igniter assembly is positioned radially outwardly from the interior-establishing wall. The igniter assembly includes a first electrode, a second electrode, and an insulator. In addition, the first electrode, the second electrode, and the insulator form a cavity, the second electrode forms an outlet passage extending from the cavity, a maximum cross-sectional area of the cavity is greater than a minimum cross-sectional area of the outlet passage, and the first electrode and the second electrode are configured to ionize gas within the cavity in response to an electrical current applied to the first electrode or to the second electrode.

Abstract: Embodiments of the present disclosure relate to a spark gap device that includes a first electrode having a first surface and a second electrode having a second surface offset from and facing the first surface. The spark gap device also includes a light source configured to emit light toward at least the first surface such that photons emitted by the light source when the spark gap is operated are incident on the first surface and cause electron emission from the first surface. The light source includes a discharge probe having a third electrode sealed in a tube filled with an inert gas. The spark gap device may not include a radioactive component.

Abstract: The present disclosure relates to gas turbine engine operation in which an igniter assembly is provided with an electrical energy input (e.g., an electrical waveform) that is configured to increase a likelihood of igniting a fuel-air mixture surrounding the igniter assembly. In certain embodiments, the igniter assembly is supplied with an augmented electrical waveform that may reduce a quantity of sparks generated by the igniter assembly before successful light-off (e.g., ignition) of the fuel-air mixture is achieved (e.g., as compared to a quantity of sparks generated to achieve ignition by an igniter assembly that receives an electrical energy input in the form of a conventional electrical waveform). Accordingly, the augmented electrical waveform may reduce wear (e.g., via oxidation) on electrodes of the igniter assembly, such as a primary electrode (e.g., a center electrode) and a secondary electrode (e.g., an outer shell electrode) disposed about the primary electrode.

Abstract: An electric component for an electric machine includes a body having slots defined therein, and a conductive winding extending out of axial end(s) of the slot(s). The electric component may include any electric machine component having conductive windings, e.g., a stator for a generator. The electric component includes a resin dam around the conductive winding at axial end(s) of the slot(s). The resin dam blocks liquid communication through at least a space between the conductive winding and an inner surface of the slot(s), during manufacture. The electric component also includes a (solidified) insulating resin in the slot(s) and against the resin dam(s) at the axial end(s) of the slot(s). Any number of the conductive windings and slots may include a resin dam, e.g., one, some or all. The resin dams ensure complete filling of the slots and encapsulation of the conductive windings.

Abstract: Partial discharge detection techniques are provided. In one aspect, a method of detecting partial discharge in an electrical power system having a power electronics converter is provided. A first current signal is captured in response to a first applied voltage. A second current signal is captured in response to a second applied voltage, the second applied voltage being different than the first applied voltage. The first current signal is set as a reference signal. A difference signal is determined based on the second current signal and the reference signal. A determination is made as to whether partial discharge is present based on the difference signal. The method may iterate, and for each iteration, the reference signal is refreshed on a rolling basis as a previously captured current signal measured in response to a previously applied voltage. The applied voltage is also stepped up or down for each iteration.
