  • Patent number: 12038467
    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.

  • Patent number: 11982648
    Abstract: An environmental condition may be measured with a sensor (10) including a wire (20) having an ultrasonic signal transmission characteristic that varies in response to the environmental condition by sensing ultrasonic energy propagated through the wire using multiple types of propagation, and separating an effect of temperature on the wire from an effect of strain on the wire using the sensed ultrasonic energy propagated through the wire using the multiple types of propagation. A positive feedback loop may be used to excite the wire such that strain in the wire is based upon a sensed resonant frequency, while a square wave with a controlled duty cycle may be used to excite the wire at multiple excitation frequencies. A phase matched cone (200, 210) may be used to couple ultrasonic energy between a waveguide wire (202, 212) and a transducer (204, 214).
