  • Power transformer inrush current detector
    Patent number: 9891289
    Abstract: Techniques for detecting an inrush current in a power transformer in are disclosed. For example, the presence of an inrush current on a current path in a power transformer may be determined by receiving a signal from a Rogowski coil positioned on a current path of a power transformer, the signal corresponding to a current flowing in the current path; sampling the received signal to produce samples of the received signal; and analyzing the samples of the received signal relative to at least two criteria to determine whether an inrush current is present. When an inrush current is present, operation of a protective relay is blocked.

  • Thermally dissipated lighting system
    Patent number: 9890943
    Abstract: A lighting system or luminaire can comprise two environmentally sealed housings. One of the housings can house one or more light emitting diodes. The other housing can house a driver for supplying electricity to the light emitting diode or diodes. The housings can be nested together. For example, one of the housings can extend partially into a cavity of the other housing. A portion of the cavity can remain unfilled when the housings are nested, to provide an air gap between the two housings. The air gap can be environmentally exposed, for example exposed to moisture when the lighting system is mounted outdoors.
