  • Publication number: 20190146022
    Abstract: A test circuit performs fault detection tests on a motor branch circuit, to detect pre-existing faults before a motor start-up to pre-empt potential damage to the motor branch circuit therefrom. The test circuit is configured to be coupled to the phase lines of a motor branch circuit at a set of test points strategically located on the phase lines. The test circuit includes test lines that are each coupled to a different one of the phase lines at one of the set of test points. The test circuit includes a test controller that, during a test mode, sequentially presents a low voltage supply to each phase line through the test line coupled thereto, to test for ground faults then sequentially couples the low voltage supply across each possible pairing of the phase lines to test for line-to-line faults. The test mode can be initiated manually or automatically.

  • Publication number: 20180287370
    Abstract: An electronic overload relay leverages a ratio metric current design to permit size and cost optimized circuit components that can be used to sense current for purposes of protecting motors by detecting overcurrent conditions in branch motor applications in lieu of thermal overload devices. A current divider is used to significantly reduce the current that must be sensed by a magnetically coupled toroid to permit its components to be size and cost optimized and to be implemented easily on a printed circuit board. The DC resistance can be used to provide a coarse design that can be calibrated pre-manufacture to establish the accuracy required in sensing motor load current by adjusting the value of the burden resistor. Precision printed circuit board traces can be used to ensure repeatability during manufacturing. A sweepable trigger value generator can permit operation over the entire range of FLC and the threshold can be calibrated into the device.
