  • Patent number: 11342738
    Abstract: One example includes a power generator protection system. The system includes a circuit breaker configured, when triggered, to provide an open circuit in a power line configured to conduct a current between a power grid point-of-interconnect (POI) and a power generator system. The system also includes a programmable controller configured to monitor the current and to generate a dynamic current threshold based on the current. The programmable controller can further be configured to compare the current with the dynamic current threshold and to trigger the circuit breaker based on a difference of the current relative to the dynamic current threshold to set an arc flash incident energy level of the power generator system at or below a predetermined safety level.

  • Patent number: 11128119
    Abstract: A power distribution system adapted for high current fault management during a fault event utilizes reclosing switches configured for a quick-slow-quick reclosing sequence in which the reclosing switch initially responds to the fault condition by tripping open, and then after a delay recloses for a first duration of time (slow) prior to tripping open. After another delay, the reclosing switch recloses for a second duration of time (quick) that is less than the first duration of time prior to tripping open for an indefinite interval. When installed in new segments or retrofitted in place of a fuse, reclosing switches configured with quick-slow-quick reclose timing allows for reduction of downstream customer outages, reduced I2T exposure for elements upstream of a fault event and a reduction in the duration of voltage sags experienced by customers during fault events while allowing for improved fault management configurations of the power distribution system.

  • Patent number: 10862176
    Abstract: A brief case sized battery pack for powering large power tools for use in portable applications. Large cordless power tools, such as torque guns, are often used to fasten very large nuts on wind turbines. AC power for charging may not be available depending on the location within the wind turbine. The portable rechargeable battery pack has several battery elements, each element able to power the cordless power tool. Using a selectable switch, a user manually selects the battery element to power the cordless power tool. The manually operable switch electrically connects to enable one of the first battery elements to be electrically coupled to the at least one DC output electrical connector while the DC output of a battery charger simultaneously charges all the battery elements. In one example, the DC output connector provides at least four positive DC leads all at different voltages plus ground.
