    摘要: A measurement module receives crosstalk compensation factors that include distance factors based on respective distances of a current sensor of the module from respective current sensors of other measurement modules and phase difference factors based on respective differences between the phase of a source current measured by the module and respective phases of source currents measured by the other modules. The module monitors messages reporting current measurements transmitted from the other modules connected to a broadcast bus, of current measurements made by respective current sensors of the other modules measuring other respective source currents. The module determines a reported current that is computed as a function of current measurement by the module's current sensor, reported current measurements monitored from the other modules, and the received crosstalk compensation factors. The module transmits the determined reported current over the broadcast bus to the other modules and a central controller.

    摘要: An operating mechanism is provided for an electrical enclosure. The operating mechanism includes a switch operator, and a housing to house the switch operator. The switch operator includes a portion which extends through one of one or more holes in the electrical enclosure, and can be manipulated by an external handle to operate an electrical switching device, such as a circuit breaker, that is housed in the electrical enclosure. The housing includes a cavity to house and protect an external antenna or other electrical device, which is connectable to an electrical cable that extends from the cavity into an interior of the electrical enclosure via the hole(s). The electrical cable can be connected to a monitoring system inside of the electrical enclosure. The housing is mountable onto an exterior surface of a wall of the electrical enclosure to cover the hole(s).
