    Abstract: A fault detection system that includes a recloser configured to perform a reclosing operation in response to detecting overcurrent. The system also includes a sensor adapted to be mounted to a can of a transformer and extending into the can for measuring pressure therein, where the sensor includes a mechanical indicator that extends when overpressure is detected. The transformer further includes a radio mounted to the can and coupled to the sensor, where the radio includes a switch coupled to the mechanical indicator and a transmitter. When the mechanical indicator extends in response to detecting overpressure in the can it causes the switch to close which causes the transmitter to send a signal that is received by a communications device, which prevents the recloser from reclosing.

    Abstract: A fault protection system for providing protection from fault current for components and devices on a lateral line proximate to a distribution transformer in a power distribution network. The system includes a single-phase recloser having a vacuum interrupter that is controlled by a controller. In one embodiment, the recloser has an insulating body that is molded in combination with an insulating body of a bushing that is connected to the distribution transformer. In this embodiment, the controller can be powered by a current transformer within the recloser. In another embodiment, the recloser is mounted to a utility pole separate from the distribution transformer, where the controller is powered by the low voltage side of the transformer and the current transformer is eliminated. An isolated power supply is provided between the transformer and the controller to provide voltage isolation.

    Abstract: A remote isolation system (10) for isolating an energy source from selected equipment (20) energisable by the energy source and controlled by a control system, wherein the system (10) includes a remote isolation station (12) for the selected equipment (20) to be isolated, the remote isolation station (12) being in communication with the control system for granting isolation on permissible request, the remote isolation station (12) having a human machine interface (100) for requesting an isolation of the control system, a human interpretable display (100) for indicating that an isolation approval has been granted from the control system, and an isolation switch (200) for communicating to the control system that an isolation is in effect. A remote isolation method and apparatus are also disclosed. The isolation system, method and apparatus are suitable for isolation of conveyors and other equipment.
