One example includes a relay device that is comprised of a galvanic isolation barrier, a protection control and power extractor, and an electronic switch. The galvanic isolation barrier is coupled to an input of the relay device and receives a switch control signal and outputs another switch control signal. The protection control and power extractor is coupled to an output of the galvanic isolation barrier. The protection control and power extractor extracts power from a power supply coupled to the relay device. The protection control and power extractor is responsive to the other switch control signal and generates a protection signal in response to a determination of an operating parameter of the relay device. The protection control and power extractor further outputs an electronic switch device signal based on the generated protection signal.

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.
