Abstract
A recloser for a distribution system includes a current sensor configured to measure an operating current of a distribution system. A controller is connected to the current sensor. The controller has at least one processor. A circuit interrupter is connected to the controller and configured to open a circuit to interrupt power in at least a portion of the distribution system. An RFID reader connected to the controller, the RFID reader configured to receive data from a user. The controller is configured to trigger the circuit interrupter to open the circuit in response to a detected fault current. The fault current is determined based on a selected fuse curve.

A recloser for a distribution system comprising:
- a current sensor configured to measure an operating current of a distribution system;
- a controller connected to the current sensor, the controller having at least one processor;
- a circuit interrupter connected to the controller and configured to open a circuit to interrupt power in at least a portion of the distribution system;
- and
- an RFID reader connected to the controller, the RFID reader configured to receive data from a user,
- wherein the controller is configured to trigger the circuit interrupter to open the circuit in response to a detected fault current and wherein the fault current is determined based on a selected fuse curve.
A distribution system fuse device comprising:
- an insulator body having a weathershed;
- a support bracket extending from the insulator body;
- a hood connected to the insulator body, the hood having a hood contact;
- a hinge member extending from the insulator body;
- and
- a recloser pivotally connected to the insulator body by engagement of a pivot with the hinge member, the recloser having,
- a current sensor configured to measure an operating current of a distribution system,
- a controller connected to the current sensor, the controller having at least one processor,
- a circuit interrupter connected to the controller and configured to open a circuit to interrupt power in at least a portion of the distribution system, and
- an RFID reader connected to the controller, the RFID reader configured to receive data from a user,
- wherein the controller is configured to trigger the circuit interrupter to open the circuit in response to a detected fault current and wherein the fault current is determined based on a selected fuse curve.
A method of setting the operating parameters of a controller for a distribution system fuse device comprising:
- emitting a signal from a first RFID device, the signal containing fuse curve data;
- receiving the emitted signal at a second RFID device;
- extracting the fuse curve data;
- and
- adjusting the operating parameters of a controller based on the fuse curve data.
