Abstract:
1. An arrangement for controllably disconnecting a utility power service from a load, comprising: a utility meter housing including metrology circuitry configured to generate metering information regarding electrical power provided to the load; a service switch configured to controllably interrupt a connection between the utility power service and the load; an electrically-powered source of motive force configured to cause the service switch to controllably interrupt the connection between the utility power service and the load; an energy storage device configured to provide power to the electrically-powered source of motive force; a charging circuit configured to provide charging energy to the energy storage device, wherein the energy storage device is configured to provide sufficient power to the electrically-power source of motive force after being at least partially charged by the charging circuit; a control circuit configured to provide a first signal to a first switch operably connecting the energy storage device to the electrically powered source of motive force, and to provide a second signal to a second switch operably connecting the charging circuit to the energy storage device, wherein the control circuit is configured to receive a disconnect command signal, and to provide the second signal and the first signal in sequence responsive to receiving the disconnect command signal.
