Abstract: Electricity service may be safely remotely connected to a site by a network computing device, such as an electricity meter, even when the network computing device is not accessible at the site. The network computing device may include a service switch capable of connecting electricity service to a site, a communication module capable of receiving commands to connect or disconnect electricity service, and a safety mechanism to monitor a circuit internal to the site and to prevent the service switch from connecting electricity service to the site while a potentially unsafe condition is detected.

Abstract: A load-side voltage detection module for a metrology device includes a plurality of first resistors electrically coupled to a first load-side terminal, the first resistors being in series, a plurality of second resistors electrically coupled to a second load-side terminal, the second resistors being in series, a voltage divider electrically coupled between a first line-side terminal and a second line-side terminal, the voltage divider creating a reference voltage for the load-side voltage detection module, and a pulse generator to generate a pulse based on detection of voltage, the pulse indicating a voltage on at least one of the first load-side terminal or the second load-side terminal, above at least one threshold.

Abstract: A method, apparatus, and system for providing an input overvoltage protection are disclosed. A voltage monitor may monitor input voltage to an electricity meter and output a reference voltage associated with, or based at least in part on, the input voltage. A ground switch may electrically connect a first ground to a second ground allowing current to flow from the second ground to the first ground and charge a bulk capacitor up to a predetermined level when the reference voltage is less than or equal to a threshold voltage, and electrically disconnect the first ground from the second ground and prevent from charging the bulk capacitor higher than the predetermined level when the reference voltage is greater than the threshold voltage.
