Some embodiments of the invention include a method and system for metering an electrical grid comprising at least one processor executing instructions from a non-transitory computer-readable storage medium of an electrical grid fault detection system. In some embodiments of the system, the instructions cause a processor to calculate a prediction of whether power delivery to at least a portion of the electrical grid is functioning abnormally using voltage sensing devices coupled to at least one feeder, where one or more of the voltage sensing devices are responsive to a determination that the power delivery is functioning abnormally. Further in some embodiments, the determination includes the electrical grid fault detection system receiving at least one signal or voltage reading from the electrical grid based at least in part on a sensed or received voltage level or range of voltage level.

Wire down detection system and method

Device, structure and method for retrofitting a utility meter such as a gas meter with a retrofit module or for new installations to conventional meters so that it can be read remotely and so that retrofit may be accomplished simply by unskilled workers and without damage or alteration of meter. The method for retrofitting a meter of the type having shaft driven dial with dial index pointer and index cover involves removing the meter index cover to access the meter index dial pointer; attaching a magnet to the pointer so that it is carried in orbit around the pointer shaft to which the pointer is attached; and mounting a sensor to the meter adapted to sense the passage of the pointer-mounted magnet and to detect the orbit of index pointer; the attaching of the magnet and the mounting of the sensor being performed without removing the meter dial index assembly.
