摘要： Disclosed are apparatus and methodology for providing battery protection for devices operating in a battery supplied low-power mode. Micro controller operated devices (such as electricity meters) that may be stored for extended periods after manufacture and before deployment are provided backup battery protection by insertion of an overcurrent operable switch between the battery and the micro controller. A timer causes the micro controller to switch to a normal power mode after a predetermined time period during which no external supply voltage is provided. Normal power mode operation under battery powered supply only will cause the overcurrent switch to open, so as to disconnect the battery from the micro controller. Alternatively, instead of switching the micro controller to a normal power mode after a predetermined time period, the battery powered supply is shorted to ground using an internal switch of the micro controller, to achieve the same result of disconnecting the battery from the micro controller.

摘要： Apparatus and methodology are provided for measuring energy, particularly in a useful way for a multiphase system. Individual, like single-phase metrology blocks are provided to monitor energy in selected phases of a multiphase system. Individual data from a relatively upstream metrology block is passed to a relatively downstream metrology block, with the data stream being concatenated as the stream tracks from one metrology block to another. Energy data is coded as a predetermined small quantum of energy such that the last metrology block in a seriatim configuration of such metrology blocks may compute total energy consumption in the effective multiphase system by simple addition of the energy quantum data arriving at such last metrology block.

摘要： Disclosed are apparatus and methodology subject matters for providing improved functionality of a meter in a 2-way communications arrangement, such as an Advanced Metering System (AMS) or Infrastructure (AMI). More particularly, the present technology relates to methodologies and apparatus for providing load side voltage sensing for utility meters which preferably are operable with remote disconnect features in an Advanced Metering Infrastructure (AMI) open operational framework. The present subject matter provides enhanced capabilities resulting in improved functionality, increased safety, and greater economy vis-à-vis fraud detection for individual metrology components in an open operational framework. Meters per the present subject matter utilize a detection circuit, which is situated generally downstream of a remote disconnect functionality. Such detection circuit is able to sense whether voltage exists or doesn't exist at such relatively downstream, or load side location. Providing such functionality allows for: (a) verification that a remote disconnect switch did open subsequent to an instruction or command to do so, (b) identification of possible user fraud, as would possibly be reflected by the presence of voltage at a time when the remote disconnect switch is open, (c) verification that the remote disconnect switch did re-close after having been given an instruction or command to close, and (d) verification of lack of voltage present before re-closing such remote disconnect switch, which serves an important safety feature.

摘要： A Hall effect sensor or device may be used in a variety of embodiments, such as measuring current within an associated conductor by helping to measure flux density within a gap of a ferromagnetic power meter core, such as in a power meter. A high linearity interface for a Hall effect device is provided for minimizing offset effects without using complicated electronic circuits. First and second levels of modulation relative to line frequency are used to synchronize Hall effect device input switching circuits and feedback loops for improved elimination of offset signals or noise from the ultimate system output. The substrate of the Hall effect device may be connected electrically to an output pin of the Hall device or to a separate virtual ground to eliminate any effects caused by asymmetry of the voltage appearing in the channel relative to the substrate. The net effect of the high linearity interface is to eliminate any adverse effects to linearity of the system, especially at low magnetic flux levels where the output voltage of the Hall device would be relatively small compared to the offset voltage levels involved. The interface virtually eliminates adverse effects from operational amplifier input offset voltages, Hall effect device output offset voltages, and any common mode voltages.

摘要： A power supply system and corresponding methodology is provided for providing a self-protected power supply for use with electronic electricity meters. The self-protecting features are provided, in part, through the use of surface mounted resistive components corresponding to a resistor dropper portion of the power supply. The use of surface mount components also provides a general reduction in circuit board surface area requirements thereby providing a compact overall construction and provides economies with respect to reduction in manufacturing process steps. When the surface mount resistor divider is configured along with a half-wave rectifier, a low voltage DC supply is obtained from a direct connection to a much higher voltage AC mains source without requiring the use of coupling capacitors or transformers. Plural output voltages may be provided and capacitive filtering may be associated with the outputs. The use of a surface mount resistor divider in combination with surge protection elements helps to distribute any power surge over the power supply, which facilitates the use of less robust surge protection devices to achieve desired levels of protection.
