    Abstract: A method for monitoring a polyphase network includes the steps, repeated regularly, of: acquiring voltage measurements taken by voltage sensors of an item of electrical equipment, and producing current values of electrical parameters; accessing a reference table comprising a list of connection configurations each associated with a distinct combination of reference values of said electrical parameters, the list of connection configurations comprising configurations each corresponding to a combination of connection states for each phase (P1, P2, P3) and for the neutral (N); implementing an exploratory algorithm intended to explore the reference table to identify the current connection configuration.

    Abstract: A transducer formed of one or more electrode arrays is positioned in confronting relation and parallel to the plane of rotation of one or more rotating members. A binary interdial compensation value is generated to correct for errors in the mechanical misalignments of certain ones of the rotating members which would normally lead to ambiguities in the dial readings.

    Abstract: Apparatus for use in an automatic meter reading system for displaying meter encoder generated dial readings and detecting errors in response to information contained in the encoder meter dial readings. Errors are detected through interdial checking by comparing the angular positions of adjacent dial drive gears. When the angular positions of adjacent gears are not in the proper mechanical, or angular relationship an error is recorded.

    Abstract: A heat sensitive fault detecting and indicating system and method for a watthour meter is disclosed herein. The illustrated watthour meter includes a potential stator and a current stator both of which are mounted on a frame assembly, the assembly also having mounted thereon one or more permanent magnets and a rotatable disk assembly with disk rotation being recorded on the recording dials of a register assembly visible through the enclosing glass cover of the meter. The current stator includes a pair of current coils which coils have a heat sensitive fault detecting and indicating device associated therewith. The heat sensitive fault detecting and indicating device illustrated includes a layer of low melting point metal, such as tin, for example, which layer is covered by a sheath, such as a plastic sheath, for example, with predetermined portions of the sheath being thinned, as by embossing, for example, with a predetermined symbol or other indicia. When a current surge is experienced at the watthour meter producing sufficient heat at the current coils, the low melting point metal melts and penetrates the thinned area of the sheath thereafter indicating that a possibly damaging surge has been experienced by the meter. The indication that a surge has occurred is preferably made readily visible through the glass cover to facilitate meter monitoring.

    Abstract: Systems and methods for characterizing a device that operated to clear a fault in a power line, such as a power distribution system feeder, are disclosed. Characterizing the device may include receiving measured data corresponding to a current measured along the feeder proximate a substation bus, determining from the measured data that a fault has occurred in at least one phase and has been cleared, subtracting reference data from the measured data to estimate residual fault data, and estimating from the residual fault data a characteristic of the device that operated to clear the fault. The systems may include an Intelligent Electronic Device (IED) and a processor linked to the IED.
