摘要： A transient reducing capacitor switching device that switches grounded capacitors into a multi-phase power line, wherein each phase of the line carries an AC voltage signal that cycles its polarity. A first switch is associated with a first grounded capacitor, a second switch is associated with a second grounded capacitor and a third switch is associated with a third grounded capacitor. A switch controller switches the first capacitor into the first phase of the power line substantially when the voltage signal in the first phase crosses zero potential. The switch controller has a delay that delays at least one-quarter of one cycle after the first capacitor was switched into the first phase, then switches the second capacitor into the second phase of the line substantially when the voltage signal in the second phase crosses zero potential. The switch controller then delays at least another one-quarter of one cycle after the second capacitor was switched into the second phase, then switches the third capacitor into the third phase of the line substantially when the voltage signal in the third phase crosses zero potential.

摘要： The present invention includes an electrical utility meter operable to measure power consumption. The method detects and compensates for one or more wiring errors that affects the power consumption measurement of the electrical utility meter. The method includes the steps of: obtaining measured phase angle data for a plurality of phases in a polyphase electrical system; periodically performing one or more diagnostic tests using the measured phase angle data to determine whether a wiring error is present, automatically adjusting the operation of the electrical utility meter to effect a compensation for the wiring error, said compensation increasing an accuracy of power consumption measurement of the electrical utility meter. The meter is operable to detect and compensate for wiring errors including polarity errors and cross phasing errors. According to another method of the present invention, the meter is operable to determine automatically the service type to which it is connected.

摘要： Apparatus for injection voltage compensation in series into an electric power line includes an inverter or other controlled voltage source which wye connects the secondary windings of a three-phase transformer to the load end of the electric power line. The transformer, which could already be present for meeting load requirements, has its primary winding connected to the source end of the electric power line and sustains the saturation currents rather than the inverter in response to faults on the source side of the transformer. Preferably, a three-phase inverter with a common dc link is used. For active power line conditioner (APLC) action, a second, also preferably a three-phase, inverter is connected in parallel to the load end of the electric power line and to the common dc link. This parallel inverter provides harmonic and reactive power compensation and also supplies the real power requirements of the wye connection inverter.

摘要： An electronic utility meter includes a sensor module and a removable measurement module. The sensor module connects to the electrical system of a facility and includes voltage and current sensors. The voltage and current sensors is operable to receive voltage and current signals from the electrical system and generate measurement signals therefrom. The sensor module further includes an electrically safe interface. The removable measurement module includes a measurement circuit operable to receive measurement signals and generate energy consumption data therefrom. The measurement module also includes a device for communicating information relating to the energy consumption data. The electrically safe interface of the sensor module operably connects the voltage and current sensors to the measurement circuit, and further prevents physical contact of a human operator with the received voltage and current signals from the electrical system when the measurement module is removed from the sensor circuit.

摘要： A controller for a voltage regulator has an input keypad for designating selected operating parameters of the voltage regulator. The keypad is formed with a dedicated function portion and a menu navigation portion, and the parameters are divided into first and second categories. The controller has a display for displaying the parameters, and a computer is connected to the input and to the display for controlling the display in response to activation of the keypad. Any parameter in the first category can be displayed on the display by activation of the dedicated function portion of the keypad. Any parameter in the second category can be displayed by activation of the menu navigation portion. The menu navigation portion can optionally also be used to control display of parameters in the first category.

摘要： A utility meter which provides multiple concurrent registering of commodity consumption data includes a source of commodity consumption signals (12), a measurement circuit (14), and a registering circuit (16). The source of commodity consumption signals is coupled to provide commodity consumption signals to the measurement circuit (14). The measurement circuit (14) is operable to generate commodity consumption data from the commodity consumption signals. The register circuit (16) is operably coupled to the measurement circuit (14) to receive the commodity consumption data therefrom. To this end, the register circuit (16) includes a memory (20) and a processor (18). The memory (20) stores a first set of parameters corresponding to a first metering mode, and a second set of parameters corresponding to a second metering mode. The processor is operable to generate first metering information by performing a metering routine a first time using the first set of parameters and the commodity consumption data, generate second metering information by performing the metering routine a second time using the second set of parameters and the commodity consumption data, such that the processor generates the first metering information and the second metering information on a concurrent basis.
