A system for the configuration of power meters.

Network configurable system for a power meter

A current switch is automatically calibrated when a flow of electric current is initiated in a power cable.

Current switch with automatic calibration

A modular metering system comprises a data processing module, a current module and a voltage module. The current and voltage modules include sensor memories characterizing the respective current and voltage sensors facilitating assembly and repair of the metering system.

High density metering system

A power monitoring system with multiple sensors for electrical panels providing power through multiple electrical conductors. The power monitoring system preferably includes at least four sensors supported in a fixed spatial relationship on a support. The sensors include openings through which electrical conductors may be extended.

Power monitoring system

The computational resources of a digital power meter can be reduced by utilizing an interrupt requested in anticipation of interrupt latency to perform real-time tasks, an approximation of a root mean square load current at an earlier time to compensate for a phase shift between the load current and the current transducer output, and an amplitude that is neither zero nor maximum to distinguish the cycles of a harmonically distorted waveform.

Power meter

The data storage and processing resources required for an electric meter are reduced by basing the selection and application of phase error correction on a root mean square load current flowing through the meter.

Electricity metering with a current transformer

A power monitoring system for electrical panels providing power, received from one or more power sources, to multiple current conductors. The power monitoring system preferably includes a plurality of sensors affixed to a support. A portion of each sensor defines an opening through which a current conductor may be extended.

Separable toroidal segments reduce the size of a sensing transformer that can be installed on an electrical conductor while connected to a device.

Split core sensing transformer

A current sensor that includes a pair of segments. Each of the segments includes magnetically permeable cores that can be joined together. A winding is used to substantially encircle one of the cores.

Current sensor that includes a pair of segments

A power monitoring system for electrical panels providing multi-phase power, with multiple current sensors. The disclosed power monitoring system preferably determines the instantaneous power provided to each of multiple loads by sensing the potential and phase of each conductor that supplies power to one or more of the respective loads.

Simplified power monitoring system for electrical panels

An electricity metering method and apparatus is provided for determining the phase of first waveform relative to a harmonically distorted, second waveform having cycles temporally distinguished by an occurrence of an amplitude that is neither zero amplitude nor a maximum amplitude of said waveform.

Method and apparatus for phase determination

A power monitoring system comprising a first current sensor suitable to sense first changing electrical current within a first conductor to a first load and a first conductor. A second conductor sensing a first voltage potential provided to the first load. A power monitor superimposes a first signal on the first conductor and first current sensor such that the first signal is sensed on the other of the first conductor and first current sensor. Associating the first voltage potential with first changing electrical current in the power usage calculation of the first load.

Power monitoring system that determines phase using a superimposed signal

An interrupt request is asserted in anticipation of a period of latency preceding preparedness of a power meter data processing device to sample a voltage or current enabling the use an interrupt to control the data processing device's performance of real-time sampling in combination with other tasks related to the power meter's operation.

Prioritized interrupt for waveform measurement

A power monitoring system for electrical panels providing multi-phase power, with multiple current sensors. The disclosed power monitoring system preferably includes a support, at least four sensors defining an opening through which a wire may be extended, with the sensors being supported by the supports in a fixed spatial relationship.

A system for identifying the relative location of devices.
