    摘要: A bistable relay may include a pair of contact arms. Each contact arm is configured to have a first end and a second end, such that, when the relay is in the closed position, current flows from the first end to the second ends of each of the contact arms, and when the relay is in an open position, current does not flow from the first ends to the second ends of the contact arms. The relay further includes a motor, a pair of springs, a pair of cams driven by the motor, and a linearly actuating member configured to move the contact arms from the first configuration to the second configuration, the member including a cam follower surface.

    摘要: An electronic energy meter senses input voltage and current signals and processes the input voltage and current signals to generate measurements of multiple types of power. The meter comprises a processing system for selecting one of the multiple types of power and defining the same as the selected type of power. The processing system also generates a pulsed test signal representative of a magnitude of a measurement of the selected type of power for testing the operation of the meter. The meter further comprises a communications interface coupled to the processing system for transmitting the pulsed test signal from the meter and for receiving signals from sources external to the meter. Selection of one of the multiple types of power can be achieved by the meter receiving, via the communications interface and from a source external to the meter, a communications command identifying a selected one of the various types of power. The communications interface may comprise an optical communications port.

    摘要: A 2-element, three voltage connection electronic energy meter is disclosed for measuring 3-phase electrical energy supplied by a 4-wire delta service without external potential transformers. The meter employs non-isolating voltage sensors for sensing the line voltages and includes and an automatic service type detector and isolation detector. The meter generates voltage and phase angle measurements for each of the two voltages sensed by the meter. The service type detector compares the phase angles to automatically determine the service type supplying the electrical energy to the meter. The isolation detector compares the two voltages to automatically determine whether or not the installation includes external potential transformers. If the service type is a 4-wire delta service and no external potential transformers are used at the installation for isolating the voltage signals, the meter doubles the voltage measured over the first of the two elements when generating power measurements.
