Metering device with control functionality and method thereof |
摘要 |
A metering device includes a first transformer that receives an analog waveform and generates a first stepped-down output signal; a second transformer that receives the analog waveform and generates a second stepped-down output signal; first biasing circuitry that receives the first output signal from the first transformer and generates a first digital signal within a first range, wherein the first biasing circuitry includes a switching device for switching between a first and second operational sub-range; second biasing circuitry that receives the second output signal from the second transformer and generates a second digital signal within a second range; and a processor assembly in communication with the first biasing circuitry, wherein if the first digital signal saturates the first operational sub-range, the processor assembly controls the switching device to process the first output signal in the second operational sub-range. |

1. A metering device operating on a secondary analog waveform output by an external transformer assembly receiving a primary waveform, the metering device comprising:
a first transformer, wherein the first transformer receives the secondary waveform and generates a first stepped-down output signal; a second transformer, wherein the second transformer receives the secondary waveform and generates a second stepped-down output signal; first biasing circuitry, wherein the first biasing circuitry receives the first output signal from the first transformer and generates a first digital signal within a first range, the first digital signal having a value proportional to the first output signal, wherein the first biasing circuitry includes a switching device for switching between a first and second operational sub-range; second biasing circuitry, wherein the second biasing circuitry receives the second output signal from the second transformer and generates a second digital signal within a second range, the second digital signal having a value proportional to the second output signal; and a processor assembly in communication with the first biasing circuitry, wherein the processor assembly executes operational software for determining if the first digital signal saturates the first operational sub-range, wherein if the first digital signal saturates the first operational sub-range, the processor assembly controls the switching device to process the first output signal in the second operational sub-range. |
