Abstract:
1. An electrical panel metering device comprising: a housing including a front face panel configured to facilitate mounting of the panel metering device in a cut-out of an electrical panel; at least one sensor configured for measuring an electrical parameter; at least one analog-to-digital converter coupled to the at least one sensor for converting the measured electrical parameter to a digital signal; a display disposed on the front face panel of the housing for continuously displaying at least one electrical parameter; at least one processor configured to receive the digital signal, calculate an amount of energy consumed for revenue metering and generate a plurality of pulses signal indicative of the amount of energy consumed; and a test pulse circuit configured to receive the plurality of pulses from the at least one processor, wherein the test pulse circuit includes an LED disposed on the front face panel of the housing to generate a subsequent plurality of pulses from the received plurality of pulses for verifying the accuracy of the panel metering device with an external reference standard device.
