Ade7880 evaluation board user manual

 · I found this equation in the ADE eval board user manual: R1 = R2 = 1/2 × /√2 × N/IFS. However I'm not sure if the N is the turns ratio or the CT current ratio which in this case is The turns ratio is not specified in the CT name plate. If I use the N as 10 Ifs as 5A (secondary full scale), I get a value of ohms.  · Ade Evaluation Board (com14) Driver License Details, datasheet, quote on part number: ADE The ADE device incorporates second-order sigmaintegrator, reference circuitry, and all of the signal processing required to perform the total (fundamental and harmonic) active, and apparent energy measurement, rms calculations, as well as. The ADE is a high accuracy, 3-phase electrical energy measurement IC featuring an adaptive real time monitoring (ARTM) harmonic engine. ARTM is capable of monitoring three user selectable harmonics, in addition to the fundamental. ARTM automatically tracks fundamental frequency and provides real-time harmonic measurement updates.

The evaluation board has been designed so that the ADE can be evaluated as an energy meter. Using appropriate current transducers, the evaluation board can be connected to a test bench or high voltage (V rms) test circuit. On-board resistor divider networks provide the attenuation for the line voltages. Hi!!! I am getting input ADC count for Vrms, Irms and frequency reading from ADE and Its same as with real value applied to that. But I don't know how to read power from power resisters given because there are many power register and I am confused which will give active/reactive and apparent power and what is the step by step procedure to get actual power reading?. ADE is suitable to measure active, reactive, and apparent energy in various 3-phase configurations, such as wye or delta services, with both three and four wires. This metering ICs provide system calibration features for each phase: rms offset correction, phase calibration, and gain calibration.
