Product Number: ADE9000
Hi, I’m using the ADE9000 metering IC in my product. I read phase wise energy registers AWATTHR_HI, BWATTHR_HI, CWATTHR_HI, AVARHR_HI, BVARHR_HI, CVARHR_HI, AVAHR_HI, BVAHR_HI, and CVAHR_HI in the same sequence inside the ISR whenever an EGY_READY interrupt occurs.
The EGY_TIME is configured for 999 samples. My ideal input load is 63.5 V, 5 A at UPF. While the measured power values are correct, I am observing a mismatch between KWH and KVAH in the energy (KWH > KVAH).
The behavior is frequent when switching test is done (power cycle is given continuously at an interval of 30sec). Note: The device is calibrated.
