Sir,
As we are looking into the possibility of using MSP430F67641A AND SIMILAR THREE PHASE &SINGLE PHASE DEVICES IN OUR PROJECT, can we know if we can get some application support on these devices during the course of our development.
Regards
VTC
Hello,
Did you read the Class 0.5 Three-Phase Energy Measurement System Design Guide? In the design guide, there are e formulas used for the voltage, current, energy, and temperature calculations shown in below.
And these formulas are implemented in the software TIDM-3PH-ENERGY5-ESD Software.
For the calibration procedure, please refer to section 7.3.2 in above design guide.
Because the power is computed by above formula (4), not Vrms*Irms. You need calibrate the power.
The hardware also can be found in the reference design page.
