I am using ADE9153A IC and I am able to measure VRMS, IRMS and PF.
Can you please guide me how to measure THD using ADE9153A energy meter IC and how to find the calibration factor for active and reactive power.
ADE9153A is not design to provide THD. You need to perform it separately.
Please, have a look at ADE9000 and ADE7880. Theis devices have been design to provide Harmonic Monitoring Functions
Thanks for your response,
Is there any method to calculate THD ?
