Hi dear support,

I have question about converting read value from register to real value of meassured active, reactive, apparent power and similiar registers. Which equation or procedure is used for this?

For calculating URMS and IRMS i followed equation ona page 8 of AN-1118, where you calculate constant for known voltage/current, multipled constant and read value from URMS/IRMS register give you a real value of voltage/current.

Please help me because I don't know which is right approach for this problem.

Best regards, Darijo

Hello Vladopanj,

Are you referring to the total active, reactive, apparent power or the active, reactive apparent power consume with time?
