I am using ADE7878 for 3 Phase Energy meter purpose. I have calibrated 3 voltage channels. Now, i need to calibrate current channels.
Actually I am using 5 A : 333 mV Current transformer. 1,5 mV CT output is given to ADE7878 Current channel ADC inputs through filter circuits (I didn't use the R1 and R2 burden resistors because I have CT current to voltage ).
what is the configuration that I need to do to have a correct IARMS value ?
what is the method that I need to use in order to calculate a AIGAIN register value ?
Please tel me how to solve this.
Waiting for your reply.
