I am trying to Calculate Current of 1HP Motor uses with Motor Starter Box. Initially when Motor is started i can see current shoots upto 20-22A on analogue meter in starter box.
I want to measure this Current Continously while the motor is in operation.
For that purpose i have purchased 30A / 5A (CT) (12 Turns wound on CT) AC Current Transformer 30/5 A (Two turn Primary)
on 30A AC load it will provide me 5A AC output on secondary (CT output). Burden Capacity is 2.5VA. I am confused with burden resistor calculator and how can i interface CT with ADC of atemga32.
Please can anyone help.
