ECN Forum Forums Technical Discussion Electrical Theory and Applications CT feedback, 0-5 Volt - calculate power in Watts

You posted "I have 3 CT's giving me a 0-5V feedback". If you have CT's you are getting current not voltage. If you have a 200/5 CT the multipler is 40.(200/5 = 40) Multiply the current reading by 40 for the total amperage. There are recorders that monitor voltage with PT's and Current with CT's and multiply the total to get the total watthrs and peak power in kw.
