I have a bunch of generic CT’s that came with a home automation system from ‘Openmotics’. they are 12Aac, 25Aac and 50Aac. I have about 20 of them so would be good to use them. Unfortunately they have no model number, except for one which i found on a site (25Aac) and the specification indicated !:3000 ratio which I presume is the number of turns.
Is there some way of determining or calibrating like you can for power reference?
Could I compare the output from one that you have supplied?
simple minded sorry
kind regards daniel
