In the case of a current transformer that would run a meter to 5 amps full scale with 300 amps on the primary, the manufacturer may label it as a current ratio of 300:5 ... - read more
For example: if the primery winding on the transformer were 250 turns and the 1250 turns on the secondary, what is the turn ratio? Well what you do is you take 1250 divide that by 250 will give you 5. So the answer would be 1:5 since 1 will be on the top of the 250 and the 5 would be on the top ... - read more
