DM Equal to IME MINI CT

What are the basic differences between CT and PT?

These are the main difference between Current Transformer and Potential Transformer:
1.C.T is connected in series with HT line whereas P.T is connected in parallel in HT line.
2.In C.T, the No. of turns become inversely proportional to current whereas in P.T No. if turns become directly proportional to the voltage.
3.In CT the primary has one or more turns of thick conductor and the secondary has large no. of turns of the thin conductor whereas in PT the primary has large no. of turns of thin    conductors and secondary has few no. of turns of thick wires.
4.C.T is step-up instrument transformer which steps down the current whereas P.T is a step down instrument transformers which step down the voltage up to measuring range.

The DM-20 is a cost effective, compact current transformer. It is supplied with a DIN Rail adaptor, features a built in hinged terminal cover and has proven to be one of our most popular current transformers. N.B. No CT cable is supplied with this product, please select the optional extra below if required.
