A CT is used to measure current, and is NOT referenced to ground, and has very low primary impedance. A PT is used to measure voltage, is referenced to ground, and has a much higher impedance (since it is referenced to ground).
A current transformer pushes a ratio of primary current in the secondary. A potential transformer pushes a ratio of primary voltage in the secondary. Shorting a CT allows the full current the CT wants to push to flow. Shorting a PT makes it very difficult for the PT to produce rated voltage. To keep the voltage at rated value, the PT would have to push ~infinite secondary current.
The difference in between Ohms and Ohms CT is that in Ohms CT it has CT at the end.
The question is incomplete, because there are no mention about CT & PT ratios. 600VA 5 can not be CT ratio.
'CT' is used to designate current transformers, and 'PT' is used to designate potential transformers. A current transformer provides a ratio of primary current to the secondary. A potential transformer provides a ratio of primary voltage to the secondary. A power transformer (step up or step down) resembles a PT more than a CT.
Both are same.AnswerA 'PT' is a 'potential transformer', the preferred term in North America, for what is termed a 'VT', or 'voltage transformer', in Britain. Two names for exactly the same instrument transformer.
Multiplication factor can be derived from Meter CT, Meter PT, Connected CT and Connected PT values.
A ct is a step up transformer where as a pt is a step down transformer because both are used for measurement and protection purpose . current is stepped down if the secondary windings are more so we can obviously say thar ct is step up transformer
CT=========current transformer PT=========potential transformer these are the instrumental transformers.

the same as the difference between ct and k

Las Vegas is in the Pacific Time Zone (PT), and Dallas is in the Central Time Zone (CT). Therefore, Las Vegas is 2 hours behind Dallas.
