The current rating of Transformers vary widely as well as the types (step-down, etc.....). So depending on the use, the primary power, and the secondary power, the amp load will change. More in general current is amps, if your transformer has say 1Kva on it then that tells you the apparent power the transformer can handle. As a side note a lot of transformers are rated in VA or KVA and that is a combination of volts and amps (apparent power).

What are the functions of current transformers and the difference between current transformers and voltage transformers?
To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
Who would need to utilise current transformers?
A current transformer is used for measurement of alternating electric currents. Current transformers, together with voltage transformers are known as instrument transformers.
Can we drive relays by current transformers?
Yes, certain types of relays can be activated by current transformers.
Are Transformers used in circuits with Direct Current?
No. Transformers are used in circuits with Alternating Current. Transformers work on the principle of a "changing" magnetic field inducing a current in a conductor, and you don't get that "changing" field with Direct Current.
Acids conduct electric current by forming what?
By direct from the manufacturer! Current & Potential Transformers
Current Transformers Manufacturers?
Macroplast Transformers is a leading Current Transformers Manufacturers in India. Current transformers are devices that transform higher current value to lower current value. Current transformers provide galvanic isolation from the voltage on the primary winding while simultaneously creating a power signal that has been converted to a standard level, which in turn permits the use of standard measurement instruments and relays.

Can a current transformer be used for current amplify?
transformers cannot amplify!
What kind of current do transformers utilize?
Alternating.
What are the limitations of current transformers?
low accuracy
What is the difference between Class TPS and Type X Current Transformers?
I am aware that Class TPS current transformers have a Low Leakage Flux design
Does the battery method have any limitations on testing the transformers polarity?
yes its does the higher the current will blow out the transformers
Why does the national grid use AC current?
transformers
