no direct current is not used in Transformers. the reason is that, if dc is used, there would be no counter emf to oppose it in the primary winding.
since the constant flux will be flowing in the dc, there would be no rate of change of flux. as a result, the total current will be applied at the primary winding only. this results in the burning of the total primary winding.
=====================================
The practical application is:
If transformer input is DC, transformer output is smoke.
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.
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.
Some possible answers are: a battery (which produces direct current) or a generator of electricity generator, such as a dynamo (which produces direct current) or an alternator (which produces alternating current).
transformers cannot amplify!
Alternating current. Direct current is used in batteries.
Direct electric current cannot be used to operate D. Transformers.
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.
A current transformer is used for measurement of alternating electric currents. Current transformers, together with voltage transformers are known as instrument transformers.

DC aka direct current
It means Current Transformer is used for measurement of electric currents, together with voltage transformers

Not directly, as MC instruments are direct-current instruments, whereas instrument transformers only work on a.c.
It comes out as direct-current electric power.
