Over voltage, severe under frequency, or add too large of a secondary burden (the last is what typically happens).
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.
A current transformer is used for measurement of alternating electric currents. Current transformers, together with voltage transformers are known as instrument transformers.
Yes, certain types of relays can be activated by current 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.
By direct from the manufacturer! Current & Potential Transformers
Direct electric current cannot be used to operate D. Transformers.
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.

Transformer are passive devices thattransform AC to AC by magnetics and coupling. DC IS UNIDIRECTIONAL it does not change POLARITY. While it is possible to saturate a transformer primary it output cannot reflect the change since it has reached steady state
transformers cannot amplify!
Alternating.
low accuracy
I am aware that Class TPS current transformers have a Low Leakage Flux design
