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.

why current transformers are used?

current transformers are used for metering and for protection purpose

can we drive relays by current transformers?

yes, certain types of relays can be activated by current transformers.

can transformers be connected in parallel?

yes, we can connect transformers in parallel. for this operation we should know the polarity of the transformers. if we connect transformers in parallel the total output current is equal to the sum of the 2 transformers secondary current.

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.

what is the difference between class tps and type x current transformers?

why you step up or step down voltage why not current?

the current is automatically stepped up or down when the voltge is stepped down or up by a transformer.most transformers are designed for a constant voltage, and the current varies depending on the load. current transformers are also made to detect the current in a power cable so that it can be measured.another answerit's a misconception that transformers step current up or down (with the exception of current transformers, that is!). transformers step voltages up or down. the secondary current is determined by the load. if there is no load, then there is no secondary current; if there is a heavy load, then there will be a heavy secondary current.the secondary current then determines the primary current, because the primary power must match the secondary power (ignoring losses), so if the secondary current increases, so must the primary current. the current itself isn't stepped up or down.> normal transformers work with constant-voltage supplies and are designed to step the voltage up or down, and the current is incidentally stepped down or up in the same ratio as the voltage.current transformers are designed to step current up or down (usually down), and are used most commonly to sample the current in power conductors.
