General:

A Current transformer belongs to the series connected class of electrical apparatus. The system current passes through the primary winding of Current Transformer and sets up a current in its secondary winding. Except for a little deviation, this current is in phase with the primary current and bears a definite ratio with it. The little deviation is expressed in terms of the ratio error and phase error of the Current Transformer. Various international standards on current transformers specify the limits of these errors for various accuracy classes of the Current Transformers, the accuracy class depending upon the duty the current transformer is called upon to perform as also upon the type of instrument / protective device it is supposed to feed.

The following points need to be considered while selecting Current Transformers:

This is a ratio of the rated primary current and the rated secondary current and is usually specified as Rated primary current / Rated Secondary current. The rated secondary is determined by the rated current of the apparatus which is to be fed by the Current Transformers. For the range of current transformers, described here we have standardized on a rated secondary current of 5 Amps although Current Transformers with rated secondary current other than 5 Amps are also manufactured.
