Current Transformer | CT burden calculation | Selection of CT | details | animation | video part 2

Current Transformer or CT is an important component of Electrical power system. It is used for measurements of current and giving juice to the relays for protection. Current Transformer basically steps down the current so that it can be fed to any meter or relay.

current Transformer have some parameters like Class, ALF or accuracy limit factor, ISF or instrument safety factor etc. They have their own function to play.

Overall ration of CT determines how accurately the CT will work. Selection of lower Ratio causes over load, where as selection of higher CT ratio causes less sensitivity of the circuit.
