    Generally a current transformer is used mainly for measuring current and protection of the system which includes EHT and HT
    feeders or Power transformers in a substation or generating stations.

    Current transformers are used for measuring current in the circuit system in such a way that it merely reduces a
    large current flowing through its primary to a smaller current which can be read by an ammeter connected to its secondary.

    it electrically isolates the secondary circuit from the primary high-voltage circuit allowing measurements to be made,
    or protective devices to operate, safely.

    The primary circuit is largely unaffected by the insertion of the CT.
    The rated secondary current is commonly standardized at 1 or 5 amperes.
    For example, a 4000:5 CT would provide an output current of 5 amperes when the primary was passing 4000 amperes.
    The secondary winding can be single ratio or multi ratio, with five taps being common for multi ratio CTs.
    The load, or burden, of the CT should be of low resistance.

    In normal case a CT consists of a single core in High voltage side and 4 cores in low voltage side.

    Representation of windings of the secondary of the Ct is given as

    1S1(R) 1S1(Y) 1S1(B) 1S2(RYB-N) cores of each phases(R,Y,B) forms C core

    2S1(R) 2S1(Y) 2S1(B) 2S2(RYB-N) cores of each phases(R,Y,B) forms D core

    3S1(R) 3S1(Y) 3S1(B) 3S2(RYB-N) cores of each phases(R,Y,B) forms A core

    In the case of EHT feeders three secondary cores are used and the 4th one is taken as a spare and shorted.
    Three cores are categorized as
    1) A core – for Distance protection
    2) D core – for metering
    3) C core – for back up protection (over-current & earth fault)

    In the case of power transformers 4 cores are used as follows
    1) A core – for Differential protection
    2) D core – for metering
    3) C core – for back up protection (over-current & earth fault)
    4) AB core – for restricted earth fault protection
