it is a relay that checks for current balance between the
primary and the secondary side of a transformer.it is also
used in other components of the power system like to
protect cables.it is also known as a unit protection as it
does not discriminate with any other protection schemes.the
ct secondary currents that circulates in the coil of this
relay from primary and secondary of the transformer
cancells each other when the system is healthy.when the
