A choke is a coil of insulated wire, often wound on a
magnetic core, used as a passive inductor which blocks
higher-frequency alternating current (ac) in an electrical
circuit while passing signals of much lower frequency and
direct current by having an impedance largely determined by
reactance, which is proportional to frequency. Chokes are
typically used as the inductive components in electronic
filters.

how can i use REF and diffrencial relay both in 1 CT core for transformer protection?
