The purpose of a choke is to provide a ?

Answer Posted / manoj k k

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.

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
