it is used only for protecting our equipment from the
thunder light. All current bypass through this.
if we use the coil/core then there will be high reluctance
and due to have an rolling iron there will be eddy current
and hysterisis loss

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
