What is Procedure the procedure to select CT's & PT's in
66kV and above substation?
Answer Posted / kbonn
For example u have 100MVA transformer 66KV line
your CT ration 100,000,000/1.7320x66,000=874.77
so you can used CT ration 1000/1A

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
