The %impedance of the transformer reflects the eqivelent
circuit parameters of the transformers however, the way its
named can be a bit confussing.
Remember that the %impedace is infact the percentage
voltage drop at full load compared to No load condition.

Where voltage are high and current to be interrupted is low the breaker preferred is:

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
