what is means of ALF,kPV(min),lexc(max)at Vk,Rct@75 degree
centrigate ohm in current transformer name plate?
Answer Posted / santosh89
ALF--accuracy limit factor(ratio of nominal over current to the rated current)
KPV--knee point voltage(secondary voltage must be less than KVP so that ct accuracy will not hampered)
KPV=k.Is(Rct+Zs) where Rct=resistance of secondary winding at 75 c
