Answer Posted / kartheear
3 line PT's prot./meter in 11kv side(before side)
3 prot/meter. CT's at 11kv side(before side)
3 line PT's prot./meter in .433kv side(after side)
3 prot/meter. CT's at .433kv side(afterside)
In each CTs & PTs,ther wil b a seperate core for metering n
protection,dont get confused with the windings in assuming
tat this is for ef,oc and differential,get a CT/PT wit both
metering n protection whatevr d core is depends upon our
application in relays.
