for a 11kv transmission line what capacity of CTs & PTs are
required?
Answer Posted / srinivasan.s
For 11KV line CT ratio was 1200A-600A-300A/1Amp
PT ratio was 11KV/110V
for 11KV CT's PT's minimum 3cores are available
generally 1'st core for metering
2nd and 3rd cores for protection purpose.

How do we find the rating of a transformer, if it got burnt badly.
In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
