calculate multiplication factor of a trivector meter with
line ct ratio 200/5A, line PT ratio 11000/110V and meter CT
ratio 200/1A and meter pt Ratio 11000/110V.
Answer Posted / jaskanwar
In a CT PT connection if there is a LTCT meter of 200/5 installed instead of HT meter of -/5 A . Then what will be the MF for this situation.
CT PT = 10/5 A

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
