our company have 750 kva oil transformer.still we have
facing a problem that is when voltage is 11.5 kv coming
from HT side then LT-side voltage is 420v or above at tape
1.please give me best solution to decrease the voltage
Answer Posted / k.prakashchandra
From the data furnished by you ,it appears that Tap No.1 is
the normal position as there is 5% rise in both primary and
sec voltages, for 11KV/400V Tr

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
