WHEN THESE TRANSFORMERS WINDINS CONFIGURATION ARE USED? SPECIALLY EXPLAIN REGARDING STEP UP AND STEP DOWN KEEPING IN MIND.AND REGARDING LOAD ALSO. a.star to delta b.delta to star c.delta to delta d.star to star ALSO EXPLAIN WHY V USE 415/415 TRANSFORMERS IN TUBEWELLS?
ABB,
1 3914.if the vector group of two transformers is not same n tey r connected in parallel operation then what will happen?
ABB,
2 6105why transformer required and why not voltage directly supply from power generation to the applications
3 5403What will happen if 60 Hz rated transformer is connected to the supply of 50 Hz say 415 V (3-phase) step up to 3.3 kV...?? ?
