in power supply transformers star delta conn. is prefered
| Is This Answer Correct ? | 3 Yes | 5 No |
1. Star/Delta Type of transformer connection is preferred
in case of power supply transformers.
2. In a power transformer usually Low Voltage winding is
closer to the core
3.The power factor of a purely inductive load is Lagging
| Is This Answer Correct ? | 2 Yes | 4 No |
Answer / moloy dey
1. In case of supply transformer DELTA/STAR is used to
ensure 440[Ph to Ph] and 220 [Ph to N] both type of consumers.
2. (A) Primary winding stays close to the core.
3. The power factor of a purely inductive / capacitive load
is always (A) Zero, Hence, the power drawn by a
pure/loss-less inductor/capacitor is VxIx'0' = '0' [Zero]

I have connected 04nos. earthings to a transformer through 04nos. earthing pits seperately. 02nos. earthings are connected to T/F body, and 02nos. earthings are connected to T/F neutral.T/F capacity is 2000KVA, 11KV/415V. But after completing of 02 years successful operation ,we are facing following problems- 1. CT/PT occured blast one time 2. HT cable box occured blast two times 3. One body earthing strip and one neutral earthing strip of transformer are overlapping at some places. Whenever these two strips are pressed at overlapped points, they made spark. What is the reason of spark? Please explain the reason & rectification of above problems
