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

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]
