trnaformer

Answer / koti

1. Star / Star
2. Low Voltage Wdg
3. Zero (Cos 90=0)

Answer / guest

the power factor of purely inducive load is lagging.

Answer / gaurav agarwal

1. star/delta
2. secondary winding

Answer / nadhagopal

star to delta
lagging for pure inductive
leading for pure capcitive

Answer / guest

in power supply transformers star delta conn. is prefered

Answer / praveen kumar gupta

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

Q3.A

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 want to put this query to SENIOR & EXPERIENCED ELECTRICAL ENGINEERS. 1)I want to know about the control circuit diagrams for control panels. I found it difficult to understand. Is there ant booklet through which we can learn the circuit diagrams? 2)I want to learn about conduiting, laying cables, preparing cable schedules and various techniques which is the part of building infrastucture(construction field). I don't have any experience in this area. I have experience in control panels only. that's why i am not getting any opening in building infrastucture (construction field).Can I get the job in this field as Trainee Engineer? How to enter this field? I need job in PUNE
