2 3728when the flux enters into saturation mode then what will be the secondary voltage of the normal t/f?....high or low ? explain ...how?
1 2116we are having 15kw and 3kw motor both can run in same time , instead of using copper we are using ug aluminium cable , 35 sq.mm is suitable for its current carrying capacity..?
1306Sir, Please tell me that how I will calculate the efficiency of rectifier. Because input is ac and output is dc. Is it right to put two unlike signal together.
2 2139Why we are always only used 11 kv. , 22 kv ,33kv in transmission line? Why not use 25, 55 ,65 kv ?
3 4190What is the effect of atmospheric pressure & Temp; on efficiency of motor? Why NGR(Neutral Grounding Resistor) is used in 132/11 KV Transformer & how? What is the use of Auto T/F in Grid Station?

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
