I have two AC generators, the first rated 2680KVA for 380V/4345A/pf:0.7 and the second rated 3461KVA for 5500V/363A/pf:0.8. I want to parallel the two generator to a bus. The second generator passes through a transformer to down the voltage to 380V and a part of its power goes to another bus so that it's only a part of the total power of the second generator taht goes to the considered bus. I have two Basler DECS100 AVR regulator. How can I make the synchronization ? What others equipments must have ? cst   0  314
when an induction motor runs on load.at that time if we reduce the supply voltage the current increases.But when it runs without load,if we reduce the supply voltage the current also reduced.why?.i checked it practically also. birla   1  1212

If a 3 phase transformer is a 500 kva using the formulae 500kva= 500000/433 x 1.732 = 666.71amps does this mean that each phase on the secondary side is 666.71 saffron   3  4018

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 346
