VOLTAGE ACROSS PHASE TO NEUTRAL

Answer / alpeshkumar vaghela

as the equivalent voltage across the terminal is (1/1.73)th
of the line voltage

Answer / alok

because angle between two phase is 120 not 180 degree so we
found phase to phase value 1.732 times not 2 times so for
phase to nutral we divide it by 1.732 and get less voltage
compare to ratted line value.

Answer / prakash suhane

In star connection, net resistence is copratively low hence
you found low voltage drop.

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
