Answer Posted / satyapal prajapati
when ac is applied on the t/f primary there is change in
flux in primary. due to this change in flux an emf induced
in the primary which opposes the applied voltage according
to lenz's law called back emf.
but when we apply dc to the primary there is no flux
change and no back emf. the applied voltage damage the
primary winding of t/f. and there is no voltage in the
secondry.

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.

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?
