what is the ciruit diagram of transformer vector grup test?
Answer Posted / thiyagarajan
it will depends upon the transformer vector group for eg
your having ydo means the primary power is in phase with
the secondary if yd11 means secondary is leading primary by
an angle of 30degree yo can draw vector diagrams as per
their phase angle then making short to any of the same
phases in primary and secondary by deriving you can apply
voltage across primary and measrure voltages as you will
get some conditions based on vectors

if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
