WHEN I AM CONNECTIN TWO ELCB IN PARALLEL.ONE ELCB
TRIPPED...HOW IT HAPPEND??

Answer Posted / purushotham

the ELCB's are connected in parllel, so the voltage in the
ckt is equal but current is diff. so if one coil trips the
ckt will works on second ELCB and total loading depends on
that second ELCB.

True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)

I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?
