I am working in 600MW power plant currently in erection
phase. I came along this term and want to know its meaning
in simple language, consider me naive!??
All motors shall be of energy efficient type EFF-2 as per
IS:12615/ equivalent IEC /
Design a cantilever type retaining wall to retain sand for
4m above the ground. The sand fall slopes at the rate of 1
vertical to 2 horizontal. The weight of sand is 18000 N/m3,
the angle of repose being 30. The safe bearing capacity of
the soil is 200 kn/m2 at 1/25m below the ground level. Use
m 15 concrete mix.
what is the difference between delta delta and star delta
why we use delta delta transformer since it need earthing
transformer for grounding?
How much difference can there be between HT & LT KWH unit
consumption at the same load?
can any body send me previous year model papers of BEL and
BHEL PLZ mail to firstname.lastname@example.org
This is reqd for a 1MW Solar power plant..We have 2DC
outputs from the solar panels Connected to 2INVERTOR
panels.. Output from invertor is 3ph,280v,500kva,50hz.These
are connected to individual ACB.This has to be stepped up
to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO
GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT
BY USING a single two winding 3 ph transformer 11kv/1250kva.
or (2)use the two outputs and connect to one three winding
transformer of above rating..Pls suggestwith details.
Which power will flow first if we switch on a motor Active
or Reactive? How?
