|why we use perllel conection system in the wiring?
|why the field winding of synchronous machine is excited by dc source
|why the rating of dc generator is in kw where as rating of
alternator is in kva?
|which motor gives constant speed?
|We have a 33/11kv switchyard having 12.5 MVA power
transformer. We export & import power through this
transformer. When we export power, the PF will be depend on
GRID PF & when we import power the PF will be depend on our
load PF. but the problem is that,when neither we export nor
import but our 33KV vCB is in close position,our meter read
the power factor 0.14 to 0.25 at that moment. So how can be
we improve the power factor at that moment.
|What is the distance between body earthing and neutral
|whytransformers rating in KVA?
|Using 11000V/433V,3 ph,50Hz,500 KVA, what is the maximum
capacity of motor in KW that can be connected and started at
a single moment? Also explain about any calculations and
formulas used in deriving the same.
|why the neutral of power transformer is always earthed?
|What is the purpose of Rotor earth fault relay and How to
test the Rotor earth fault relay in generators and What is
|What happened when we give 2 phase supply to a 1 phase
equimpent. It's effect on equipment's efficiency and life?
|plz tell me in my que,how to connect thw electrical wirening in house?
