|what is the voltage of insulation megger that should be
used for measuring the resitance of 66kv equipments.
starter used to
dol starter do not
it,so why we use
|hi frienda We have 750kva cater pillet dg set we are fasing
one diffrent proublam in dg we are start dg set after one
mint applying load around 450a load but dg was run 3 Or 4
mints after 3 mints dg was shuding down automatic how to
face this proublam pls tel any budy
|At site, we have 30Kw motor (3 phase, 400V,50Hz) and FLC
54A as per the nameplate. At the time of starting it draws
840A instead of 390A (7.2%). As per the data sheet also its
390A starting current. it thru a dol starter from the MCC.
can anyone tell what is the problem in the motor
|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 should the transformer connection of a 11/220 kV step up
and 66/11 kV step down transformer ?
|I want to know if it is possible to use Variable Frequency
Drive to reduce the current required for starting a motor?
|what is an rmu?its circuit diagram.functions
|We in my plant one of the transformer showing neutral to
earth voltage is 22V how to solve it
|whether Transformer is singly excited or doubly excited machine?
|how to calculate the cable size for 500 kva transformer?
|how to calculate lux level in out door (yard lighting)
please expalin with a example
