|what will happen if the bus PT fuses are accidently removed
from the circuit in 6.6kV feeder?
|How we calculate the spacing between the conductors in 11,33KV
|What happens if 25 Hz frequency is applied for 400/200,50 Hz
single phase Transformer.Will Voltage increase ?
|WHAT IS MEANT BY BTU OF AIR CONDITIONERS.
|what will happen to the core losses if we perform the open
ckt test on high voltage side of a transformer ?
|We have a 12MW power plant & we inject 5-6MW power to
Orissa GRID. For this we have a 33KV/11KV switch yard
having 12.5MVA power transformer. Some times we draw power
during emergency. It is observed that during Export or
Import for load less than 500Kw the power factor is
decreasing to 0.3 . This is happening only during export or
import. During island condition TG power factor OK.Our
capacitor bank is provided with our Power plant auxilliary
load. Please suggest how I can we improve our power factor
during low load (GRID).
|Is there any difference between load based power plant and
coal based power plant?
|for a 5hp motor to operate from 100kva generator ,what size
of cable required in sqmm.
|what will be the motor terminal box connection arrangement
(star or delta). on what basis it decided?
|why synchronous motor is not self starting
|is KVAR (not reverse power) relay necessary to protect from
excitor field failure on a brushless, synchroneus generator?
Some people with previos experince tell me no but the
manufacturers tell me it is designed for that purpose.
Is it that it is only necessary for brushless generators
and not the older style with the slip rings and brushes?
|what is AB switch???
