transformers parts & function of each parts

Answer Posted / s.m.jalal atta

help oil filling this is situated upper portion of the
power transformer . mainly these are cylindrically
shapped...
2) TANK - basically this is a container used to keep
windings(both) and cooling oil.
3) BUTCHHOLZ RELAY - this is a protecting device used to
protect our transformer windings . this is a double ended
device one end is conneced to conservator other is
connected to tank. there are two windings inside the relay
one for detecting oil level goin to empty and other is
connected to a alarm circuit for warning
4) BREATHER - Breather is a device used for absorb the
moisture content of a oil and sucked air
5) SILICA JEL - it is a chemichal matarial these are the
only one main component inside the breather basically
silica jel is a brown coloured one after the absorbtion
silica jel become pink
6) OIL LEVEL SCALE - this is a ordinary part situated on
the side of the conservator for proper oil checking oil
tank wants a specific amout of oil
7) PRIMARY WINDING - in Power Transformers primary
winding is the main element for external connection
from where the power is connected to thi winding
8) SECONDARY WINDING - is a another winding to reduce
power (for step down purpose)
9) DRAIN VALVE - is used for taking damaged oil from the
oil tank for the proper oil collection this valve is
situated under the oil tank
10) PORCELIN BUSHING - This is a outer unit , this is used
to prevent unwanted leackage of electricity
11) RADIATOR - This device is used to keep the cool oil
(filled oil)

We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?

why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
