Answer Posted / yunus pinjari
Electrical power is generated in DC and while transfer this
power to customer/ user from generating station to ultimate
user the voltage get highly drop down, therefore it is
converted in to Alternating current ( AC) and then transfer
from generating station to ultimate user in distance while
the voltage get drops down we use transformers for stepping
up the voltage suitable . Therefore while transfer energy it
is High voltage ( i.e. HT ) and distributing to user this
high voltage is stepped down to suitable Low Voltage (i.e.LT
) e.g. 110v, 240v, 440v.
Differance...
HT lines LT lines
1)used for distribution
1)Use for transmitting to user.
energy from one point
to other .
2) Transformer requires to 2)no transformer require
maintainvoltage
3)Due to high voltage 3) Suitable voltage for
no user can consume energy user requirement
directly

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
