Answer / gurucharan singh

Actually, there are various stages for transmission. Like
from generation to power transfro. & transm. line upto step
down transfro. its gerenally 20 to 25 kms length is about
3.5% to 6% of losses of actual power to be transmitted
depends up on design of line.
Then for inter-state & state internal losses for power are
different. this total sum can be in range of 12% to 16% of
power transmitted.

Answer / pravin kumar sharma

my brother are saying right in above ans.. but not fully right...just first u have to take one by one phase asume for R phase... as per length just u calculate its resistance..which is alerady decided by per km for any type of conductor...like..panthar , zebra as so onnn///and after that find how many electrical power will be delevered for in same circuit...... now its very easy....losses in single phase = IxIxR..............where for I u have to just devide power / potential votage of transmission lines.....................

Why does the phase voltage of two healthy phases become equal to the line voltage in case of an ungrounded neutral 3 phase star connected sytem when a single line to ground fault occurs ?

1.Whats the use of GNAC(Generator Neutral Accessory Compartment) 2. why generator or any other system require Neutral Grounding and not Phase grounding 3. what happens if any one of the phase is grounded. 4. if 15kv is grounded directly what will happen, why it should not be grounded like that 5. use of of NGTR(Neutral Grounding Transformer and Resistor) for grounding is helpfull and how

My switchgear busbar is rated at 2000A and just imagine the actual load on busbar is 1000A. From that busbar there are 10 outgoing feeders. Now the question is will the load be 1000A on each outgoing feeder or 100A per outgoing feeder. 2nd thing how do i calculate the load on individual feeder. Thanks for your time. Please provide some clarification on this issue.
