Answer / ravi prakash
nowadays dual energy meters are available.let the cts be on
the common bus.connect one set of pts on each 11 kv lines
.the energy meter has got two pt refernce terminals and it
will record the kwh of each line whenever power is
available.the make of meter is CADEL.

Answer / sreejith
connect 2 cts to any 2 phases and 1 pt to one of the 11 kv
line.this will give power by 2 wattmeter method. connect
one ct to any one phase of bus and connect one pt. From
this u can get power in bus as bus will be balanced and
total power will be 3 times one phase power. If u deduct
power in one 11kv line from power in bus u can get power
from 2nd 11kv line

Answer / raman jain
As 11 kV feeder is concerned , the load is more or less
balanced . So put one PT and one CT on R-Phase of each
line , and one can measure the power on bith feeders
approximate but not exactly.
