Line loss means power loss occuring during transmission of
Electric power. It is mainly due to copper loss(I2R). The
best way to reduce this is by increasing the voltage by
using a step up transformer, because when stepping up the
voltage, current decreases proportionatily. when I
decreases, I2 also will. Thus altogether I2R will decrease.

Answer / sk sazzadur rahaman

Line loss means loss due to I2R effect. That is the heating
loss in the transmission line. It is equal to Current
square multiply by resistance of total line.
It can be reduced by reducing the resistance of the line
ie. by increasing the diameter of wire. Or by sending the
same wattage, reduce current and proportionally increase
the voltage.

Answer / ram t shelke

line losses can be divided as 1) copper losses 2) reactive
power loss 3) corona loss. copper loss mostly depends on
current flowing through the line & resistance of the
conductor.so try to keep these two values to minimum by
increasing system voltage& selecting proper size conductor.
reactive losses can be reduced by managing line loading
nearer to SIL conditions.the corona loss can be reduced by
increasing conductor size or using hallow size conductors.

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
