IN 3PH. NEUTRAL CARRIES ONLY UNBALANCE CURRENT MEANS IF ALL
PHASE ARE CARRYING SAME FOR EXAMPLE 20AMPS THEN CURRENT IN
NEUTRAL WILL BE ALMOST ZERO AMPS.

Answer / saireen

3.5 c cable neutral is not the return path for the face but only that current which r unbalance among 3 phase, and that is sufficient to keep size 1\2 as compare to phase.

Our Alternator nameplate specifies a power factor of 0.8. When the Alternator is on light load, the bus bar voltage rises to 11240 volts, whereas the standard value is 10500 volts. Is it ok to increase the power factor to 0.85 or 0.9. I am afraid because the power factor on the name plate is only 0.8 ?
