Load calculations

hi,

The arrangement of the KWH in each phase is 3 phase 4 wire system and the loads are connected in a WYE connection...

Can you also give me an idea on what the values are if the loads are connected in a Delta connection..

Thanks very much and more power...

From what you indicate in your question, the connection is Y (star,Wye).

In this case the current for each phase is basically Pphase/Uphase, where Pphase is the (active) power indicated for that phase while Uphase is the phase-to-neutral voltage for that phase. That voltage, since nothing contrary has been indicated, is equal for all 3 phases. You indicated there 240/380 V. This is not OK since in a Y connection the phase-to-phase voltage is phase-to-neutral * sqrt(3), which in your case is not.

So either you use 240/416V or 220/380V.

In your case:

phase R: IR = 24200W/240V = 100.83A

phase Y: IY = 24300W/240V = 101.25A

phase B : IB = 24732W/240V = 103.05A

when using 240V as phase-to-neutral voltage.

Since all power you indicated are active power (kW), and not any specific value for measured voltages on the 3 phases, you do not have any information that could allow you to calculate reactive power, apparent power, etc.

For Diversity factor and demand factor you need additional data refering to the number of loads, how their power varies over a certain period of time, etc
