My company is operating on a 3phase 4 wire systems
ie(415v b/w phases, 240v between phase and neutral wire).
1 have the following load calculation to make
(A)SINGLE PHASE LOADS
(1)flourescent fitings 40W 240v 100 units
(2)electric motor 1kw 240v 30 units
(3)air conditinal 2kw 240v 10 units
(B)3PHASE LOADS
(1)water pump 4kw 415v 6 units
(2)5tonnes airconditioners 12kw 415v 10 units
(3)packaging m/cs 4kw 415v 100units
what I did was to add all the KW of the single phase loads(A)which gave 54KW and divide the value by 3 to get the 3phase Equivalent of the single phase loads.(54/3=18KW)
this was then added to the total kws of the 3phase loads.
which gave=18kw +544kw
=562kw
as the combined load rating for the factory
can someone out there confirm if this calculation is correct.
also,I would like to know the size of generator that would be adequate to supply power to this loads.
