how can u determine size of the conductor by knowing the
voltage level
Answer Posted / naveen
Yes one could determine the size of the conductor by knowing
the voltage levels and some other factors too.Also the
maximum voltage that can safely be applied to any winding is
determined by the type and thickness of the insulation used.
When a better (and thicker) insulation is used between the
windings, a higher maximum voltage can be applied to the
windings.
To be more specific by equations,
VD= 2*K*I*L/ CSA
WHERE:
VD= VOLTAGE DROP
I= CURRENT
L= DISTANCE OF THE LOAD FROM THE OUTLET (IN FT)
K= 12 FOR COPPER AND 19 ALUMINUM (FOR MAXIMUM TEMP OF 75 DC)
CSA= CONDUCTOR CROSS SECTIONAL AREA IN CIRCULAR MILS.
