you are measure the one conductor size 35 sqmm cable in
micro meter than you give a size in squre and multiple by
pae multiple by number of conductor dividing by number of
core,you are give the any cable size.
for example. i measure the 4 core * 300 sqmm cable size
(2.5)squre x pae x 61 /dividing by number of core 4
Cable size (area of each core) is normally specified in square millimeters
(sq. mm). In this case it is 35 sq. mm. The cable size is always printed / marked on the cable itself by the manufacturer.
The conductor in each core of power cables is normally made of multi strand circular wires (Copper / Aluminum ).
To measure the size/area of the conductor, measure the diameter of a strand in a core and calculate its area. Multiply this area by number of strands in a core.
If the diameter of a strand in mm is D,
then its Area = [∏/4] [ DxD ] = [3.14/4 ] [DxD] Sq. mm.
Size of the cable (or) Cross sectional Area of a Core
= [Area of a strand x No. of strands in the core].
what is the HT motor current setting (Motor protection
relay)aganist FLA If the capacitor is connected in parallal
to the motor to increase the P.F from 0.89 to 0.99.
the setting is to be reduced. what is the formula for to
calculate the current.(FLA - CALCULATED CURRENT!= )
