    My own observation on above Volt drop formula am not ok with it.
    I though the formula is like this….Vd=mvA x Load (I) x Length of cable.
    But saw on the above cal the formula is like this..

    .DATA:-
    1.732 FOR THREE PHASE.
    I = 160 AMPS.
    L= 200 METERS.
    PF= 0.85

    FIRSTLY WE CALCULATE THE VOLTAGE DROP.
    Vd = 1.732 x 160 x 200 x 0.85/(70 mm2 x 41.66)
    = 16.1547 volts —————(1) for copper conductor.
    Area(mm2)b= 1.732 x 160 x 200 x 0.85/(16.1547 x 41.66)
    = 70 mm2 ———-(2) for copper conductor.

    Dear sir
    what does it means (No. of Runs of selected cable)
    thanks

    Appreciate if you could reword “Cable laying on The Depth of ” to “Cable laying at The Depth of”.
    Thanks.

    the cable resistance taken for calculation of voltage drop is having error
    reference table showing more resistance for 3C X 16 Sq.mm cable then 3C X 10 Sq.mm, copper LT XLPE

    please check

    Some people criticizing the calculations. There are many packages on the market that will calculate your cable size, volt drop etc. but at the end of the day you need to know what your doing. Even the best packages will throw up errors in calculations and if using these packages, you need to be knowledgeable to validate the output.
    This is a good tool to get you to the result you need, but you need to know what your looking at, not blame someone else for producing a tool that dumbs down what you should be competent in knowing.
