Dear All,
I want to calculate voltage drop in the cables used for lighting (industrial) purpose. Please let me know if there is any formula available to calculate the Voltage Drop.

Thanking You.

    This is online voltage drop calculator
    fill in the details & get the result 😉

    and <a href="https://www.nooutage.com/vdrop.htm" target="_blank" rel="nofollow noopener noreferrer">Voltage Drop Calculator - for single and 3 phase ac systems and dc systems</a>

    for more details : #-Link-Snipped-#

    Manually,
    Single phase voltage drop:
    Vd= 2K x L x I / Cm

    Three phase Voltage drop:
    Vd=1.73K x L x I / Cm

    Where,
    Vd = voltage drop
    K = 12.9 for resistance of copper conductor
    L = Length of circuit in feet
    I = current or amps. of load
    Cm = Area of conductor in circular mills
