power cable voltage drop FAQ: What is voltage drop , Eland Cables

A voltage drop in an electrical circuit normally occurs when a current passes through the cable. It is related to the resistance or impedance to current flow with passive elements in the circuits including cables, contacts and connectors affecting the level of voltage drop. The longer the circuit or length of cable the greater the voltage loss.

· Example 1: Determine voltage drop Run a No. 10 stranded wire 200 ft at 20A. Per Table 9, our "ohms to neutral per 1,000 ft" is 1.1 ohms. . If you have non-linear loads, use the column that helps account for power factor. Equation 1: Calculating the actual Voltage Drop in volts Volts Dropped = (2 x 0.866) x L x R x Amps/1000.

· Here voltage drop for 70 Sq.mm Cable (5.8 %) is higher than define voltage drop (5%) so either select higher size of cable or increase no of cable runs. If we select 2 runs, than voltage drop is 2.8% which is within limit (5%) but to use 2 runs of cable of 70 Sq.mm cable is not economical, so it’s necessary to use next higher size of cable.
