How to calculate 3 phase voltage drop

WebTo calculate the voltage drop for a circuit as a percentage, multiply the current (amps) by the cable length (metres); then divide this number by the value in the table. For example, a 30m run of 6mm2 cable carrying 3 phase 32A will result in 1.5% drop: 32A x 30m = 960Am / 615 = 1.5%. AS3000 Table C7 Example Web20 nov. 2024 · Volt drop = Y x current x length = 1.1 x 100 x 150 millivolts = 1.1 x 100 x 150 volts/1000 = 16.5 volts where Y = value from tables in mV/A/m Unless a particular value of voltage drop, acceptable to the user, is specified, the IEE Regulations figure of 10.5 volts must be adhered to. Thus: total volt drop = 10.5 volts 10.5 = Y x 100 x 150
