Step 1 : Find the Cable Resistance and Reactance

Referencing standard 'AS/NZS 3008.1.1.2017' for a {{calcvals.MimsVoltage}} {{calcvals.CableType}} {{calcvals.CableFormation}}, three phase cable with {{calcvals.CableInsulation}} insulation and {{calcvals.CableFormation == "Multicore" ? calcvals.MulticoreArrangement : ""}} {{calcvals.Metal}} conductors laid in {{calcvals.SinglecoreArrangement}} at an operating temberature of {{calcvals.MimsTemp}}{{calcvals.CuTemp}}{{calcvals.AlTemp}}℃, the resistance and reactance for a cable with {{calcvals.conductor}}mm² size conductors is:

Result : Review the Voltage Drop

The computed voltage drop equates to {{ calcvals.voltagedroppercent }} % of the supply voltage, which is greater than the maximum permissable voltage drop.

The computed voltage drop equates to {{ calcvals.voltagedroppercent }} % of the supply voltage, this is less than the maximum permissable voltage drop.
