Supply Details

Line Voltage

Enter the 3 phase supply voltage. The phase to earth voltage will be calculated automatically from the supply voltage and number of phases

Supply Rating (kVA)

Maximum Total Volt Drop

Fault Current

Enter the prospective fault current for the supply.

A default value of 6kA is used but it is suggested that you contact your local supply authority for this value.

Impedance, Power Factor, Resistance & Reactance

It is suggested that you only enter these figures if they have been supplied via your supply authority.

Phase Earth Voltage

The phase to earth voltage is calculated automatically from the supply voltage and number of phases
