Short circuit current (PSCC)
for mono-phase systems.

Mono-phase or DC system

Calculates the short circuit current also called fault current or prospective short circuit current (PSCC) of a mono-phase or DC line, PSCC and maximum current values are essential for choosing the right protection.

Data input

Selection of conductor material

Specific resistance

Wait value

ohm/mm2 m

Voltage of the circuit

V

Wire section

mm2

Line length

m

Same section for the two wires

(AC and DC lines)

Section of the neutral wire halved

(only AC lines)

Wait calculate
Results
