This is an example of the 3-phase cable simulation, performed with QuickField software.
Plane problem of AC conduction.
Cable diameter 80 mm, insultion thickness 5 mm, shield thickness 5 mm.
The cable consists of 4 isolated conductors and is buried in the ground.
Voltage U = 250 V.
Frequency f = 400 Hz.
Determine the leakage current.
