Three phase cable

Cable leakage current, underground cable simulation, 3 phase cable, three phase cable

This is an example of the 3-phase cable simulation, performed with QuickField software.

Problem Type
Plane-parallel problem of AC conduction.

Geometry
Three phase cable High frequency (400 Hz) three phase cable leakage current calculation phase A phase B phase C Ground Shield Insulation

Cable diameter 80 mm, insulation thickness 5 mm, shield thickness 5 mm.

Given
The cable consists of 4 isolated conductors and is buried in the ground.
Voltage U = 250 V.
Frequency f = 400 Hz.

Task
Determine the leakage current.

Result:
Electric field stress distribution in 3-phase cable:
electric field stress in the cable insulation
