QuickField simulation example
Three phase overhead transmission line capacitance
Problem Type
Plane-parallel problem of electrostatics.
Geometry
Model length Lz = 1 km. Conductor diameter 1 cm.
Given
Phase voltage 6.3 kV.
Ground electric potential zero volt.
Solution
Transmission line of 3 conductors features self- and mutual- partial capacitances. It is convenient to use capacitance matrix calculator add-in to find all the partial capacitances.
Results
Electric field distribution around the transmission line.
