Signal cable EMC
QuickField simulation example
Power and signal cable are buried in a common duct. Calculate the electric field distribution and find the mutual capacitance.
Problem Type
Plane-parallel problem of Electrostatics.
Geometry
Given
The power cable consists of 4 isolated conductors A, B, C, 0.
Voltage U = 660 V, frequency f = 50 Hz.
The signal cable consists of 4 isolated conductors s1, s2, s3, s4.
Task
Determine the mutual capacitance.
Solution
To calculate self and mutual capacitances of conductors the Capacitance calculator addin is used.
