QuickField simulation example
Disc insulators are connected in chain of two. The insulators are suspended from the grounded tower arm and carry HV power line conductor.
Problem Type electrostatics.
Geometry 3D import.
Relative permittivity of the insulator (glass) εr = 5,
Transmission line potential V = 10 kV (RMS, line to line voltage).
Ground voltage = 0 V.
Calculate the electric field stress distribution on insulators surface.
Line voltage is measured between the phase conductors. The phase voltage (between phase conductor and ground) is √3 times smaller than the line voltage.
We should specify the peak voltage value (*√2).
