This is an example of the cable termination simulation, performed with QuickField software.
Axisymmetric problem of transient electric.
Relative permittivity of air ε = 1.
Relative permittivity of insulation ε = 2.
Relative permittivity of shield ε = 1.2.
Relative permittivity of stress control tube - nonlinear.
Central conductor potential V = +4 kV.
Screen potential - 0 V (grounded).
Calculate the effect of electric stress reduction.
With stress control tube the maximal electric stress reduces from 1.6 to 0.5 kV/mm.
