Synopsis

An adjoint sensitivity analysis of a nonlinear transient finite-element model allows to determine the sensitivities of the key performance indicators of a cable joint with respect to the parameters of an embedded field-grading material. The example considers a high-voltage DC cable joint submitted to an overvoltage event.
