Performance of nonlinear grading coating on polymeric outdoor insulators under lightning impulse voltages
This paper investigates the performance of an 11kV polymeric outdoor insulator equipped with a nonlinear grading material when subjected to a lightning impulse voltage. The grading layer is introduced as a field dependent material at the interface between the core and the silicone housing....

| description | This paper investigates the performance of an 11kV
polymeric outdoor insulator equipped with a nonlinear
grading material when subjected to a lightning impulse
voltage. The grading layer is introduced as a field
dependent material at the interface between the core and
the silicone housing. The equipotential contours and
electric field distribution over the insulator surface were
computed and analysed using the Finite Element Method
(FEM). Comparative studies show that the nonlinear
grading layer, with an appropriate electrical property, can
be an effective approach to reduce the electrical stress
along the insulator by redistributing the surface field into a
more uniform distribution. |
