Abstract

The position of the stress cone in cable termination is easy to ignore for designers. It is indicated through testing that the location of the stress cone has great impact on the overall performance of the cable termination

especially under the stress of impulse voltage. Aiming to this phenomenon

the simulation model is built by using the finite element method

and the electric field distribution for different locations of the stress cone in 110 kV cable terminal is computed. The results show that the position of the stress cone has effects on the electric field distribution of the bushing surface. It is verified by test result and the stress cone position in the bushing can not be ignored.
