Experimental investigation and modelling of thermal transients of underground high voltage cables

Smith F. ; Holtzhausen J.P. (1994)


This paper describes a laboratory investigation into the transient heating of underground XLPE cables and a computer simulation of the laboratory set-up. Rather than using analytical methods, it was decided to use a transient circuit analysis program, using a ladder network electrical circuit analogue of the transient heat flow problem. The simulation was done, using the electromagnetic transients program, EMTP. Results of reasonable accuracy were obtained, but a major problem appears to be to identify suitable parameters for the laboratory set-up.
