The article deals with the condition estimation of 6-10 kV cable lines (CL) with impregnated paper insulation (IPI) taking into account their length and operational reliability measures according to failure statistics. The subject under study is urgent because of the lack of reasonable insulation diagnostics of CL. The article theoretically justifies the CL diagnostics with non-destructive methods...
The article deals with determining of periodicity of non-destructive examination of urban electric cable lines. As a criterion to select the periodicity of examination of cable lines a complex reliability indicator, technical readiness coefficient Ktesrf is applied which takes into account self-repairing failures. This coefficient gives the most profound description of the current state of the cable...
