To avoid failures in the insulation the measurement of the dielectric losses could be a helpful tool. RCIICR ?? 1tan ??VLF Tan Delta Tan Delta basics U IC IR I δ Dielectric losses are mainly dominated by the conductive losses that occur in the insulation material, in case of papermass cables also the polarizationlosses will influence the dielectric losses. The Dielectric losses (Tan Delta) can be calculated according to : Visually given by: In simple terms, the insulation resistance is inversely proportional with the Tan Delta.

VLF Tan Delta Tan Delta basics The most important ageing phenomenon for PILC cables is the degradation of cellulose, what basically means that moisture es free from the paper insulation because of thermal and chemical processes. This moisture content will decrease the insulation resistance, resulting in an increase in Tan Delta. It is clear that with PILC cables external water ingress will also influence。F ?Test capacity 0,01Hz: 5,0181。F 60 kV 7,0 181。F 60 kV 10,3 181。F 54 kV 8,0 181。fZusatz (test add on) CEN Centrix OFFS Offshore (grouted HV output line) (c) SebaKMT, all rights reserved Products VLF CR technology – Portable solutions II VLF CR40P (899004501) VLF CR40PPZCEN (890022741) 4,4 181。F 18 kV 181。C , n o n c o n d e n s in g )D i m e n s i o n s 5 0 0 x 4 5
