Abstract

This paper addresses some shortcomings of existing IEC standards related to analyses of cable systems with polymer insulation (IEC 60840 and IEC 62067). The focus is on partial discharges measurement, completely neglected in present version of these standards, and justification of the needs for their inclusion in the standards through appropriate procedures. If included in the standards the procedures would provide an effective way to identify and detect the defects that might appear during the cable system installation and to forestall their appearance during exploitation. The simulation evidences, to suggest and justify the changes in the standards, through a modelling of partial discharge phenomena using contemporary software tool (COMSOL) are provided in this paper.
