REMOTE CONTROL OF THE TECHNICAL CONDITION OF PORCELAIN HIGH VOLTAGE INSULATORS

Abstract

A survey of the technical condition of porcelain high-voltage insulators (IEE 110/400 type) was carried out at two substations of JSC «Grid Company «Kazan electric networks», using the previously developed method of two-channel remote control. Based on the measurement of a set of partial discharge characteristics (PD) and their computer analysis, the technical condition of 38 PVIs was diagnosed with the division into four groups; Fully operational; Workable at the given time; Limited working capacity and requiring replacement during subsequent routine inspections; Completely inoperative, requiring immediate replacement.
