Development of Combined Monitoring System of MOA Insulating Material and CT (Casing Tube) Insulating Material

Live testing of resistive current of metal oxide arrester (MOA) and on-line monitoring of capacitive current of capacitor voltage transformer or casing tube (CT) are two important parameters for stable and safe operation of power system. The present method is to separately monitor these two types of equipment. Through analyzing equipment structure, monitoring principle, integration mechanism and so on, this article realizes combined measurement of resistive current and capacitive current. Thus, the combined monitoring of metal oxide arrester (MOA), rheology and CT insulation status is achieved.
