DEVICE FOR ASSESSMENT OF POWER TRANSFORMER TECHNICAL CONDITION

摘要

FIELD: electricity.;SUBSTANCE: device comprises measurement devices, memory devices and also information processing and display devices. Its principle of operation is based on dependence of spent resource of transformer on value of consumed current and ambient temperature. Device makes it possible to control technical condition of transformer by realisation of continuous calculation of spent resource of transformer, to timely make decisions to perform this or that type of maintenance, and what's more important, to track the moment, when the equipment should be decommissioned and sent for repair, thus, preventing accidents.;EFFECT: expansion of functional capabilities due to automated accounting of factors that reduce the resource, calculation of spent resource and making decision on prospects of further functioning of power transformer.;1 dwg
