چکیده
A power transformer is one of the most responsible and expensive assets in systems networks. Failure a can lead not only to downtime entire electricity transmission path, but also danger personnel environment. One main reasons for failure deterioration insulation windings. The windings affected by many different factors, factors effect temperature due values currents flowing through exposed effects long-term short-term loads. There are known methods tools that allow you assess technical condition under In literature, less attention paid issue influence loads, although their on thermal aging winding obvious. author has developed method mathematical model allows estimate regardless duration such an effect. essence based determination amount heat released when current flows with subsequent spread over structural elements transformer, which build distribution surface from point release. paper proposes structure device estimating residual working life basis model. article describes implementation this approach detail. It important add proposed does require significant capital investments meets requirements accuracy reliability. tool be recommended use energy companies tasks diagnosing oil transformers, integrated into monitoring system all electrical equipment plant or substation, reduce certain way costs maintenance equipment.

Characteristics of Mineral Oil-based Nanofluids for Power Transformer Application
Received Feb 7, 2017 Revised Apr 5, 2017 Accepted Apr 29, 2017 Trends in the field of nanomaterial-based transformer oil show most of the conducted works have focused only on the transformer oil-based nanofluids but limited studies on the stability of transformer oil-based nanofluids. Since mineral oil-based nanofluids still can produce the sedimentation, thus the cold-atmospheric pressure plas...
متن کاملMethod for lifetime estimation of power transformer mineral oil
Large amounts of mineral oil are used in electrical equipments as insulation and cooling medium. To avoid damages and cut-off of power electricity supply it is necessary to evaluate the mineral oil condition. Lifetime estimation of mineral oil which is based on accelerated thermal ageing at three temperatures (according to IEC 60216-1/2001) requires a long experimental time. This standardized m...
متن کاملFlexible Power Electronic Transformer for Power Flow Control Applications
This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...
