Digital twin technology as an instrument for increasing electrical equipment reliability

The article describes the experience of practical realisation of digital twin technology for voltage and current measurement transformer 110 kV installed in real power station. In terms of the research electrical equipment state monitoring system has been developed as a set of sensors and diagnostic system, based on essentially different approaches of non-defective diagnostics. 3D model construction of the equipment under monitoring is also described as a part of digital twin concept. It is shown the valuable impact of digital twin technology application. © Published under licence by IOP Publishing Ltd.Russian Science Foundation, RSF: 18-79-00201The reported study was supported by Russian Science Foundation, research project No. 18-79-00201
