Transformer fault diagnosis and repair is a complex task that includes many possible types of faults and demands special trained personnel. In this paper, Petri Nets are used for the simulation of transformer fault diagnosis process and the definition of the actions followed to repair the transformer. An integrated safety detector relay is used for transformer fault detection. Simulation result...

According to the chronological literature survey, there exist three types of the on-chip transformer i.e the traditional on-chip passive transformer, the Distributed active transformer (DAT), and the CMOS gyrator-C active transformer (Yuan 2007). Formerly, there exist many review articles on the on-chip transformer. However, these articles focus on the on-chip passive transformer due to its ren...

Transformer is the power equipment of power system core. Intelligent monitoring and operation of transformer can not only monitor the full range of the transformer, the realization of state evaluation, it should be required repair, maintenance required good, but also on the latent fault early diagnosis and prediction. Research on transformer intelligent monitoring and operating technology of sa...

A contactless power transfer system for charging electric vehicles requires a high efficiency, a large air gap, and a good tolerance to lateral misalignment and needs to be compact and lightweight. A double-sided winding 10 kW transformer based on a 1.5 kW H-shaped core transformer was developed for a rapid charger. Even though the transformer capacity was increased, the dimensions of the 10 kW...

Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) 15 (16.7 traction systems do not have the characteristics behaviour of a typical three-phase medium-voltage distribution system. Switching inductive loads vacuum circuit breaker (VCB) in MV poses familiar challenges as well some unique challenges, such crossing phase change neutral sections. Transformers represent hig...

The paper deals with the issues of energy saving in railway section, which has a tunnel double longitudinal slope, limits capacity trains due to decrease rated voltage by more than 10%, negatively affects thermal and transient electromechanical processes. practicality regulation using existing installation series compensation is shown; it proposed use an additional parallel reactive power compe...

Power quality and neutral section are two technical problems that hinder the development of electrified railway to high-speed heavy railway. The co-phase power supply technology is one best ways solve these problems. At present, a V type connection traction transformer widely used in frequency single-phase AC system, especially In this paper, new system for based on proposed. One winding as mai...

Using image processing technology has become increasingly essential in the education sector, with universities and educational institutions exploring innovative ways to enhance their teaching techniques provide a better learning experience for students. Vision transformer-based models have been highly successful various domains of artificial intelligence, including natural language computer vis...

in working process of power transformer, which directly affects the safe operation of transformer oil temperature as well as the stability of the network, so vital to transformer oil temperature detection and control. Based on single chip and chip design of digital temperature measurement transformer oil temperature of an intelligent control system. The system uses a digital temperature sensor ...
