| dc.description.abstract-translated | This paper introduces a methodology to investigate controlled switching (or "Point on Wave Switching") to reduce magnetizing inrush current in Transformer. When transformer is switched on, transformer will get energized and transiently, large current flows through the primary winding. This mentioned current is - transient inrush current and it may raise up to ten times (or more) the nominal current of transformer during operation. Though transient inrush current lasts within few cycles, it has some bad effects e.g. problems with operations of protective devices, production of mechanical stress to the transformer core, power system quality, problems with sensitive electrical loads such as medical equipment and computers connected to the grid. Hence decreasing of transient inrush currents is important. The method using controlled switching means connect transformer at the correct phase voltage waveform to achieve the minimum inrush current. This reliable method was chosen to prevent generation of high magnitude inrush current. The non expensive electronic system for inrush current decreasing for single phase transformer switching on was developed and successfully tested in practical use. | en |
