MAGNETIC INRUSH CURRENT OF TRANSFORMER REDUCE BY POINT WAVE SWITCHING METHOD
Keywords:Transformer current, magnetic inrush current
At the time of transformer energization, a high current will be drawn by the transformer. This current is mentioned transient inrush current and it may rise to ten times the nominal full load current of transformer during operation .This current can produce mechanical stress to the transformer, causes protection system malfunction and it often affect the power system quality and may disrupt the operation of sensitive electrical loads such as computers and medical equipment connected to the system. Energization transients current reduce by use of point on wave switching at the time transformer is initially connected to supply. In this paper the simulations and the experimental results on a three-phase transformer for reduction of inrush currents. An electronic devices three-phase switching controller has been designed and some thyristors are used for switching power to the transformers. Reduction of magnetic inrush current and the way to control of energization transients currents have become important concerns to the power industry for engineers.
