Manufacture and Performance Evaluation of Insulating Transformer for surge protection under Electric Railway Environments

전기철도환경하에서의 서지방호용 절연변압기 제작 및 성능평가

The main aim of the paper is the study of the surge voltages in electric railway signal security system. Hence these studies will provide means of introducing a suitable protective device insulating transformer. This influences the surge voltage interrupting capacity using surge arresters and bypass capacitors. This circuit can be used for investigating surge phenomenon in electric railway signal security system. In this paper a insulating transformer has been introduced for the reduction of surge voltages in the above circuit model and performance evaluation.
