Development new measurement method for current collection quailty using track-side monitoring system

초록

To achieve speed up of high speed trains in the field of catenary systems, it is necessary to develop new analysis methods for current collection performance between pantograph and OCS. Currently the most dominant methods to assess performance of current collection systems are on-board monitoring systems such as photo sensor based systems or contact force based systems. However, these methods are only capable of measuring on the train which are installed measurement systems. Therefore in this paper, a track-side monitoring system was implemented to measure electrical characteristics from active overhead contact wire systems in order to constantly estimate current collection performance of railway operation. In addition, a method to analyze loss of contact phenomena was proposed.
