| Abstract: | Continuing cold weather of freezing rain and snow causes ice accretion on overhead transmission lines,which brings serious harm to power grids.Icing online monitoring is of great significance.The principles and functions of online icing monitoring system were introduced. In the monitoring program,the icing process is divided into four stages which are formation,steady growth,slow growth and disappearance. The summarization of system development and operation indicates problems existing in tension sensors an... |
