| Abstract: | The comparisons between optical fiber phase-splitting current differential protection and optical fiber pilot zero sequence protection in terms of their principles and requirements on protection channel lead to the conclusion that under the premise of channel conditions,the choice of two sets optical fiber phase-splitting current differential protection should be given priority to for the duplicate protection of 220kV line. |
