| Abstract: | This article is based on 500 kV protection application principle of East China Grid.It analyzes and compares 500 kV breaker failure protection by foreign and domestic manufacturers.From the way they achieve lockout single phase re-trip,prepare three phase trip and auto re-closing,it summarizes their merits and defects,gives some suggestion for improvement.Finally,it describes some concepts,which maybe conducive to better understanding. |
