| Abstract: |
| The effect of isolator operation on the selectivity of medium impedance and digital bus bar protections is analyzed. It is pointed out that, if bus bar fault occurs during the open or close operation of isolator, the fault zone may expand and the hazard to personnel may happen.Some suggestions and concepts are proposed. |
| Key words: isolator,bus bar protection,operation mode, |
