| Abstract: | The principle of duplicate-busbar differential protection is introduced. Some problems on duplicate-busbar differential protection in commissioning and operation process are analyzed and researched. The effect of busbar switch＇s position on the sensitivity of microprocessor-based busbar protection device as well as the effect of base transformation ratio on the line breaking of current transformer is elaborated. Some solutions and recommendations are presented accordingly to ensure the normal operation of relay protection device. |
| Keywords: | busbar differential protection switch position operation and maintenance |
