| Abstract: |
| The application of"two buses"in creepage protection is introduced.Using the commu-nication between whole protection and branch outlet protection,the insulation resistance is real-time monitored by the microcomputer of the whole protection.The faulty line can be thus quickly selec-ted out and then isolated to wholly improve the safe work conditions under well. |
| Key words: creepage protection,two buses,zero sequence current |
