| Abstract: | Because the value of the resistance components can be set independently, a quadrilateral-characteristic distance relay is very sensitive to a large earthed resistance when faults.In view of that,the relation between the load impedance and the quadrilateral characteristics of a distance relay in R-X plane is analyzed in detail.And also,the method to reliability coefficient calculation is put forward. |
