Single phase-to-ground fault - Open Access .click

Electrical Engineering, 1942
In the application of differential relays the need for a supervising relay which will detect the existence of a single-phase-to-ground fault condition to the exclusion of all others has frequently arisen. Heretofore, the only scheme available has been to utilize a relay energized by zero-sequence quantities. Generally, the relay has been energized by a

Estimating locations of single-phase-to-ground faults of ungrounded distribution systems

IEEE PES ISGT Europe 2013, 2013
This paper proposes a new method for determining single-phase-to-ground fault locations of ungrounded distribution systems based on the measurements collected from the feeder breakers and intelligent switches during the fault. The method first narrows down the possible faulted area into a specific feeder section based on the reactive power factors of ...

Study on Fault Location of Single-Phase-to-Ground for Distribution Network

Advanced Materials Research, 2012
The AC-DC method (the AC method combined with the DC method) has integrated the superiority of the AC method’s easy measurement and the DC method’s reliability, so it has achieved some degree of use. The method before only took the ground resistor as the condition of combination, so it is not perfect.
