A new single-phase-to-ground fault-detecting relay

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.

A survey on faulty line selection technology for single-phase-to-ground fault in China

2013 IEEE Industry Applications Society Annual Meeting, 2013
Single-phase-to-ground fault is difficult to detect with traditional methods in NIEPS because of minor fault current, fault arc, harmonics influence and the protection principle limitation. In order to improve the precision and reliability of traditional faulty line selection technologies for NIEPS, more attention has been paid by many researchers over

Modeling and simulation analysis of single phase arc grounding fault based on MATLAB

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
The single phase arc grounding fault is a main fault form in medium voltage distribution networks. It is essential to build an accurate grounding arc model for fault analysis. In this paper, a new grounding arc model is built based on the MATLAB with the arc gap energy-balance theory.
