Sensitive ground-fault relaying

IEEE Transactions on Industry Applications, 1988
Sensitive ground-fault protection refers to the concept of detecting low levels of ground-fault current that might cause electrocution of any human that becomes part of the ground-current path and providing warnings. The concepts behind sensitive ground-fault relaying for use on AC and DC low-voltage utilization systems are covered.

Cascade ground fault investigation

Proceedings of IEEE Pulp and Paper Industry Conference, 2002
The occurrence of multiple ground fault events in a low resistance grounded 13.8 kV power system may have an unexpected cause. This situation serves to illustrate that short circuit and load flow analyses alone are becoming increasingly inadequate as the sole means used to insure proper system operation and to minimize disruptions in three phase power ...

Improved Scheme for Single-Ground Fault Suppression Based on Grounded-Fault Transfer Device

2020 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2020
For the sake of reliability of power distribution, medium voltage distribution networks apply small-current earthed mostly. However, traditional resonant earthed methods applied arc suppression coil have poor performance as capacitive current growing rapidly.

Directional ground fault indicator for high-resistance grounded systems

IEEE Technical Conference Industrial and Commerical Power Systems, 2003
Locating ground faults is a difficult and challenging problem for low-voltage power systems that are ungrounded or have high-impedance grounding. Recent work in pilot signals has renewed efforts in developing fault location methodologies. This paper presents a method for directional ground-fault indication that utilizes the fundamental frequency ...

Fault-resistance effect on ground fault current

Electrical Engineering, 1953
GROUND FAULT currents may be reduced substantially when fault resistance is included in the fault circuit. The majority of faults that occur on a power system involve ground and occur between conductor and tower. When a fault occurs to a steel tower or grounded wood pole on a grounded system the footing resistance is included automatically in the fault

Power system faults to ground: Part II: Fault resistance

Electrical Engineering, 1937
AN ALLOWANCE for fault resistance in fault current computations is desirable in certain types of problems. The present paper gives the results of a study made to determine reasonable values of fault resistance to use in computing line-to-ground fault currents, particularly in inductive co-ordination studies.

Improved Generator Ground Fault Schemes

2020
The purpose of this paper is to review new or improved methods related to generator ground fault protection. Established stator ground fault protection schemes as referenced in IEEE Guides C37.101-2006 and C37.102-2006 are proven to be effective under the most common failure modes but may fall short in detecting faults that develop due to arcing faults

Performance of Ground-Relayed Distribution Circuits During Faults to Ground

Transactions of the American Institute of Electrical Engineers, 1942
An extensive oscillographic study has been made on power distribution feeders primarily to obtain data useful in the consideration of joint use of poles by power and telephone facilities. Some of the results, chiefly those obtained from three-phase, four-wire, multigrounded neutral feeders equipped with instantaneous ground relays and for immediate ...
