Protection method of small current grounding system based on phase current variation
2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2), 2020The probability of single-phase earthing fault is very high in indirectly grounding power system, so it is very important to select and trip the fault line quickly. According to the theoretical analysis, the difference between the faulty phase current’s variation and the non faulty current’s variation of the faulty feeder is significantly larger than ...

Resonance Analysis of Small Current Grounding System in Distribution Network
2018 China International Conference on Electricity Distribution (CICED), 2018At present, there are a large number of arc suppression coil grounding mode in the low-voltage distribution network for the equipment insulation and power supply reliability considerations. The role of arc suppression coil grounding mode is when the grid single-phase ground fault occurs, arc suppression coil will provide inductor current to compensate ...

Research on Ferroresonance Detection in Small Current Neutral Grounding System
Advanced Materials Research, 2013A novel method to detect ferroresonance was proposed based on the drastic characteristics of the electromagnetic voltage transformer (PT) current rate. This scheme takes current rate which is greater than a threshold value as starting signal and judges the occurrence of resonance by detecting duty ratio of the peaks and interval angles.

Automatic fault line selection technology for small current grounding system
2017 2nd International Conference on Power and Renewable Energy (ICPRE), 2017The low voltage distribution network in our country widely adopts non-direct grounding system, called as small current grounding system. Single-phase ground fault is the most common occurrence for this system. Now, some power supply departments in our country still recognize fault lines by traditional artificial method, meaning low efficiency and ...
