The Design Based on Integrated Criterion to Faulty Line Selection for Small Current Neutral Grounding System

Abstract:

Small current neutral grounding system is widely used in 3~66 kV power distribution system in China. In this power system, the single-phase to-earth fault occurs frequently in distribution, thus how to detect the fault line with great accuracy and high efficiency is an important subject in protective relaying of power system. According to a variety of existing theories of fault line selection for small-current neutral grounding system, this paper presents a new design based on integrated criterion, which has been applied in actual production.
