发明名称 Instantaneous fault detection circuit method and apparatus
摘要 An algorithmic system for an electronic trip unit is provided whereby reliable instantaneous protection is provided. A multi-algorithmic approach uses an algorithm to detect bolted faults based on a direct comparison of the current and a threshold value, and an additional algorithm to detect current overloads based on a comparison of a peak-to-peak current and an additional current threshold.
