基于赫斯特指数的车辆48V系统高阻抗直流电弧故障检测

Expanding dc electrical distribution systems require improved detection and mitigation of dc arc events. The high heat resulting from dc arcing raises concerns on equipment and personnel safety. In this article, a new adaptive detection method for series dc arc faults is presented. The proposed detection method utilizes Hurst exponent estimation of the system current to detect arcing events with a...
