高阻抗故障伴随着60 Hz和谐波分量的变化。一种方法，占的基本和谐波分量的时变性质的开发。这种方法是基于卡尔曼滤波理论，以获得最佳的估计的基波和谐波分量的时间变化。四个实际记录的数据集，不同类型的土壤上的阶段性电弧故障的建议卡尔曼滤波技术进行了研究。基波和低次谐波分量的时间变化显着有助于高阻抗故障检测使用的功能。>
High-impedance faults are accompanied by variations in the 60 Hz and harmonic components. An approach that accounts for the time-varying nature of the fundamental and harmonic components is developed. This approach is based on Kalman-filtering theory to obtain the best estimation of the time variations of the fundamental and harmonic components. Four actual recorded data sets for staged arcing fault on different types of soil are investigated by the proposed Kalman-filtering technique. The time variations of fundamental and low-order harmonic components significantly contribute to high-impedance fault detection using the features presented. >
