摘　　要：监测海底装备接地故障需要精确测量其供电线路的接地电阻值。区别于以往固定式采样电阻的检测方法,文章设计了切换式采样电阻阵列的新方法进行信号采样,并应用加权平均法对数据进行信息融合。试验数据表明,该方法有效地提高了测量精度和准确度。Fault ground resistor value should be measured accurately to monitor this fault in underwater equipments. Traditional method is measuring the voltage on the two ends of the sampling resistor with invariable value. Due to the extremely wide range of the resistor value, this measure can＇t assure the accuracy. The paper proposes a new method of using switchable sampling resistors and processing data by weighted fusion algorithm. The test result proved that this new method improves the measure accuracy.
