双探头电容传感器用于非传导式交流电压测量的研究

Dual capacitive sensors for non-contact AC voltage measurement

讨论一种新型双探头的电容传感器用于交流电压的精确测量.用正交最小二乘估计来确定两个探头所得数据和所测电压的关系,误差可降到5%左右.

In this paper, a capacitive probe with two sensor heads has sensing of AC voltage. It is able to extract the relationship between the two voltage and the fitted model is able to reduce the estimation error to around been developed for the accurate induced currents and the supply 5%.
