Abstract

A Sensor to measure electric vector fields based on the Pockel effect and a sensor making good use of a search capacitor have been submitted to the same electric field excitations. Outputs of their analog electronics are further processed using a multi-channel dynamic signal analyzer (24 bits and 10 mHz to 100 kHz analysis bandwidth). Both AC and DC behavior have been addressed, the later with the help of an electric field mill. The direct comparison was made possible up to 100 kVm−1 using a large enough electric field source and high voltage outputs amplifiers. This way, the sensors are operated at the same time, while occupying similar positions inside the electric field. Results expressed as a voltage transfer function in the AC mode exhibit a good coherence all along the analysis band. It highlights the different bandwidth of the two instruments nonetheless sharing three decades: the search capacitor working at low frequency while the electro-optic one is known to work at high frequency. Finally, the electric field mill used at a chopping frequency of 54 Hz induces a limitation for both sensors in the lower part of their measuring range, below a few hundreds of Vm−1, while noise floors of each sensor are found well below a residual signal induced by the electric field mill rotation.

电容式和光电式电场传感器的直接比较
在相同的电场激励下,提出了一种基于波克尔效应的矢量场传感器和一种利用搜索电容的传感器。其模拟电子输出使用多通道动态信号分析仪(24位和10 mHz至100 kHz分析带宽)进一步处理。交流和直流行为都得到了解决,后者是在电场磨的帮助下进行的。使用足够大的电场源和高压输出放大器,可以在高达100 kVm−1的情况下进行直接比较。这样,传感器同时工作,同时占据电场内相似的位置。在交流模式下用电压传递函数表示的结果在整个分析带中表现出良好的相干性。它强调了两种仪器的不同带宽,尽管它们共享三十年:搜索电容器工作在低频,而已知电光电容器工作在高频。最后,在54 Hz斩波频率下使用的电场磨对两个传感器的测量范围都有限制,低于几百Vm−1,而每个传感器的本底噪声都远低于电场磨旋转引起的残余信号。
