电场探头支架对工频电场强度的影响

摘要

采用两种不同型号的工频电场监测设备进行现场监测时，发现测量数据存在较大的偏差；为研究产生偏差的原因，对这两种设备进行了比对实验。结果表明：工频电场探头的支架所用材料是影响工频电场测量的一个重要因素，支架上存在金属部件会对工频电场的测试结果产生较大影响。%It is found that there is large deviation between the data from two types of monitoring devices for power frequency electric field intensity measurement, and for analyzing the deviation, comparison experiments are carried out. The results show that the material for the probe bracket is an important factor to influence the measurement as metal parts on the probe bracket can make considerable influence to the measurement.
