【摘要】 本文介绍高压下工频电场强度测量仪。它是用一个三维的球形传感器采集高压下的模拟电场强度信号,通过光导纤维传送到低压接收机进行解调和自动测量的一种仪表。测量的范围为0～450kV/m,测量的精度为3％×读数+1kV/m它的特点是可以用于高压线路下及变电站等内空间电场强度的测量。更多还原

【Abstract】 This paper prensents a new field sensor for the measurement of time dependent periodic electric fields with a optic fiber data transmission link. First the basic theroy of the measurement method and the geometry of the probe is described, further on the circuits of the measurement system are presented and finally the charaters of the measurement system are given.更多还原
