摘要

有源电场探头在高压电场测量中应用广泛。笔者说明了球形和柱形有源电场探头的测量原理

计算了圆柱形探头对电场的畸变

并介绍了一种有源无线数字式工频电场测量系统。该系统所用的圆柱形探头尺寸小（准=26 mm

H=13 mm）

通过2.4 GHz无线信号通讯

可在计算机或手机屏幕上直接读出被测点的场强值

并可看到被测点电场的波形。该系统安装调试方便

性能稳定

不受环境温度影响

测量范围为0.2～3 kV/cm。在标准均匀电场中校核

测量系统线性度较好。

Abstract

Active electric field probe is widely used in high-voltage electric field measurement.In this paper

the measurement principles of the spherical and cylindrical active electric field probes are introduced

the distortion of electric field caused by the cylindrical probe is calculated

and a new active wireless digital power frequency electric field measuring system is given.The measuring system adopts a cylindrical probe with small size（φ=26 mm

H=13 mm）

transmits data throughout 2.4 GHz wireless channel

and directly displays value of electric field intensity and waveform of electric field on computer or mobile-phone screens.This system also has the advantages of convenient installation and debugging

and stable performance without the effect of ambient temperature.Its measuring range is from 0.2 kV/cm to 3 kV/cm

and check results in the standard uniform electric fields demonstrate its good linearity.
