摘要
首先介绍了霍尔器件及两种工作模式的霍尔电流传感器的基本工作原理，然后说明了已研制成功的两种智能化测试仪器——热态电气强度测试仪和接地电阻测试仪的结构组成与应用情况。
irst, the operation principle of the Hall device and two operation modes of Hall current sensor are discussed, then two kinds of the successfully developed intellectualized measuring instrument: thermal state electric strength measuring instrument and grounded resistance measuring instrument are described for its structure, make-up and application.
