摘要
介绍了一种用于检测电流互感器极性的便携式新型智能仪器。装置基于直流法,利用数字采样获取电气参量,并以Atmel公司生产的ATmega8L高性能单片机为核心,将原来的测试设备集成于一体,为现场检验提供极大的便利。
A novel intelligent instrumentation of current transformer （CT）is proposed. The measurement system is based on direct current method to sample electronic variables. ATmega8L single chip processor can be introduced to fulfill the inspection goal by replacing separate instruments. The calibration instrumentation can provide great benefit on site.
