摘要
介绍了一种新型的分布式电容型设备在线监测系统。系统借助于给每台下位机供电的交流电源,可以不必把电压互感器二次信号线引至每台下位机内。文章论述了系统的工作原理,对下位机硬件电路和软件设计也做了说明。
The article introduces a new type full-distributed online monitoring system for capacitive equipments. By the help of AC power line,the system need not to link the three phase secondary lines to every measuring devices installed on equipments.The article demonstrates principle of the system and designing of the hardware circuits and software as well.
