The monitoring relays are easily configured via potentiometers and rotary switches on the front face of the modules 检测继电器可以通过模块前面的电位计和旋转开关轻易地设定。
2.
Operational conditions of the monitoring relays are displayed via leds for supply power transformer voltage , relay status , fault type and delay times 检测继电器的操作情况中的供电变压器电压、继电器状态、故障类型和延迟次数可以通过led显示出来。
3.
The system is applied to a means of online fault diagnosing and a measure of real - time monitoring relay protection sensitivities . and following works have been illustrated 该系统为运行人员提供了一种在线进行故障诊断的方法以及在线对保护灵敏度进行监测的手段。
