| Abstract: | Measurement and control device is mainly used to realize the transformer substation remote measurement and control function such as remote communication, remote measure, remote control. If the device has defect or breaks down, main transfomer circuit break misoperation would happened which has influence on safety operation and reliability. With an example of main transfomer circuit break misoperation caused by aging measurement and control device, reason for switch misoperation was analyzed and treatment was proposed to ensure equipment operation. |
