Abstract A kind of high voltage transformer nameplate observer based on combination of digital camera module is designed to overcome the disadvantage of observation of running transformer nameplate in the current energy metering work. It can realize the observation of the transformer nameplate without power outage and reduce the number of power outages, improving the efficiency and security of transformer nameplate observation. MT9M001C12STM is used as the image sensor, the DSP image processor control circuit sends the image information to screen to display, completing the transformer nameplate information observation. The test results showed that the transformer nameplate observer is insulation qualified and image clarity can meet the requirements of the transformer nameplate observation.
