There are many technical challenges in the application of secondary circuits for energy metering in distribution and transformation systems,such as excessive reliance on manual labor for on-site inspection,manual operation for adjusting the ratio of multi tap current transformers,low efficiency in handling circuit open circuit faults,and cumbersome wiring structures.To address these challenges,the article explores the use of intelligent terminals and remote control technology as a solution.It deploys intelligent monitoring modules to achieve remote calibration of energy meters,develops automatic switching devices to optimize the ratio adjustment process,constructs a remote short-circuit protection system to enhance the ability to handle open circuit faults,and simplifies the circuit connection method using standardized plug-in technology.Test data shows that this scheme can improve detection efficiency by 65%,control the switching time of the transformation ratio within 3 seconds,compress the response time of open circuit faults to below 500 ms,and reduce the occurrence rate of wiring errors by 82%,providing reliable technical support for the intelligent upgrade of the secondary energy metering system.
