Design monitoring of distribution transformer load by messenger based on microcontroller atmega 128

In order the distribution process of electricity to customers run properly, the distribution transformer should be noticed. But there are some obstacles such as the amount of the transformer is not proportional to the number of officers and the location of transformers are scattered in various places. These problem make officer hard to measure development of peak loads on old customers and new customers. Currently the growth of the transformer load is still not monitored properly. Therefore electric company need technology that is able to monitor transformer load. This research produces a tool that enables officers easier to monitor distribution transformers load in real time and throughout 24 hours. The output is visual data in the form of indicator lights that facilitate monitoring transformer load and data will sent periodically to the office server. If transformer is overload, tool will send warning message to officer so officer can take safety action in short time and can decreasing the risk of fire due to damage of transformer.
