Abstract：Considering the requirement of data transmission reliability and real time in distribution transformers, A monitoring system of distribution transformer in real time based on GPRS was introduced. The design of monitoring system was described in detail. The system was made up of monitoring equipment based on AT89S52 MCU, GPRS module ( EP120P) and control center sever. It utilizes the direct connection between GPRS network
and Internet to realize data acquisition and transmission. The experiment proved that the system has the characteristics of the high-speed transmission, the good dependability, the real time characteristic and the practicability. The system satisfies the data transmission requirement of the monitoring system of distribution transformer.
