Transformer failures are particularly severe, which can lead to endangering people as well as disrupting power supply to a large number of customers. Therefore, it is necessary to develop tools for monitoring, detecting and early warning of abnormal conditions in operation of transformers, so that the operators can handle them before the faults occur. This paper presents the results of research, design and fabrication of a monitoring equipment to transformer, thereby helping to reduce abnormal incidents and support maintenance and maintenance according to conditions (CBM). The main objective of this device is to detect early abnormalities that cause malfunction and damage to the transformer. The important parameters of the transformer are monitored through the field-installed equipment. Main functions are programmed and designed on electronic circuits. Monitoring programs are written on software to help operators use conveniently. The equipment was installed and tested at the actual transformer. Test results realize proposed functions of monitoring, management and operation of the transformer.
