GSM Based Transformer Monitoring System

Transformers are a vital part of the distribution and transmission system. Transformers monitoring the problems before they can occur can prevent failures that are costly to repair and result in a loss of service. An innovative design to develop a voltage, current and temperature monitoring system, oil level, distribution transformer theft at a substation, and to protect the system from the parameters mentioned under GSM that are used in this document. This portable system will help transformers compete normally and identify problems before a catastrophic failure. The proposed design is developed so that the user easily recognizes the distribution transformer suffering from a problem. This system deals with the design and implementation of an embedded cellular system to monitor and record the main parameters of a distribution transformer such as load current, over current, oil level, winding temperature, and ambient temperature. The idea of an online monitoring system integrates a global mobile service (GSM) modem with a single microcontroller of different chips and sensors. It is installed at the distribution transformer site and the above parameters are recorded using the analog-to-digital conversion (ADC) of the integrated system. The gained parameters are processed and recorded in the system memory. If an anomaly or an emergency occurs, the system sends SMS messages (short message service) to cell phones that contain information about the abnormality according to some predefined instructions programmed in the microcontroller. This portable system will help transformers to compete normally and identify problems before any failure.
