Monitoring and Control Of 500 KVA Transformer Through GSM Based Raspberry Pi Controller

Date : Nov 2019 - Nov 2020

This project is concerned with the design and implementation of mobile interfaced systems to monitor and record key parameters of the 500 KVA Distribution Transformer, such as load current, voltage, oil level, vibration and temperature of the transformer. The idea of this monitoring system, which integrates a Global Mobile System (GSM) modem with a standalone single-chip Raspberry PI3 controller, works like a mini-computer and the various sensors. This system is installed in the location of distribution transformer and above-mentioned parameters are recorded by an Analogue to Digital Converter (ADC) of the embedded system, the parameter obtained is proceed and recorded in the system memory. When there is any abnormal or emergency condition, the system is sending a short message through GMS based mobile network i.e. SMS to the mobile phone, that contain the information about the such problem. This corresponds to some standard instructions that are programmed in the Raspberry Pi3 controller. The mobile phone system alert us from the abnormal condition which has occurred.
