Transformer Monitoring and Controlling with GSM Based System

Distribution transformer is an important part for electrical energy transfer in electrical power systems. So to protect the distribution transformer from damage the overloading currents, over-heating of transformers oil and high voltage spikes. So, relevant protection of transformer is very important for continuity of power supply. In this protective strategy is implemented by using of Arduino controller that is not so costly and massive high speed with high accuracy. The controller sense the temperature of transformer and current of load continuously. The rating of voltage and current reaches from its pre-set values, protection scheme operates and trips the load in abnormal condition. As temperature reaches to threshold value set in system, a fan would turn on for the cooling of the heated transformer. To occur the over current fault we increase load by using bulbs. If any emergency or abnormal conditions occur the system sends information through SMS to the mobile phones, by using GSM Modem. At the end, successful results have been justifying the proposed technique and identify problems before any failure
