GSM Based Condition Monitoring of Transformer

In normal ways all the Industrial or Electrical machineries are controlled by the manual operation. Hence there is step by step progress but most of the time there is not actually instant cooperation between system and operator in case of emergency or fault type situation .Therefore we are designing a system where there exits communication between system and operator. For this we are using Transformer, microcontroller, logic level converter and GSM i.e. global system for mobile communication modem. This GSM modem helps to monitor transformer health by sending message to the system. As we know, transformer is a major component of power system and its correct functioning is vital to system operations. To reduce the risk of unexpected failure and the ensuring unscheduled outage, on-line monitoring has become the common practice to assess continuously the condition of the transformer. This paper presents design and implementation of a mobile embedded system to monitor and record key operation of a distribution transformer like overvoltage, over current, temperatures, fall of oil level. Also it is important to keep an eye on transformer health when operator is not present actually at transformer site so we are introducing system named as two way communication systems between transformer and operator through GSM modem where person can ask any related parameter value of transformer health by sending message to the system. This system is designed to send SMS alerts whenever related parameter value exceeds the predefined limits.
