Oil Based Transformer Health Monitoring System

The fault free operation of transformers gives more impact on economic and safety in power supply to utilities and industrial and domestic consumers. A sudden breakdown/fault in a power Transformers will affect unexpected production interruption, down time of the equipments in industries and the repair/replacement of the transformer, it may lead to huge investment and expenses. The insulating oil in a transformer can tell a lot about the actual state of transformer and its longevity. This proposed work mainly focuses on condition monitoring of transformer oil by using PLC, SCADA with suitable sensors for sensing parameters of oil like moisture content, temperature can be found. By using these data the analysis can be done. In addition to this, this system incorporated with the GSM module to alert the maintenance authority when the transformer under goes faulty condition, so that the transformer can be saved from the huge damage.
