Abstract: 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.
