Transformer is a important part of the transmission and distribution system. Transformers Monitoring for problems before they occurs can prevent the faults that are expensive to repair and results in loss of service. Transformers are the essential part of power transmission network and expensive, as the cost of power failures. Because of much cost of scheduled and unscheduled maintenance, especially at the remote sites, the utility industry began investing in instrumentation and monitoring of the transformer. in this project we are implementing and of a mobile embedded system to monitor key parameters of a distribution transformer like load currents, oil level and ambient temperature. The idea of monitoring system integrates a global service mobile Modem, with a single chip microcontroller and different sensor interfacing. It is installed at the distribution transformer site and the above parameters are recorded using the analog to digital converter (ADC) of the embedded system. The parameters are processed and recorded in the system memory. If any emergency situation occurs the system sends SMS message to the mobile phones containing information about abnormality according to some predefined instructions which are programmed in the microcontroller. This system mobile will help the transformers to operate perfectly and identify problems before any failure.
