This project is focused on used for various transformer parameter measurements by using wireless mechanism, which has incorporated step-down transformer with parameter like voltage and frequency and some measurement circuit for calculating the transformer parameter. This project is achieved to observe the various criteria’s i.e voltage, frequency, temperature, oil level and prevent the transformer extra voltage and overburden and we used the GSM for transmitting data through wireless channel.If any abnormality or an emergency situation occurs the system sends SMS message to the mobile phones containing information about the abnormality.
