A processor for PIC microcontroller in field programmable gate array (FPGA) is designed; its application is implemented and discussed in this paper. The application is monitoring of transformer parameters in real time using global system for mobile (GSM) module. Energy between two or more circuits is transferred through electromagnetic induction in transformer. For high voltage electric power transmission, Transformers are important and economical in practical. In high power transformer, it is essential to monitor various parameters to ensure safe and reliable operation. An embedded system has been designed and monitored by real time for the transformer, that carries out acquisition of voltage, current, and temperature of transformer and process the acquired data. This system enables the fault and status reporting via GSM module, allowing the most cost effective communication infrastructure for monitoring and acquiring data of transformer. In the prototype hardware kit, a small prototype transformer is used. The input and output current, voltage and temperature of core are monitored and transmitted through GSM. © 2017 Elsevier B.V., All rights reserved.
