Design and implementation of a remote monitoring system of a Distribution Transformer.

Abstract

Our proposed idea presents the design and implementation of a remote monitoring system to monitor load currents, over-voltage, transformer oil level and oil temperature as well as the health of protection devices like fuses and surge arresters. The remote monitoring system integrates Global Service Mobile (GSM) Module with single-chip microcontroller and sensors. It is installed at the distribution transformer site. The output values of sensors are to be processed and recorded in the system memory. A system is programmed with some predefined instructions to check abnormal conditions. If there is any abnormality on the system, the GSM module will send SMS (Short Message Service) messages to designated mobile telephones containing information about the abnormality according to the aforesaid predefined instructions. This system will be an advanced step to automation by diminishing human dependency. As it is a wireless communicating system, there is no need for large cables which are of high cost. Thus, this system offers a more improved transformer monitoring.
