Transformer Fault Early Warning System Model Using GSM Network

Abstract

This paper presents the design and implementation of a mobile embedded system using an Arduino microprocessor to monitor and record key operational indicators of a distribution transformer, such as transformer oil level, temperature and vibration of a distribution transformer in a substation. If there is any abnormality or an emergency situation, the system sends SMS (Short Message Service) messages to designated mobile telephones containing information about the abnormality of the mentioned parameters. Providing early warning of the abnormality of the distribution transformer can be accomplished by shutting down the entire unit with the aid on-line monitoring system integrates with Global Service Mobile (GSM) Modem. Furthermore, the design generally consist stand-alone single chip microcontroller, modem and sensor packages located on distribution transformer site. In general, the design is developed for the user to easily recognize the distribution transformer that is suffered by any high vibration and rise in temperatures and located in remote or suburban area which is rarely and hard to reach for manual monitoring. The ultimate objective is to monitor the transformer oil level and temperature of 24 hours, 7 days a week continuously besides the current and voltage parameter which included in basis monitoring system.
