Arduino based Condition Monitoring of Different Parameters of Distribution Transformer

Abstract

A remote monitoring system for the distribution transformer is developed and built for the monitoring of certain parameters of the transformer such as, temperature, oil level status, fuse cutoff and load variation. The system consists of two units; transformer monitoring unit and data collection unit. The units are based on Arduino in addition to solid state components used for handling sensors, power backup and GSM section for the data communication module. The sensors include, current sensor module, potential transformer, temperature sensor chip and oil level sensor. The system is installed at the distribution transformer site and by measuring above parameters it will help the utilities to optimally utilize transformers and identify problems before any catastrophic failure.
