Abstract

Transformers are the most common constituents of a power system. If a trans-former is damaged, it affects the whole balance of the power system. The causes of the damage are mainly overcurrent and rise in temperature, so the objective of this project is to monitor the distribution transformer’s health in real time. The factors/ Quantities to be monitored are current, voltage, temperature and oil level of the transformer. The data is transferred with the help of NodeMCU Wi-Fi module and can be viewed in any internet browser as a web page in which data is repre-sented visually. This system can be scaled according to the demand and it helps in improvement of present monitoring systems.

34.1 Introduction

Distribution transformers are an integral part of the grid. They are respon-sible for providing power supply to the general public. Any problem occur-ring in the distribution transformer can disrupt the power supply for a certain region. Therefore, the transformer should be operated within rated conditions to improve its longevity ...
