IoT-Based Power Monitoring and Lifetime Estimation of a Distribution Transformer in Building Scale

Transformers have a very vital role in the distribution of electrical energy. For this reason, a suitable transformer maintenance method is needed. Transformer condition needs to be known quickly and accurately to avoid damage due to aging and faults. In this work, a procedure to design for monitoring transformer conditions is proposed. The device can be accessed real-time through online. The calibration process is carried out to ensure measurement accuracy compared with standard calibration measurement tools. Monitoring features include power quality and harmonics, allowing the user to maintain the transformer. This equipment lets the user know the transformer condition in a building. The health assessment includes the harmonic factor. From the experimental result, the prototype is still within the error limit.
