Abstract
Transformers form an integral part of the electrical
power grid are widely employed in a variety of power-system
applications inter alia power generation and distribution systems,
and arc- and induction-furnace applications. Transformers are
among the most expensive components in power systems but the
protection and health requirements thereof are still catered for
by traditional auxiliary protective devices and cooling control
systems. This paper reports the development of an IoT-based
condition monitoring system that offers advanced protection and
control features. The condition monitoring system is intended to
directly contribute to enhancing the lifespan of the transformer
by detecting fault conditions at an early stage before catastrophic
failure can occur and by ensuring that the quality of the
transformer’s insulation is preserved for a greater period through
improved cooling techniques.
