Remote monitoring has been implemented in many areas. This paper introduces its specific application to a three-phase 10-kVA energy-efficient switchable distribution transformer. A designed embedded system and embedded Ethernet have been implemented to achieve a compact remote condition monitoring for the transformer. The embedded system performs acquisition of voltages, currents, and temperatures,...
Temperature measurements are one of the most significant factors in condition monitoring and protecting transformers as well as estimating their life expectancy. With switchable transformers, it is also significant to carry out temperature monitoring to protect the switching devices. This paper presents techniques to manage temperature measurements of the windings and core of a 3-phase 10kVA switchable...
