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...
Experimentations and performance analysis following designs and developments of energy efficient switchable distribution transformers are of first significant step as it reveals improvements, such as in energy efficiency, through the use of unique configurations and switching devices in the transformers. This paper explains a personal computer based application and hardware, using lab VIEW and a data...
Control systems of switchable transformers play a prominent role in achieving precise timings for switching actions and providing monitoring and protection for the transformers. Since the first energy efficient distribution switchable transformer was designed and built, several designs of control system have been introduced. This paper presents a further development of the control system design which...
