With the efforts being done to make the existing power network smarter and efficient, thermal monitoring of transformers has become the demand of the day in the field of transformer engineering. Theoretical methods available and practical measurement techniques will not suffice, hence the development of thermal modeling techniques that can measure the thermal profile across the transformer at desired...
chapter
Heat dissipation is always a problem in large power transformers. Increased market competency demands for accurate determination of the thermal profile across the transformer. This paper presents a thermal model to simulate the thermal behavior of the electrical utility transformers. The thermal model is arrived at using the principle of thermal electrical analogy and the fact that the losses in the...

The present work reports studies on the fluidization of mixtures of biomass and sands. The biomass materials used are rice husk, sawdust and groundnut shell powder, and the sands employed are of two different densities and particle sizes. Experiments are carried out in a 5 cm ID fluidized bed column to determine the minimum fluidization velocities. The percentage of biomass materials in the mixtures...

The precision required for residue operations is primarily associated with resistive components and operational amplifiers. However, technology has advanced to the point that analog components can be built to an accuracy of less than one tenth of one percent (at least with discrete components). Companies are attempting to build DAC'S with fifteen (15) bit accuracy which will settle to the least significant...
