Analysis of Natural Frequency for Three-Dimensional Model of Transformer Winding Using FEA
Abstract: AbstractPower transfer winding is prone to a number of events of a short circuit. However, over a period of time, capabilities of winding to withstand forces generated during such events decrease. In order to understand the behavior of winding at excitation, study of natural frequency is an important parameter. In this paper, winding’s radial and axial modes are studied with the help of finite element approach. Three-dimensional (3D) and two-dimensional …

PROJECT PLANNING AND CONSTRUCTION USING ROBOTICS AND AUGMENTED REALITY
Abstract: The construction industry is based on human resources, specifically for on-site construction processes. The conventional construction practices require an absolute amount of workforce and skilled labour to achieve the aimed efficiency in terms of construction duration and cost, and building quality. Besides, lack of workforce and sufficiently skilled labour can affect the overall duration, cost, and quality targets. Therefore, based on these issues, advanced robotic technologies have been developed to …
