Fundamentals of Transformer Sound And Its Attenuation

This book presents the briefly understanding the genesis of sound generation, mode of sound transmission and detailed experimental investigations to establish effectiveness of various mitigation measures being adopted across the trans- former industry. Recognizing the need for accurate estimation of transformer sound produced by the core right at the drawing board stage, the design of experiments, involving sound level measurements, was oriented towards study of the influence of various parameters, like flux density, methods of consolidation of core laminations, use of anti-vibration pads, use of sound absorbing panels, sound measurement pro- file etc.
