Active noise control in practice: transformer station

摘要

Based on literature and extensive measurements at a specific transformer two concepts regarding anti noise have been developed. These concepts have been tested in the Peutz acoustical laboratory, and on site with an experimental setup for anti noise at large transformers. Noise measurements show that a reduction of 5 dB can be achieved in all directions. Additionally, by directing the noise emission, a reduction of 10 dB can be achieved in one specific direction. This experimental project was part of a broader demonstration project regarding the practical application of different types of sensor technology.
