Abstract :
This paper presents the following aspects of Load noise in power Transformers: (1) Characteristics of Load Noise, (2) Contribution of load noise to the total noise of a transformer and why it has not been well - recognized by the industry in USA and some other parts of the world, (3) Accurate calculation of load noise and the need for the accurate calculation, (4) Accurate measurement of load noise, (5) Magnitude of variability of load noise, (6) Parameters affecting load noise level and means to reduce load noise, and finally (7) Need for the inclusion of load noise in the IEEE Standards and customer specifications.
