A Methematical Model of Transmission Line Audible Noise Part 2: Comparison with Experiment

This part of the paper compares the model developed in Part 1 with experimental results obtained by a number of investigators. The shape of the curves predicted by the model is shown to be in good agreement with results showing audible noise as a function of gradient or rainfall rate. Simple curve fitting is used to find values of the constants in the model using published audible noise data. A single equation predicting audible noise for multiconductor lines in saturated conditions is presented. Implications in the areas of interpretation of existing data, conductor testing and conductor design are discussed.
