This part of IEC 60076 provides supporting information to help both manufacturers and
purchasers to apply the measurement techniques described in IEC 60076-10. Besides the
introduction of some basic acoustics, the sources and characteristics of transformer and
reactor sound are described. Practical guidance on making measurements is given, and
factors influencing the accuracy of the methods are discussed. This application guide also
indicates why values measured in the factory may differ from those measured in service.
This application guide is applicable to transformers and reactors together with their
associated cooling auxiliaries.Incorporates the following:BS IEC 60076-10-1:2016
