SNZ - AS/NZS 60076.10.1

Power transformers Part 10.1: Determination of sound levels – Application guide

active, Most Current
Organization: SNZ
Publication Date: 26 May 2023
Status: active
Page Count: 52
scope:

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.
