IEEE C57.136-2000

This document is intended to provide guidelines for selecting suitable external methods for noise reduction in liquid-immersed power transformers and shunt reactors rated over 500 kVA. Many noise abatement procedures are described that are presently available for achieving various levels of noise reductions in transformer and shunt reactor installations. For background information, this document will also discuss the noise producing sources within the transformers and reactors.

The purpose of this document is to provide guidelines for reducing the noise level by external means on liquid-immersed power transformers and shunt reactors rated over 500 kVA. This document will also describe noise abatement procedures that are presently available to reduce noise levels in transformers and shunt reactor installations. Background information about noise producing sources within the transformers and shunt reactors will also be discussed in this document.

New IEEE Standard - Superseded. Reaffirmed September 22, 2005. Guidelines are provided for the selection of suitable sound reduction methods in oil-immersed power transformers and shunt reactors over 500 kVA. Sound-producing sources within transformers and reactors are discussed. Sound abatement procedures are described for achieving various levels of sound reduction in transformer and shunt reactor installations.
