IEEE Guide for the Mechanical Acoustic Imaging Testing of High-Voltage Reactors
Full Description
Scope: This guide defines test methodologies and technologies for mechanical acoustic imaging. Acoustic fault recognition mechanisms using acoustic imaging technology are described, enabling, for high-voltage reactors, the identification and diagnosis of abnormal radiated noise in a reactor structure caused by mechanical structural abnormalities such as loose structural parts, metal foreign bodies, and loose leads. Additional use cases and test considerations are described to support fault acoustic signal testing of power transformers, switchers, and gas-insulated substations (GIS).
Keywords: acoustic imaging, high-voltage reactor, IEEE 2824™, microphone array, noncontact measurement, sound signals
