High-voltage switchgear and controlgear -Part 37-082: Standard practice for the measurement of sound pressure levels on alternating current circuit-breakers (Superseded Redline)
Published By | Publication Date | Number of Pages |
IEEE | 2012 |
Revision Standard – Inactive-Reserved. This standard provides methods for the measurement of sound pressure level produced by outdoor alternating current circuit-breakers in a free-field environment. These methods may also be used indoors or in restricted field, provided that precautions are observed in the measurement and interpretation of the results.
