IEEE/IEC 62271-37-082-2012 High-voltage switchgear and controlgear -Part 37-082: Standard practice for the measurement of sound pressure levels on alternating current circuit-breakers

IEEE/IEC 62271-37-082-2012 Высокое напряжение и аппаратура управления -Частью 37-082: Стандартная практика для измерения уровней звукового давления на переменном ток автоматических выключателей

This part of International Standard 62271 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.
