GB/T 33981-2017 Standard practice for the measurement of sound pressure levels on high-voltage alternating current circuit-breakers
Abstract
This standard specifies the measurement method for the sound pressure level of high-voltage AC circuit breakers. This standard applies to AC circuit breakers designed to be installed outdoors in a free-field environment and with a system voltage of 3,000 V or higher, which generate sound pressure levels. If protective measures are used during the measurement process and the effects of these protective measures are taken into account in the analysis of the results, these methods can also be used for AC circuit breakers installed indoors or in confined environments.
