GB/T 24276-2009 A method of temperature-rise assessment by extrapolation for partially type-tested assemblies(PTTA)of low-voltage switchgear and controlgear
Abstract
This standard specifies the extrapolation method for determining the temperature rise of low-voltage switchgear and controlgear (PTTA) subjected to partial type testing. This standard applies to enclosed low-voltage switchgear and controlgear (PTTA) subjected to partial type testing, or to partitioned cabinet units of PTTA without forced ventilation.
