Temperature rise test for lv switchgear
WebTemperature Rise Test on Medium Voltage Switchgear Assembly Based on IEC Standard Abstract: IEC 62271-1 clause 6.5.2 states the measured temperature difference between the main circuit and the temporary test connections at a distance of 1 m should not exceed 5 K. Webe) For LV switchgear, the temperature rise test limits of connections and contacts are not defined in a clear table to be used by the testing lab. So, most of the testing laboratories simply present the test results but do not state if the equipment passed or not.
