         Temperature Rise Test

​























The Temperature Rise test measures the increase in temperature of switchgear components when exposed to their rated current until stabilization. Its objective is to ensure the Unit Under Test (UUT) can handle this current without exceeding temperature limits, safeguarding against overheating and potential hazards. 

This test validates performance under normal and fault conditions while ensuring compliance with international standards. 

Ultimately, it supports quality assurance, thermal hazard prevention, and smooth operational functioning.
