FAQ
1. What is an Automatic Temperature Rise Test System?
An Automatic Temperature Rise Test System is a specialized high-current testing system used to apply a stable AC or DC current to electrical equipment and monitor its temperature rise during operation. It is designed to evaluate thermal performance and verify whether the tested equipment meets specified temperature-rise requirements.
2. What is the purpose of a temperature rise test?
The temperature rise test is mainly used to determine whether electrical equipment can operate safely under rated or specified current conditions. It helps evaluate the equipment's heating characteristics, heat dissipation performance, and thermal stability. For transformers, temperature-rise testing is also used to evaluate winding and oil temperature rise.
