Technical Principle of Temperature Rise Testing
Temperature rise testing is an important method to evaluate the thermal performance and current-carrying capability of electrical equipment. By applying a high current to the test object and monitoring temperature changes, engineers can verify whether the equipment meets operating requirements under rated or specified conditions.
The RDTR-CB-7000A uses a high-current output system and multi-channel temperature monitoring technology to measure temperature changes of electrical components accurately during testing.
Applications of Temperature Rise Test System
The RDTR-CB-7000A is suitable for temperature rise testing of High-voltage switchgear, Circuit breakers, Bus ducts, Electrical connectors, Current-carrying components and Other high-current electrical equipment. It is widely used in power plants, substations, switchgear manufacturers, electrical laboratories, and research institutions.
