What conditions and standards require the use of a temperature rise meter?
The temperature rise test is an experimental method used to evaluate the thermal performance and stability of electrical equipment or its constituent parts. During normal operation of electrical equipment, a certain amount of heat is generated as a result of the passage of current through the resistors, capacitors, windings and other constituent parts of the circuit, resulting in an increase in the temperature of the parts. If the temperature of these components rises too high, it may lead to damage, failure, or even fire and other safety hazards, so it is necessary to carry out temperature rise tests on electrical equipment or its constituent parts to ensure their safety and reliability under normal use conditions.
SH9408A multifunctional temperature rise measuring instrument based on IEC 884-10 and UL498 and other electrical accessories developed by the relevant standards. Can be used to assess the electrical accessories in the load current connected to its surface heating, electrode temperature rise according to the standard requirements, can effectively detect the plug and socket socket is thin, plugs and sockets are well coordinated. It can also be compatible with the temperature rise test of circuit breaker, automatically calculating the temperature rise value, automatically recording, setting the test start time and end time and setting the steady state conditions.
This tester consists of current regulation control part and temperature sampling measurement part.

Temperature rise test usually needs to be carried out under specific conditions, such as setting certain electrical parameters (voltage, current, frequency, etc.) and energising and running electrical equipment or its constituent parts for a period of time to measure the surface temperature change. Through the measured temperature data, the thermal performance and stability of the electrical equipment or its components can be assessed to determine whether it meets the safety standards and design requirements.
At the same time, the temperature rise test can also be combined with other test items, such as current, voltage, power, efficiency and other tests, to assess the overall performance of electrical equipment.
The temperature rise test is a very important part of the manufacturing and use process of electrical equipment. Firstly, the temperature rise performance of electrical equipment and its constituent parts is an important factor that directly affects the safety and reliability of electrical equipment and must be fully verified and confirmed. Secondly, the temperature rise test results can also provide a basis for the optimal design of electrical equipment and improve the production process to improve product quality and performance. Finally, for electrical equipment that needs to comply with relevant safety standards and regulatory requirements, temperature rise test results can also be used as an important reference for product certification and compliance assessment.
