A current industry example describes three-phase switchgear temperature-rise systems in configurations such as 3*3000A, 3*5000A and 3*6300A, with higher-current configurations also available.

Why use three-phase temperature rise testing?

Three-phase testing can reproduce the operating conditions of three-phase electrical equipment and allow engineers to evaluate thermal behavior across phases.

Can the three phases be controlled independently?

The control architecture can be customized according to the test requirements.

Can busbar and switchgear be tested together?

Yes, if the system capacity and test configuration are suitable for the complete test object.
