IEC Standard High Current Temperature Rise Test Bench for HV and LV Switchgear, Busbar and Circuit Breaker – Automatic Heat Run Testing System

The High Current Temperature Rise Test Bench is designed to verify the thermal performance of electrical equipment under rated or specified operating current.

It is particularly suitable for manufacturers of high-voltage switchgear, low-voltage switchgear, busbars, circuit breakers, disconnect switches and other current-carrying assemblies.

The equipment provides controlled current loading and multi-point temperature measurement to evaluate temperature rise during a heat-run test.

Current industry solutions commonly position temperature-rise systems around IEC 62271 for switchgear and related high-voltage equipment, while other product categories may use standards such as IEC 61439 or IEC 60947 depending on the test object.

Which IEC standard applies?

The applicable standard depends on the equipment being tested. For switchgear, IEC 62271 is an important reference; for low-voltage assemblies, IEC 61439 may be applicable. The exact clause should be confirmed according to the customer's product and certification requirements.

Can the test bench be used for type testing?

Yes. The system can be engineered for type-test applications.

Can it be used for factory routine testing?

Yes. The control system can be configured for repeated production testing.
