Busbars and power cables must carry their specified operating current while maintaining acceptable temperature performance. A high-current injection system provides a controlled current source for selected current-carrying and temperature rise tests.
The system is suitable for busbar manufacturers, cable factories, switchgear manufacturers, and electrical testing laboratories.
For temperature rise applications, the system should be selected according to the required current, test duration, load characteristics, thermal measurement arrangement, and applicable test standards.
That depends on the rated duty cycle, cooling design, output capacity, and required test duration. Customers should specify whether the test requires continuous operation or short-time current injection.
The required current, test object dimensions, resistance, heat dissipation conditions, and test duration all affect the system selection.
Temperature measurement requires suitable sensors and a temperature acquisition system. These can be included if required by the project.
Yes, when the output current and duty rating meet the test requirements and an appropriate temperature measurement arrangement is provided.
It can serve as a high-current source for selected cable current-carrying and thermal tests. The test method must be confirmed according to the cable specification.
Continuous output is designed to operate at the specified current for the rated continuous duty. Short-time output is limited to a specified operating duration and cooling interval.
