Test Systems for Temperature Rise Tests

Test systems for temperature rise tests are used for testing switchgears and bus bars under nominal load or at a defined overload in an endurance test.

Depending on the desired regulating accuracy, high-current supplies consist of a coarse stage and a fine stage in order to increase the resolution for the current regulation. The coarse stage is roughly adjusted to the desired current. The fine stage performs the fine adjustment (automatic stabilisation of the output current).The sine wave of the test voltage is essential for the reproducibility of your measurements.

Transformational testing systems, with amplitude adjustment to the voltage setting, offer the advantage of a constant clean sinus wave from the input all the way to the test item. The measurements are therefore reproducible and no EMC problems will arise.

  • Rated currents up to 30,000 Ampere AC
  • Rated currents up to 22,000 Ampere DC
  • Separate modular set-up of control, variable and high-current unit
  • High-current unit in protection type up to IP54, protection class 2, installation in direct proximity to load is possible – thus keeping cable and bus bar connections short and reducing voltage dips and bus bar losses.
