Energy saving testing of contacts and other current carrying components - applying full voltage only during switching processes, regulating load resistance variations and heating power losses

摘要

For testing switching and current transferring electrical or electronic components, the full characteristic voltage is only applied during the processes of switching on and off. During the warming up phase only the characteristic current is effective with a low voltage. An electronic or electromechanical arrangement, which controls the test function, monitors the load current and regulates resistance variations of the test object and power losses caused by heating under low loading. ADVANTAGE - Ensures that only that energy which is required for testing is consumed.
