Abstract

Abstract:

ECRH arcing protection system consists of arcing detector, A/D converter and logical processing unit. The response time of the arcing detector is less than 2μs, and the response time of the A/D converter and logical processing unit is less than 1μs. The system could switches off all related power supplies within less than 20μs from outputting the protection signals.

Key words: Arcing, Protection signal
