Abstract: The SiC deexcitation resistor is constituted by multiple SiC resistor chips connected in serialparallel mode. Their current equalizing and energy equalizing performances can be examined by temperature characteristics. Aiming at the temperature characteristics of current SiC deexcitation resistors, a new offlinedetection method was proposed. The new method is economical, practical, safe and simple.

Key words: SiC deexcitation resistor, temperature characteristics, temperature equalizing coefficient, off-line detection
