Technical DiscussionTechnical Discussion

How does your plant/utility use Limitorque Technical Update 93-03 in determining MOV torque capability? Does your plant take credit for a lower current associated with elevated temperatures? If yes, is the current loss based on 25°C or 40°C? What temperature is the torque de-rate based on, i.e. 25°C or 40°C? Does your plant analyze motor capability at nominal temperature and/or maximum temperature?
