Circuit Breaker Induced Switching Transients

Date: Thursday, August 25th, 2011

Location: SRP Information Services Building (ISB), 1600 N Priest Dr, Tempe, AZ 85281

Speaker: Scott Brady, Eaton Electrical Inc.

Topic: "Circuit Breaker Induced Switching Transients"

The presentation will focus on switching transients associated with circuit breakers operation. Recently this phenomenon has been attributed to a significant number of transformer failures involving primary circuit breaker switching. This presentation will review these recent transformer failures due to switching transients to show the severity of damage caused by the voltage surge and discuss the common contributing factors. Several techniques and equipment that have proven to successfully mitigate the switching transients will be reviewed.
