The best of this year’s Doble Circuit Breaker Conference
Circuit breakers need to operate quickly in order to clear faults and protect expensive electrical apparatus. Yet, under normal conditions, a breaker may only be in operation for less than ten minutes throughout its life. Testing circuit breakers gives electric utilities the necessary assurance to know if breakers can and will perform when needed.
This mega feature, presented by Electricity Today Magazine and the 21st Annual Doble Circuit Breaker
Test and Maintenance Training Conference (formerly Finepoint), focuses on maintenance, testing, and
asset management programs for circuit breakers. Learn more from the industry professionals contributing
content to this feature at various sessions during this year’s Doble Circuit Breaker Conference.
