Abstract

The paper presents magnetic flux density and current measurement principles and procedures during 345 kV circuit breaker maintenance operations. Field and scale model measurement techniques are described and discussed. Two case studies are presented; they are related to vertical-plane magnetic flux density measurements during the maintenance of a deenergized live-tank SF₆ circuit breaker in a 345 kV substation. Field and scale model measurements, and calculations are compared and discussed
