Alabama Power Opens Up to DGA in a Box

摘要

Southern Company gets timely and accurate results by performing transformer checkups in the field. DISSOLVED GAS ANALYSIS IS A NONINTRUSIVE TOOL used to determine the internal condition of power transformers. Over the years, Southern Company Transmission has made tremendous progress in refining its initial program. Managers who were once skeptical of our recommendations to remove a large generator step-up unit (GSU) from service based solely on dissolved gas analysis (DGA) results now rely on us to routinely make these decisions. Quite often, we have been able to repair critical units that eventually would have failed if left unattended. Although we don't catch all the problems, as some units seem destined to fail in spite of our efforts, the ability to obtain a rush sample and have results within an hour would definitely give us an upper hand.
