Abstract
This companion paper to that presented at the 2009 IEEE IAS Annual Meeting describes new differential protection solutions for electric arc furnace (EAF) power systems that use Rogowski Coils as current sensors. These novel solutions provide multiple protection zones, covering the entire EAF electric supply system. The protection philosophy includes multiple differential zones of protection such as cables serving the EAF vault, series reactors, EAF transformers (including all power apparatus in the protection zones), and busbars.
