GE Arc Vault™ Protection System
An innovative step forward in arc flash protection!


To address the increasing concerns and standards around arcing faults, GE challenged our Global Research Center to develop a new, “active” method of detecting & removing an arcing fault. The goal was to develop a technology that would, in simple terms, reduce the potential for injury and equipment damage. The result is an innovative product called the GE Arc Vault™ Protection System. This article will outline some basic arc flash mitigation techniques, and culminate with a description of the new GE technology. It should be noted from the onset that this technology is currently in the prototype phase and that the discussion covers applications of 600V & below.

The Three A’s of Arc Flash
In 2007 GE conducted a survey of industry professionals working in facilities related to the oil and gas industry, pulp and paper industry, and power generation. We asked questions that identified:


• Whether or not they knew the current hazard risk categories in their facilities
• Whether or not they had conducted a hazard risk analysis in their facility
• What actions, if any they had taken as a result of the hazard risk analysis
• What were the most important benefits they would expect from reducing the hazard risk category of equipment
• Identify the solutions currently in place to reduce the risk of arc flash injury.


The study results revealed what we called the problematic three A’s of arc flash. Before we get into the study and it’s results, let’s review the basics about arc flash.

Arc Flash Mitigation with Entellisys™
As time goes by, we are finding a growing number of customers that are becoming more concerned with arc flash and the injuries that can occur. We all hear the questions “Is this really a dangerous situation?” or “Does it really concern me or my facilities?” The answer is yes. Arc flash is a condition that exists with all pieces of electrical equipment. The real question becomes, how do I reduce the threat? Today, we are going to review how using a multi-layered approach in the design and selection of switchgear can impact operator’s actions as well as reduce the arc flash incident energy level.
