Is Electrical Switchgear Safe?

From Flir Systems Incorporated
 

 
In today's infrared community, we talk a great deal about "What is safe?" when it comes to electrical equipment and internal-arc flash. Thermographers generally assume that with the covers and doors closed, the switchgear is in a totally safe work condition. This paper explores the differences in switchgear with respect to internal-arc flash and how this affects the safety of the thermographer. The presentation incorporates a worked example of an internal-arc flash test on a piece of 15kV switchgear incorporating infrared windows, including actual video footage of an arc-flash test occurring. Infrared thermography of electrical switchgear is a well-known and accepted predictive maintenance technique. Working with any kind of live, electrical equipment incorporates an element of risk, but how does this risk manifest itself in relation to arc-flash and infrared thermography? Is our electrical switchgear totally safe? Today, the infrared community talks a great deal about "arc fault" or "arc flash," but to understand what an arc
