- Advanced knowledge - Understand advanced control schemes and arc-resistant switchgear.
- Arc-Resistant Switchgear Construction or Arc-Detection Devices? [PDF] Arc-resistant switchgear must resist two phenomena — increased internal pressure and burnthrough. These two phenomena operate in two different time frames. Burnthrough is a relatively long-time event. The test to prove resistance to burnthrough is of one second duration.
- Arc-resistAnt switchgear tested to ANSI C37.20.7 & NFPA 70E [PDF] Arc-resistant switchgear can assist with the first step effort by providing enhanced safety conditions when the operator task involves energized equipment and possible exposure to an arcing fault.
- Why is Continuous On-line Monitoring of Partial Discharge in the Switchgear Necessary? This article examines the advantages of continuous over periodic partial discharge (PD) testing.
