Medium Voltage Generators are not designed to withstand full fault current during a single phase to ground fault. This is the main reason that medium voltage generators are connected to a system with either low or high impedances. There are many methods to ground generators. To find out what these methods are, please download this free whitepaper.</p></div> <div class="og_rss_groups"></div><p><a href="http://ecmweb.com/whitepapers/reducing-arc-flash-risks-electrical-maintenance-safety-devices-0" target="_blank">read more</a></p> http://ecmweb.com/whitepapers/reducing-arc-flash-risks-electrical-maintenance-safety-devices-0#comments Whitepapers Thu, 06 Mar 2014 21:34:00 +0000 42851 at http://ecmweb.com
