is there a way to check the resistance of a ground rod other than using a ground rod resistance meter,thanks--bob

smur, if the voltage between a-b is 208,and b-c is 208,and c-a is 208,then it may indeed being a delta grounded system,is there a neutral? ,the system i work on is a 480 volt delta ground there is no neutral,the grounded phase is not a ground!!to get 120-240 for lighting,tools etc,we use a...

hello smur,what reading do you get a-b-c etc.?

thanks guys.in xcel area we tried cold sequence metering but they backed off ,with the exception of 480 3 phase is cold sequenced.fault currents in excess of 10,000 amps is uncommon in residential application .hence, the hot sequence . ct are to be hot sequenced,ive been told both reasons as...

why is cold sequence not allowed on ct metering per power companies/? is it a safty issue or tampering deterent,thanks-bob
