Hello. I am trying to get information on what type of grounding methods are typically used in industrial facilities. I realize this is going to vary with the type of industry, but just trying to get a general feel. Also what type of protection elements are being used for SLG fault detection? Residual Over-voltage? Wattmetric? Residual Overcurrent? Others?
Also, does any one have information about utility distribution system grounding practices and what percentage of distribution systems might be ungrounded or high Z (or R) grounded? If so, what elements are being used for SLG fault protection?
Thanks in advance for your input!
