We have a concept of placing ground ring or loop (bare copper conductor ranging from sizes of 4/0 to 2000 mcm) around a electrical vault to reduce step and/or touch voltage within the effective area in the vault. Do you guys have any experience on this? or any web site referances on this topic...
Familiar with this relay?
If so, it states if the Watt-Var switch is "ON".
It will indicate a balanced 3-phase tripping under reverse magnetizing current and at the same time handle phase unbalanced condition.
Will this see a line to ground fault?
Thanks for the help...............
On a delta connection and one of the legs fails and creates an open delta. What causes the voltage fluctuation?
Is the fluctuation of voltage caused by the variants of the load (ie: load dependent?).
