Ground Fault Protection on Ungrounded and High Resistance
... Ungrounded distribution systems are used in industrial installations, due to their ability to provide continuous service with a ground fault on one phase. A single-phase failure to ground does not cause high current to flow, because the current is limited by the capacitance of the other two phases. ...
