Ungrounded: There is no intentional ground applied to the system-however it's grounded through natural capacitance. This decreases the current at the fault and limits voltage across the arc at the fault to. Long term cost reduction (TCO) for trainings and maintenance by reduce variety of relays A fast and selective arc fault mitigation for air-insulated LV & MV switchgear and Relion protection and control relays and sensor technology protect staff and plant facilities for many years. Protective Relay Definition: A protective relay is an automatic device that senses abnormal conditions in electrical circuits and triggers actions to isolate faults.
