Learn about Understanding Protection Relays and how they prevent damage to electrical systems due to overcurrent and faults.
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.
Among the various possible methods used to achieve correct relay co-ordination are those using either time or overcurrent, or a combination of both.
The protection features include Delta thermal shutdown, overcurrent, overtemperature, ESD, and integrated drain-to-gate clamping for
