●●● Restricted Earth Fault (REF) Protection Restricted Earth Fault (REF) protection is a highly sensitive unit protection scheme used to detect internal earth faults within the restricted zone of a transformer. It offers fast, selective, and reliable protection to minimize equipment damage and improve system stability. ● What Is REF Protection? REF monitors the balance between the summed phase currents and the neutral current. Any imbalance within the protected zone indicates an internal earth f
