DGFD = Directional ground fault detection
IEF = Intermittent ground (earth) fault protection
Dir = Directional Time Overcurrent Protection (67 and 67N Elements)
V, f, P = Voltage protection, frequency protection, power protection
1) for isolated/compensated networks, only for sensitive ground current transformer if 7th digit = 2, 6
2) only for non-sensitive ground current transformer if 7th digit = 1, 5, 7
Automatic Reclosing (79) / Fault Locator
1) Synchrocheck (no asynchronous switching), one function group, available only for 7SJ623, 7SJ624, 7SJ625
and 7SJ626
