Stage 2 of the sub-harmonic stator ground protection has operated
Ground over current element of the sub-harmonic stator ground protection
has picked up
Ground over current element of the sub-harmonic stator ground protection
has dropped out
Ground over current element of the sub-harmonic stator ground protection
has operated
Sub-harmonic stator ground module trouble has picked up
Sub-harmonic stator ground module trouble has dropped out

Source 1 disturbance detector has operated
Source 2 disturbance detector has operated
Source 3 disturbance detector has operated
Source 4 disturbance detector has operated
Source 5 disturbance detector has operated
Source 6 disturbance detector has operated
Source 1 VT fuse failure detector has operated
Source 1 VT fuse failure detector has dropped out
Source 1 has lost voltage signals (V2 below 10% and V1 below 5%
of nominal)
Source 1 VT neutral wire open detected.When the VT is connected in Delta,
this function should not be enabled because there is no neutral wire for Delta
connected VT.
