Sotf Protection Settings - NR Electric PCS-9611 Instruction Manual

[50GSOTF.3I0_Set] is the current setting of the zero sequence SOTF overcurrent protection;
"t " is the setting [50GSOTF.t_Op], the time setting of the zero sequence SOTF
SOTFROC
overcurrent protection;
[50GSOTF.En] is the logic setting of the zero sequence SOTF overcurrent protection;
[50GSOTF.En1] is the binary signal for enabling the zero sequence SOTF overcurrent
protection;
[50GSOTF.Blk] is the binary signal for blocking the zero sequence SOTF overcurrent
protection;
[SOTF.Opt_Mode] is the setting for selecting the acceleration mode of the SOTF protection;
"t " is the setting [SOTF.t_En], the enabling time setting of the SOTF protection;
EnSOTF
[79.Ready] is used to denote the auto-recloser is ready for operating;
[79.Close_3PSx] (x:1~4) means that the auto-recloser operates;
"SOTF.ManClsCB" denotes the circuit breaker is closed manually (local or remote), f or
example, the circuit breaker is closed by the remote closing command from the SAS or
SCADA, or by pressing the closing button on the control panel.
