and reverse direction Min Reverse Operate Current), which is applied in current
magnitude threshold supervision, and which is further defined with setting
Operating Quantity. Available options are "Adaptive", "Amplitude" and
"Resistive".
When the above four conditions are satisfied, the MFAPSDE_St output is activated
once Start Delay Time has elapsed. MFAPSDE_Oper output activates after Operate
delay time has elapsed. Reset timer is started if any of the above four conditions is not
valid. In case the fault is transient and self-extinguishing, MFAPSDE_St output stays
active until the elapse of reset timer (Reset Delay Time ). After the MFAPSDE_Oper
output activation, MFAPSDE_St and MFAPSDE_Oper outputs are immediately
reset, if any of the above four conditions are not valid. In addition, the
MFAPSDE_OpFw and MFAPSDE_OpRe outputs are activated based on the fault
direction.
The start and operate of fault are also available as GOOSE outputs MFAPSDE_St and
MFAPSDE_Oper.
Output MFAPSDE_Oper is configured to LED 8 of the SiM8F
module. The LED turns ON when this signal becomes high. The LED
color depends on setting Directional mode of the MFAPSDE
function. The LED is green for forward setting and red for reverse
setting.
If the detection of temporary earth faults is not desired, the activation
of MFAPSDE_St output may be delayed with the Start Delay Time
setting. The same setting can also be used to avoid restarting of the
function during long lasting post-fault oscillations, if time constants
of post-fault oscillations are very long (network losses and thus Low
damping).
