MENU TEXT
Setting to enable or disable the third stage definite time sensitive earth fault element.
ISEF>3 Direction
This setting determines the direction of measurement for the third stage element.
ISEF>3 Current
Pick-up setting for the third stage sensitive earth fault element.
ISEF>3 Delay
Setting for the operating time delay for third stage sensitive earth fault element.
ISEF>4 Status
Setting to enable or disable the fourth stage definite time sensitive earth fault element.
ISEF>4 Direction
This setting determines the direction of measurement for the fourth stage element.
ISEF>4 Current
Pick-up setting for the fourth stage sensitive earth fault element.
ISEF>4 Delay
Setting for the operating time delay for fourth stage sensitive earth fault element.
ISEF> Blocking
Logic Settings that determine whether blocking signals from VT supervision affect certain earth fault overcurrent stages.
VTS Block - only affects sensitive earth fault protection. With the relevant bit set to 1, operation of the Voltage Transformer Supervision (VTS),
will block the stage. When set to 0, the stage will revert to Non-directional upon operation of the VTS.
ISEF DIRECTIONAL
ISEF> Char Angle
Setting for the relay characteristic angle used for the directional decision.
ISEF> VNpol Set
Setting for the minimum zero sequence voltage polarizing quantity required for directional decision.
Wattmetric SEF
PN> Setting
Setting for the threshold for the wattmetric component of zero sequence power. The power calculation is as follows:
The PN> setting corresponds to:
Vres x Ires x Cos (φ – φc) = 9 x Vo x Io x Cos (φ– φc)
Where; φ = Angle between the Polarizing Voltage (-Vres) and the Residual Current
φc = Relay Characteristic Angle (RCA) Setting (ISEF> Char Angle)
Vres = Residual Voltage
Ires = Residual Current
Vo = Zero Sequence Voltage
Io = Zero Sequence Current
