Description
09	00	CONFIGURATION
This column contains all the general configuration options
09	01	Restore Defaults	No Operation	0 = No Operation, 1 = All Settings, 2 = Setting Group 1, 3 = Setting Group 2, 4 = Setting Group 3, 5 = Setting Group 4
Setting to restore a setting group to factory default settings. To restore the default values to the settings in any Group settings, set the ’restore defaults’ cell to the relevant Group number. Alternatively it is possible to set the ’restore defaults’ cell to ’all settings’ to restore the default values to all of the IED’s settings, not just the Group settings. The default settings will initially be placed in the scratchpad and will only be used by the IED after they have been confirmed by the user. Note: Restoring defaults to all settings includes the rear communication port settings, which may result in communication via the rear port being disrupted if the new (default) settings do not match those of the master station.

This time delay is set to prevent maloperation due to zone evolution from zone n to zone n-1 by CB operation.
30	32	V Mem Validity	10s	From 0s to 10s step 10ms
The duration of the voltage memory availability after fault detection can be set. When the voltage memory is declared unavailable (e.g. the V Mem Validity set duration has expired, SOTF Mode, no healthy network to record memory voltage), other polarizing quantities can be considered. These include zero, negative and positive sequence (if voltage is sufficient). Otherwise directional decision is forced to forward.
30	33	Earth I Detect.	0.05*I1	0I1 to 0.1I1 step 0.01*I1
The residual current threshold (Earth I Detect.) is used by the conventional algorithm to detect earth faults.

Distance Protection Schemes

Col	Row	Courier Text	Default Setting	Available Setting
Description
31	00	GROUP 1: DISTANCE SCHEMES
GROUP1: Distance Schemes
31	01	Program Mode	Standard Scheme	Standard Scheme Open Scheme
The ’Program Mode’ cell is used to select the standard program mode or open program mode. When Standard program mode is set, a standard basis scheme is selectable. When a scheme is not covered in the Standard modes, the open programming mode can be selected. The user then has the facility to decide which distance relay zone is to be used to program the signalling channel, and what type of aided scheme runs when the channel is received. The signal send zone options, and the aided scheme options on channel receipt are settable.
31	02	Standard Mode	Basic + Z1X	Basic + Z1X, P.O.P Z1, P.O.P Z2, P.U.P Z2, P.U.P FWD, B.O.P Z1, B.O.P Z2
The following schemes are available when the Standard program mode is selected: – Basic + Zone 1 extended (see section P44x/EN AP), – Permissive Underreach Transfer Trip Schemes PUP Z2 and PUP Fwd, – Permissive Overreach Transfer Trip Schemes POP Z2 and POP Z1; – Blocking Schemes BOP Z2 and BOP Z1. The PUP, POP and BOP schemes are detailed in section P44x/EN AP
31	03	Fault Type	Both enabled	Phase to Ground, Phase to Phase, Both enabled.
Fault type setting
31	04	Trip Mode	Force 3 poles	Force 3 poles, 1P Z1 & CR, 1P Z1 Z2 & CR
Sets the tripping mode: 1-pole trip or 3-pole trip.
31	05	Sig Send Zone	None	None, CsZ1, CsZ2, CsZ4.
The ’Signal Send Zone’ option is available when an open scheme program mode is set. The user can decide which distance relay zone is used to send the signalling channel: – CsZ1 or CsZ2 (’Carrier send’ from Z1 or Z2): when a fault is detected in zone 1, or zone 2, the ’Carrier Send’ is emitted from this zone to the relay. These settings are used to configure a permissive scheme. – CsZ4 (’Carrier send’ from Z4) when a fault is detected in zone 4 (reverse). This setting can be used to configure a blocking scheme. See section decision logic in the section P44x/EN AP.
31	06	DistCR	None	None, PermZ1, PermZ2, PermFWD, BlkZ1, BlkZ2.
The ’Distance Carrier received’ option is available when an open scheme program mode is set. Aided scheme options on CR receipt: – Select ’None’ to configure a basic scheme, – Select ’PermZ1’ or ’PermZ2’ to configure a permissive scheme where Zone 1 or Zone 2 can only trip (without waiting tZ1 or tZ2 timeout) if a signal is received, – Select ’BlkZ1’ or ’BlkZ2’ to configure a blocking scheme where Zone 1 or Zone 2 can only trip if a Distance Carrier is NOT received, – Select ’PermFwd’ to configure a permissive scheme where any forward distance zone start will cause an aided trip if a Distance Carrier is received.
31	07	Tp	20ms	From 0s to 1s step 2ms
Time setting
31	08	tReversal Guard	20ms	From 0s to 150ms step 2ms
Where appropriate, the tReversal Guard and ’Aid Dist Delay’ (transmission time in blocking scheme) time-delays (in the case of a blocking scheme covering the transmission time) settings will appear in the relay menu. Further customising of distance schemes can be achieved using the Programmable Scheme Logic to condition send and receive logic.
31	09	Unblocking Logic	None	None, Loss of Guard, Loss of Carrier.
Three modes of unblocking logic are available for use with permissive schemes (blocking schemes are excluded): – None (basic mode), – Loss of Guard mode, – Loss of carrier mode. See section P44x/EN AP for details.
31	0A	SOTF/TOR Mode	100000000110000(bin)	Bit 00=TOR Z1 enabled Bit 01=TOR Z2 enabled Bit 02=TOR Z3 enabled Bit 03=TOR All Zones Bit 04=TOR Dist. Scheme Bit 05=SOTF All Zones Bit 06=SOTF Lev. Detect. Bit 07=SOTF Z1 enabled Bit 08=SOTF Z2 enabled Bit 09=SOTF Z3 enabled Bit 0A=SOTF Z1 + Rev en. Bit 0B=SOTF Z2 + Rev en. Bit 0C=SOTF Dist. Scheme Bit 0D=SOTF Disable Bit 0E=SOTF I>3 enabled
Sets individual protection zones to enable or disable the TOR / SOTF protection. Setting the relevant bit to 1 will enable TOR / SOTF for the selected zone, setting bits to 0 will disable TOR / SOTF for the selected zone: – TOR (or SOTF) Zi enabled: TOR or SOTF logic enabled in case of fault in zone i, – TOR (or SOTF) All Zones: TOR or SOTF logic enabled for all zones, – TOR (or SOTF) Dist. Scheme: TOR or SOTF logic enabled for aided trip zones, – SOTF I>3 enabled: TOR and SOTF initiated after detection by I>3 overcurrent, – SOTF Lev. Detect.: SOTF initiated by level detectors. See SOTF / TOR section P44x/EN AP for TOR-SOFT logic and SOFT-TOR trip logic.
31	0B	SOTF Delay	110s	10s to 3600s step 1s
The Switch On To Fault (SOTF) protection (high speed clearance of any detected fault immediately following manual closure of the circuit breaker) and Trip On Reclose (TOR) protection (high speed clearance of any fault detected immediately following autoreclosure of the circuit breaker). It is possible to set the time-delay to trip when, for example, the relay has detected a fault that is still present on a feeder after energising.

Description
32	00	GROUP 1: POWER- SWING

32	01	Delta R	0.5Ω	0 to 400/I1 Ω step 0.01/I1 Ω
Power swing detection Resistive band which surrounds phase fault trip characteristic (see section P44x/EN AP, section 4.1). Typically, the ΔR and ΔX band settings are both set between 10 – 30% of R3Ph. This gives a secondary impedance between 0.6 and 1.8Ω. For convenience, 1.0Ω could be set. The width of the power swing band is calculated as follows: ΔR = 1.3 × tan(π × Δf × Δt) × RLOAD Assuming that the load corresponds to 60° angles between sources and if the resistive reach is set so that Rlim = RLOAD/2, the following is obtained: ΔR = 0.032 × Δf × RLOAD To ensure that a power swing frequency of 5Hz is detected, the following is obtained: ΔR = 0.16 × RLOAD Where: ΔR: width of the power swing detection band Δf: power swing frequency (fA – fB) Rlim resistive reach of the starting characteristic (=R3ph-R4ph) Z: network impedance corresponding to the sum of the reverse (Z4) and forward (Z3) impedances

Flexible – A local time zone adjustment can be defined using the LocalTime offset setting and each interface can be assigned to the UTC zone or local time zone with the exception of the local interfaces which will always be in the local time zone and IEC 61850/SNTP which will always be in the UTC zone.
