Page 35 6F2T0207 (0.01) Overcurrent protection (OC) The phase overcurrent (OC) protection is the major protection function and has both time characteristic and directional elements. Four stages (elements) are available in the OC protection. The user can select various features using the scheme switches provided. The elements are named OC1, OC2, OC3, and OC4;...
Page 36 6F2T0207 (0.01) Relay polarity 2.1.1 The user can choose either non-directional OC or directional OC for each OC stage. In addition, the user can further select either the forward or the reverse direction for each of the directional OC elements selected. Characteristic of non-directional OC The characteristic of the non-directional type OC is a circle that has a center at the origin.

Page 39 6F2T0207 (0.01) Characteristic of directional OC in the reverse direction (iii) The reverse characteristic is a mirror image of the forward characteristic. The setting and the scheme switch, as well as the setting of the directional OC element in the forward direction, provides the setting of the directional OC element in the reverse direction: for example, Reverse is set for the scheme switch [OC1-Dir] when the direction of the OC on stage 1 is considered.
Page 40 6F2T0207 (0.01) Inverse time and definite time delay characteristic 2.1.2 The OC element monitors the currents; when one of the currents is beyond the threshold of operation, the OC element will operate within a period that is defined by the time characteristic feature.
Page 41 6F2T0207 (0.01) When definite time resetting is selected with the operation of the inverse time OC selection and the reset time set to zero (instantaneous), no intentional delay is added for the resetting: that is, when the energizing current falls below the reset threshold of the OC element, the OC element returns to its reset condition.
Page 42 6F2T0207 (0.01) DT characteristic (ii) The operate time in the DT characteristic will be a constant time and is not affected by the level of current. The reset time is set to zero so that resetting is performed immediately. The user can set the operate time using a setting;...

In the IDMT, the user can also program the characteristic using time-multiplier-setting (TMS) for the required operate time. For example, when the IEC characteristic is selected, the user can set the TMS value using the setting [OC1-TMS-IEC] (incidentally, the default value for the TMS is 1.00).
Page 44 6F2T0207 (0.01) Time characteristic The user should set DT for the scheme switches [OC1-Timer]. The value of the required operate time is set for the setting [TOC1] in the range 0.00–300.00s. Instantaneous activation The operate time of the instantaneous characteristic is achieved by setting zero for the [TOC1], but the instantaneous one can also obtained when the logic signal ‘1(High)’...

Page 49 6F2T0207 (0.01) Miscellaneous functions 2.1.6 Trip mode Every OC element has a selectable tripping mode; the mode is selected using a scheme switch. For the OC1 element, for example, a scheme switch [OC1-OPMD] is provided. When a trip is required for any faults that are detected, 3POR (a fault occurs in one or more phases) is set for the scheme switch [OC1-OPMD].

Page 60 6F2T0207 (0.01) Earth fault protection (EF) The earth fault protection (EF) function has four stages (elements); each element can have either a directional characteristic or non-directional characteristic. To simplify the description, only EF1 is discussed but is applicable to the other EFs; hence, read the expression for EF1 as EF2, EF3 and EF4 at each EF stage unless a special explanation or instruction has been provided.
Page 61 6F2T0207 (0.01) Relay polarity 2.2.1 The user can choose either non-directional EF or directional EF for each EF stage.

Page 67 6F2T0207 (0.01) Figure 2.2-4 Inverse-time-reset characteristics curves Figure 2.2-5 illustrates that an integrating value will be influenced dependent on the DEP or DEF setting. An energized quantity (I), where I is greater than a threshold setting [EF1], will make an integrating value, which can determine how the element operates. If the energized quantity (I) falls below the threshold setting [EF1], the element operation will return to its reset stage after the time t(I) calculated in Equation (2.2-2).
Page 68 6F2T0207 (0.01) Reset time of DT (vi) In the DT characteristic, the reset time is designed to be instant. Summary of EF operation (vii) Table 2.2-3 shows a summary for EF operation. Note that DEF will be set unconditionally in IEC-NI, VI, EI and UK-LTI characteristics (†).
Page 69 6F2T0207 (0.01) Miscellaneous functions 2.2.5 Blocking EF by ICD The operation of each EF element can be blocked if the ICD function detects a second harmonic current caused by the magnetizing inrush current phenomenon when a transformer is energized. For example, for the EF1 element, the scheme switch [EF1-2fBlk] is provided, and Block should be set when the user wishes to block the EF1 element when the second harmonic associated with magnetizing inrush is present.

POP, UOP and BOP can issue a three-phase trip (3P) command. The POP, UOP and BOP schemes also permit to operate the function of autoreclose (ARC†).
Page 78 6F2T0207 (0.01) Permissive overreach protection (POP) 2.3.1 DEFCAR sends a trip permission signal in POP; and POP does not send a trip permission signal for non-internal fault. Figure 2.3-1 shows POP scheme logic. The elements of OCD are used to select a phase that should be tripped in CB. When POP receives a trip permission signal, POP issues a trip signal on condition that DEFCF has operated.

Page 155 6F2T0207 (0.01) CBF operation and its elements 2.12.1 The operation of CBF is initiated by the operation of OCCBF and EFCBF, which monitors fault current after the issuance of a trip command by other protection functions. OCCBF or EFCBF monitor the fault current so that the CBF feature can determine the failure of the CB to operate. For CBF, the respective phase currents in three-phase system are monitored by the OCCBF- A, OCCBF-B and OCCBF-C elements, while the zero-sequence current is monitored by the EFCBF element.

Because load current is usually present, the OCCBF and EFCBF settings should be account for between 10% and 200% of the rated current. The time settings [TCBF-RE] and [TCBF-TP] are determined in relation to the opening time of the target CB and the reset time of the OCCBF or EFCBF elements (see Toc and Tcb in Figure 2.12-1).

As described earlier, the VT failure is grouped into the VTF1 criterion (VTF1_DETECT) and the VTF2 criterion (VTF2_DETECT). When we consider the VTF1 criterion, the upper logic in Figure 2.20-1 is used; whereas we consider the VTF2 criterion, lower one is used.

Unsuccessful synchronization check If the injected signal “DPSY01_OEC_RCV” persists for longer than a pre-determined time, the check logic determines that synchronization has not occurred; hence, the check logic can issue a failure signal for the DPSY01 function. Consequently, the DPSY01 function abandons the attempt to close the CB due to the failure in the synchronization process.

Page 751 6F2T0207 (0.01) Fault duration time IED automatically measures and records the duration of fault occurrence (fault duration time). Figure 8.1-1 shows the “Fault duration time” that IED can automatically measure and “Actual fault duration time”. Though the period of actual fault duration time is from fault occurrence until fault clearance by CB opened, the period that IED can measure is only from any relay operation by fault occurrence until the CB trip signal generation.
Page 752 6F2T0207 (0.01) Start and stop of measuring the fault duration time is processed by the logic illustrated in Figure 8.1-1. Measuring is started and stopped by the generation of PLC connecting points [FDT_PU_Trig] and [FDT_DO_Trig]. The “GEN TRIP” signal is assigned to [FDT_DO_Trig] as default, and no default signal is assigned to [FDT_PU_Trig].
Page 753 6F2T0207 (0.01) As mentioned above, the fault duration time measured by IED is shorter than the actual fault duration time, because it does not include relay operating time, BO contact closing time and CB opening time. For this reason, LCD screen shall display a fault duration time, which is complemented with relay operating time, BO contact closing time and CB opening time.
