6 F 2 S 0 8 5 7 2.2 Current Differential Protection 2.2.1 Differential Scheme Current differential protection DIFT provides an overall transformer protection deriving phase current from each transformer winding, calculating the differential current on a per phase basis and detecting phase-to-phase and phase-to-earth faults. The current differential protection is based on Kirchhoff’s first law that the vector summation of all currents flowing into a protected zone must be zero. Figure 2.2.1.
6 F 2 S 0 8 5 7 “2PAND” is recommended for a transformer with small or midium capacity whose second harmonic component in inrush current is genarally higher than that of transformer with large capacity. This mode is applicable if [Phase matching] is set to “Beta”. Protection by DIF and HOC can perform instantaneous three-phase tripping of up to five breakers. Any of the five breaker tripping signals DIFT-1 to DIFT-5 are enabled or disabled by the scheme switch [DIF1] to [DIF5] settings.
6 F 2 S 0 8 5 7 Display mode following differential tripping Following a trip output, GRT100 can display either the operating phase or the faulted phase according to the user’s requirements as shown in Table 2.2.1.1. The operating phase or faulted phase display is selectable by a setting in the Record menu. Table 2.2.1.

6 F 2 S 0 8 5 7 2.2.2 Stability for CT Saturation during Through-fault Conditions For current differential protection of transformers, GRT100 has a strong restraint characteristic in the large current region for erroneous differential current due to CT saturation. Further, GRT100 provides a CT saturation countermeasure function.

6 F 2 S 0 8 5 7 2.2.3 Matching of CT Secondary Currents The currents supplied to the differential elements must be matched in phase displacement and amplitude under through-load and through-fault conditions. Generally, it is difficult to completely match the incoming current with the outgoing current for the relay input because the CT ratios at the primary, secondary and tertiary sides of a transformer are not matched in terms of the CT ratio, phase angle and cancelling of zero-sequence current.

6 F 2 S 0 8 5 7 2.2.3.3 Zero-sequence current elimination In addition to compensating for the phase angle between the primary and secondary currents of the transforemer, also phase angle matching prevents unnecessary operation due to zero-sequence current during an external earth fault, such as in the following cases. Case 1: When an external fault occurs at the star-connected side of the transformer shown in Figure 2.2.3.
6 F 2 S 0 8 5 7 In α-method phase matching, since the DIFT provides a function to eliminate the zero-sequence current by software, the DIFT is insensitive to the fault described. In β-method phase matching, however, since the zero-sequence current is not eliminated because of Star connection on the Delta-winding side, the DIFT may operate unnecessary. In case the GRT100 is applied to a transformer with in-zone earthing transformer, the [Phase matching] = “Alpha” setting is recommended. 2.2.3.
6 F 2 S 0 8 5 7 2.2.4 Connection between CT Secondary Circuit and the GRT100 GRT100 is provided with 2 or 3 three-phase current input terminals depending on the relay model.

6 F 2 S 0 8 5 7 3.3 Automatic Supervision 3.3.1 Basic Concept of Supervision Though the protection system is in a non-operating state under normal conditions, it is waiting for a power system fault to occur at any time and must operate for the fault without fail. Therefore, the automatic supervision function, which checks the health of the protection system during normal operation by itself, plays an important role.
6 F 2 S 0 8 5 7 DC Supply monitoring The secondary voltage level of the built-in DC/DC converter is monitored and checked that the DC voltage is within a prescribed range. 3.3.3 PLC Data and IEC61850 Mapping Data Monitoring If there is a failure in PLC data and IEC61850 mapping data, the function may be stopped. Therefore, the PLC data and IEC61850 mapping data are monitored and an alarm of "PLC stop" or "MAP stop" is issued if any failure detected. 3.3.

If the voltage input is not provided, then the positive sequence current of the primary winding is used as a reference phase angle. 3.4.
6 F 2 S 0 8 5 7 The number of records stored depends on the post-fault recording time. The approximate relationship between the post-fault recording time and the number of records stored is shown in Table 3.4.2. Note: If the recording time setting is changed, all previously recorded data is deleted.

6 F 2 S 0 8 5 7 CT requirement The GRT100 does not require the use of dedicated CTs nor the use of CTs with an identical ratio. The GRT100 can share the CTs with other protections and the different ratios are adjusted by setting. The general CT requirements are set for the through-fault stability which comes up when any CTs saturate under very large through-fault currents.

6 F 2 S 0 8 5 7 Implementation of Thermal Model to IEC60255-8 Heating by overload current and cooling by dissipation of an electrical system follow exponential time constants. The thermal characteristics of the electrical system can be shown by equation (1).
6 F 2 S 0 8 5 7 where: IP = prior load current. In fact, the cold curve is simply a special case of the hot curve where prior load current IP = 0, catering for the situation where a cold system is switched on to an immediate overload. Figure N-2 shows a typical thermal profile for a system which initially carries normal load current, and is then subjected to an overload condition until a trip results, before finally cooling to ambient temperature.
