It has three phasesegregated differential elements (DIF-Stage ), each with a dual-slope, percentage differential characteristic as shown in Figure. GRT00 also provides high-set unrestrained differential elements (DIF-Stage ). 3

For higher level faults, the large current characteristic with increased bias compensates for the effects of CT saturation. Furthermore, GRT00 provides a CT saturation countermeasure function against a very large through-fault current. GRT00 incorporates internal CT ratio and vector compensation, so that the relay requires no interposing CTs. Mixed A/5A inputs for phase currents are available. CT polarities for each three-phase CT can be set flexibly within GRT00 in accordance with external physical connections to each three-phase CT. During periods of transformer energization, the use of a second harmonic restraint method blocks the relay operation. neutral point current, restricted earth fault protection (REF) provides a highly sensitive differential protection for earth faults in a transformer which has a star point directly earthed or low impedance earthed. The REF-DIF element has a dual slope, percentage characteristic as shown in Figure and the independent elements can be applied for each transformer winding.

6 Mixed A/5A inputs for phase and neutral currents are available. CT polarities for each neutral CT can be set flexibly within GRT00 in accordance with external physical connections to each neutral CT. Breaker Failure Protection (CBF) When an overcurrent element remains in operation longer than a pre-determined length of time following the output of a trip signal the associated circuit breaker is judged to have failed and adjacent circuit breakers can be tripped as a back-up measure. can be blocked by a binary input signal. GRT00 provides up to 4 non-directional overcurrent protections (EFIn) with inverse time and definite time for earth faults which can be applied flexibly for each transformer winding, utilizing neutral current values observed. GRT00 also provides up to directional or non-directional overcurrent protections (EF) with inverse time and definite time for earth faults which can be applied flexibly for each transformer winding, utilizing residual current values calculated by phase currents observed. Two independent timers are available, one of which can be used to control the RETRIP of the original circuit breaker(s). The second timer is used to control the back-tripping of adjacent circuit breakers. For high-speed protection, an overcurrent element with high-speed reset time is used to prevent a spurious re-trip or back-trip following a successful trip or re-trip action. Overcurrent Protection (OC / EFIn / EF) GRT00 provides up to directional or non-directional overcurrent protections (OC) with inverse time and definite time for phase faults which can be applied flexibly for each transformer winding. Inverse time overcurrent protection consists of an IDMT (inverse definite minimum time) element. IDMT is available in conformity with the IEC standard which encompasses both the IEC and IEEE/ANSI standard characteristics as shown in Figure 3. Alternatively, a user-configurable curve may be created. The IDMT element has a programmable reset feature, selectable for instantaneous, definite time or dependent time operation. This feature can be used to protect against flashing/intermittent fault conditions, or to grade correctly with electromechanical overcurrent relays. Definite time overcurrent protection is enabled by the instantaneous overcurrent element and pickup-delay timer. Tripping by each element can be disabled by the scheme switches, and overcurrent backup protection Figure 5: Characteristics of inverse time delayed overcurrent element Negative Phase Sequence Overcurrent Protection (OCN) Up to 4 negative phase sequence overcurrent protections (OCN) can be applied flexibly for each 5

7 transformer winding. OCN can be used in applications where certain fault conditions may not be detected by the normal phase and earth overcurrent protections, for example, in the case of a relay applied on the delta side of a delta-star transformer, to detect an earth fault on the star side. Thermal Overload Protection (THM) The thermal overload feature provides protection for cables and other plant against the effects of prolonged operation under excess load conditions. A thermal replica algorithm is applied to create a model for the thermal characteristics of the protected plant. Tripping times depend not only on the level of overload current, but also on the level of prior load current, the thermal replica providing memory of previous conditions. The thermal characteristics of the system are defined by entering settings for full load current and thermal time constant. The GRT00 issues a trip in accordance with the cold and hot curves specified in IEC to prevent the protected system from exceeding its thermal capacity. The cold curve tripping times are applicable when the system is first energized, while the hot curves are relevant when the system has already been carrying some prior load for a period of time. An alarm output is also available to give early warning of high load current, set as a percentage of thermal capacity. Broken Conductor Detection (BCD) GRT00 provides up to 3 broken conductor detections (BCD). Detects unbalance conditions in each transformer winding caused by an open circuited conductor. An unbalance threshold with programmable definite time delay is provided. Inrush Current Detector (ICD) The inrush current detector (ICD) is used to prevent an incorrect operation of the aforementioned OC, EF, OCN and BCD against a magnetizing inrush current during transformer energization. ICD detects second harmonic inrush currents during transformer energization. Overexcitation Protection (VPH) provided. The alarm is definite time delayed whilst the characteristic may be selected as either having a definite time or an inverse time delay as shown in Figure 6. V/Hz VPH-H VPH-L VPH-A 0 TVPHA Figure 6: VPH characteristic Zero Phase Sequence Overvoltage Protection (OVG) Up to 4 zero phase sequence overvoltage protections (OVG) are provided for detection of earth faults in high impedance earthed or isolated systems. OVG can be programmed with definite time delays, and one stage is also available with an inverse delay. The zero sequence voltage may be derived from the phase voltages, or directly measured. Suppression of superimposed 3rd harmonic components of the supply voltage is included. Under/Over Frequency and Rate of Change of Frequency Protection (FRQ) GRT00 provides up to 6 stage frequency protections where over/under frequency protections or rate-of-change-of-frequency protections can be selected flexibly. VPH-HT TVPHH VPH-L: VPH-H: VPH-LT: VPH-HT: TVPHH: VPH-A: TVPHA: VPH-LT These protections provide independent frequency protection stages. The over/under frequency protection is programmable for either under- or over-frequency operation, and each has an associated delay timer. The rate-of-change-of-frequency protection calculates the gradient of frequency change (df/dt). Low level i.e. Pick up level High level i.e. Definite time tripping level Operate time at low level Operate time at high level Definite time delay at high level Alarm level Definite time delay for alarm sec (log T) Alarms and tripping for overexcitation, based on a measurement of the voltage/frequency ratio are 6
