Some customers prefer very low currents to display as zero, while others prefer the current be displayed even when the value reflects noise rather than the actual signal. The T60 applies a cut- off value to the magnitudes and angles of the measured currents.

Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user-programma- ble pushbuttons to clear specific records are typical applications for these commands. Since the T60 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
SERIAL PORTS The T60 is equipped with up to two independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM2 port be used for either RS485 or RRTD communications.

TIMEOUT: 120 s The T60 supports the Distributed Network Protocol (DNP) version 3.0. The T60 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the T60 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the T60 at one time.
Page 152
DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the T60 will be returned as 72). These settings are useful when analog input values must be adjusted to fit within cer- tain ranges in DNP masters.

The T60 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported over two protocol stacks: TCP/IP over ethernet and TP4/CLNP (OSI) over ethernet. The T60 operates as an IEC 61850 server. The Remote inputs and outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.

DESTINATION MAC address; the least significant bit of the first byte must be set. In T60 releases previous to 5.0x, the destination Ethernet MAC address was determined automatically by taking the sending MAC address (that is, the unique, local MAC address of the T60) and setting the multicast bit.
Page 157
The T60 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station components.

CTs and tapped relay windings with some combination of CT connections. The T60 simplifies these configuration issues. All CTs at the transformer are connected wye (polarity markings pointing away from the transformer). User-entered settings in the relay characterizing the transformer being protected and allow the relay to automatically perform all necessary magnitude, phase angle, and zero-sequence compensation.
Page 216
The reason the source phase sequence must be stated when describing the winding phase relationships is that these rela- tionships change when the phase sequence changes. The example shown below shows why this happens, using a trans- former described in IEC nomenclature as a type “Yd1” or in GE Multilin nomenclature as a “Y/d30.” 5-92...
Page 217
Note that the delta winding currents leads the wye winding currents by 30°, (which is a type Yd11 in IEC nomenclature and a type Y/d330 in GE Multilin nomenclature) which is in disagreement with the transformer nameplate. This is because the physical connections and hence the equations used to calculate current for the delta winding have not changed.
Page 218
CTs or tapped relay windings were used to minimize this error. The T60 automatically corrects for CT mismatch errors. All currents are magnitude compensated to be in units of the CTs of one winding before the calculation of differential and restraint quantities.
Page 219
The T60 performs this phase angle compensation and zero sequence removal automatically, based on the settings entered for the transformer. All CTs are connected Wye (polarity markings pointing away from the transformer). All currents are phase and zero sequence compensated internally before the calculation of differential and restraint quantities.

Synchrophasors from different locations within the power system are networked to a central location. The T60 offers PMU features over two communication standards, IEC61850-9-5 and C37.118. The complete Synchropha- sor implementation for Firmware version 7.0 is shown in the figure below.
Page 240
Precise time input to the relay from the international time standard, via either IRIG-B or PTP, is vital for correct syn- chrophasor measurement and reporting. For IRIG-B, a DC level shift IRIG-B receiver must be used for the phasor measurement unit to output proper synchrophasor values. NOTE 5-116 T60 Transformer Protection System GE Multilin...

CONFIGURATION EXAMPLE: CFG-2 BASED CONFIGURATION (USING IEC61850-90-5) The T60 is expected to send the CFG-2 file (IEEE C37.118 config. file) upon request from the upstream synchrophasor devices (e.g., P30) without stopping R-SV multicasting, see figure below. The primary domain controller (PDC) does not need to use a stop/start data stream command if the UR protocol is set to IEC61850-90-5 prior to requesting the configura- tion via CFG-2 (IEEE C37.118 config.

The T60 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the T60 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the T60 to have an IP address to establish communications. These addresses are located in the ...
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the T60 to provide access to as many 128 digital status points and associated time- stamps and quality flags. The data content must be configured before the data can be used. GGIO1 provides digital status points for access by clients.
A limited number of measured analog values are available through the MMXU logical nodes. Each MMXU logical node provides data from a T60 current and voltage source. There is one MMXU available for each con- figurable source (programmed in the ...
Page 640
The protection elements listed above contain start (pickup) and operate flags. For example, the start flag for PIOC1 is PIOC1.ST.Str.general. The operate flag for PIOC1 is PIOC1.ST.Op.general. For the T60 protection elements, these flags take their values from the pickup and operate FlexLogic operands for the corresponding element.
C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the T60. This name is composed of two parts: the IED name setting and the logical device instance. The complete logical device name is the combination of the two character strings programmed in the settings.
A built-in TCP/IP connection timeout of two minutes is employed by the T60 to detect ‘dead’ connections. If there is no data traffic on a TCP connection for greater than two minutes, the connection will be aborted by the T60. This frees up the con- nection to be used by other clients.
MAC address for GSSE messages. If GSSE DESTINATION MAC ADDRESS a valid multicast Ethernet MAC address is not entered (for example, 00 00 00 00 00 00), the T60 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 644
The T60 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station components.
Page 645
REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic equations or other settings. The T60 must be rebooted (control power removed and re-applied) before these settings take effect. The value of remote input 1 (Boolean on or off) in the receiving device will be determined by the GGIO1.ST.Ind1.stVal value in the sending device.
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the T60 is configured to use an automated multicast MAC scheme. If the T60 destination MAC address setting is not a valid multicast address (that is, the least significant bit of the first byte is not set), the address used as the destina- tion MAC will be the same as the local MAC address, but with the multicast bit set.
An ICD file is generated for the T60 by the EnerVista UR Setup software that describe the capabilities of the IED. The ICD file is then imported into a system configurator along with other ICD files for other IEDs (from GE or other ven- dors) for system configuration.
Transmission GOOSE dataset may be added or deleted, or prefixes of some logical nodes may be changed. While all new configurations will be mapped to the T60 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Although configurable transmission GOOSE can also be created and altered by some third-party system con- figurators, we recommend configuring transmission GOOSE for GE Multilin IEDs before creating the ICD, and strictly within EnerVista UR Setup software or the front panel display (access through the Settings > Product Setup > Com- munications >...

Furthermore, it defines the capabilities of an IED in terms of communication services offered and, together with its LNType, instantiated data (DO) and its default or configuration values.

The EnerVista UR Setup will prompt to save the file. Select the file path and enter the name for the ICD file, then click OK to generate the file. The time to create an ICD file from the offline T60 settings file is typically much quicker than create an ICD file directly from the relay.

The software will open the SCD file and then prompt the user to save a UR-series settings file. Select a location and name for the URS (UR-series relay settings) file. If there is more than one GE Multilin IED defined in the SCD file, the software prompt the user to save a UR-series set- tings file for each IED.
