When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond- ing connection password. If the connection is to the back of the T60, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password must be used.

DEFAULT MESSAGE TIMEOUT: If the keypad is inactive for a period of time, the relay automatically reverts to a default message. The inactivity time is modified via this setting to ensure messages remain on the screen long enough during programming or reading of actual values. 5-12 T60 Transformer Protection System GE Multilin...
Page 145 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.
Page 146: Clear Relay Records
Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable 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.
Page 147: Communications
SERIAL PORTS The T60 is equipped with up to three independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM1 port type is selected when ordering: either an Ethernet or RS485 port.
Page 148 If the RS485 COM2 port is used for an RRTD, then there must not be any other devices connected in the daisy-chain for any other purpose. The port is strictly dedicated to RRTD usage when is selected as “RRTD”. RS485 COM2 USAGE Power must be cycled to the T60 for changes to the setting to take effect. RS485 COM2 USAGE NOTE...
Page 149 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each T60 must have a unique address from 1 to 254. Address 0 is the broadcast address which all Modbus slave devices listen to.

Page 151 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.

Page 154 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.
Page 155 IEC 61850 GSSE application ID name string sent as part of each GSSE message. This GSSE ID string identifies the GSSE message to the receiving device. In T60 releases previous to 5.0x, this name string was repre- sented by the setting.
Page 156 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.

To set up a T60 to receive a configurable GOOSE dataset that contains two IEC 61850 single point status indications, the following dataset items can be selected (for example, for configurable GOOSE dataset 1): “GGIO3.ST.Ind1.stVal” and “GGIO3.ST.Ind2.stVal”.

Page 161 The GGIO2 control configuration settings are used to set the control model for each input. The available choices are “0” (status only), “1” (direct control), and “2” (SBO with normal security). The GGIO2 control points are used to control the T60 virtual inputs.
Page 162 GGIO4. When this value is NUMBER OF ANALOG POINTS changed, the T60 must be rebooted in order to allow the GGIO4 logical node to be re-instantiated and contain the newly configured number of analog points.
Page 163 GGIO1 (binary status values). The settings allow the selection of FlexInteger™ values for each GGIO5 integer value point. It is intended that clients use GGIO5 to access generic integer values from the T60. Additional settings are provided to allow the selection of the number of integer values available in GGIO5 (1 to 16), and to assign FlexInteger™ values to the GGIO5 integer inputs.
Page 164 Since GSSE/GOOSE messages are multicast Ethernet by specification, they will not usually be forwarded by net- work routers. However, GOOSE messages may be fowarded by routers if the router has been configured for VLAN NOTE functionality. 5-32 T60 Transformer Protection System GE Multilin...

Page 207 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 208 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.” 5-76...
Page 209 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 210 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 211 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.

Page 561: C.1.1 Introduction
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 menu.

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.
Page 563: C.2.6 Mmxu: Analog Measured Values
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 menu).
Page 564 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.
Page 565: C.3.1 Buffered/Unbuffered Reporting
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 settings.
Page 566: C.3.6 Logical Node Name Prefixes
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.
Page 567: C.4.1 Overview
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 568 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 569: C.4.5 Ethernet Mac Address For Gsse/Goose
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.
Page 570: C.4.6 Gsse Id And Goose Id Settings
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.
Page 571: C.5.1 Overview
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.
Page 572: C.5.2 Configuring Iec 61850 Settings
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.
Page 573: C.5.3 About Icd Files
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 >...
Page 574 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.
Page 578 Like ICD files, the Header node identifies the SCD file and its version, and specifies options for the mapping of names to signals. The Substation node describes the substation parameters: Substation PowerSystemResource EquipmentContainer Power Transformer GeneralEquipment EquipmentContainer VoltageLevel Voltage PowerSystemResource Function SubFunction GeneralEquipment 842792A1.CDR Figure 0–7: SCD FILE STRUCTURE, SUBSTATION NODE C-18 T60 Transformer Protection System GE Multilin...

Figure 0–9: SCD FILE STRUCTURE, IED NODE C.5.6 IMPORTING AN SCD FILE WITH ENERVISTA UR SETUP The following procedure describes how to update the T60 with the new configuration from an SCD file with the EnerVista UR Setup software. Right-click anywhere in the files panel and select the Import Contents From SCD File item.
Page 581 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.
