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 T35, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password must be used.

Page 147 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 T35 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 148: 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 T35 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Page 149: Communications
0 ms The T35 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 150 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each T35 must have a unique address from 1 to 254. Address 0 is the broadcast address which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in errors will occur.

Page 152 TIMEOUT: 120 s The T35 supports the Distributed Network Protocol (DNP) version 3.0. The T35 can be used as a DNP slave device con- nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the T35 maintains two sets of DNP data change buffers and connection information, two DNP masters can actively communicate with the T35 at one time.
Page 153 DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000 V on the T35 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 5.2 PRODUCT SETUP 5 SETTINGS master can operate a single point for both trip and close, or raise and lower, operations. The T35 can be configured to sup- port paired control points, with each paired control point operating two virtual inputs. The DNP NUMBER OF PAIRED CONTROL setting allows configuration of from 0 to 32 binary output paired controls.
Page 155 The T35 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 T35 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 156 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 T35 releases previous to 5.0x, this name string was repre- sented by the setting.
Page 157 DESTINATION MAC address; the least significant bit of the first byte must be set. In T35 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 T35) and setting the multicast bit.
Page 158 The T35 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 209 CTs and tapped relay windings with some combination of CT connections. The T35 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 210 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 211 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 212 CTs or tapped relay windings were used to minimize this error. The T35 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 213 The T35 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.

TEST MODE FORCING: MESSAGE The T35 provides a test facility to verify the functionality of contact inputs and outputs, some communication channels and the phasor measurement unit (where applicable), using simulated conditions. The test mode is indicated on the relay face- plate by a Test Mode LED indicator.
Page 301: Force Contact Inputs
Following a restart, power up, settings TEST MODE FUNCTION upload, or firmware upgrade, the test mode will remain at the last programmed value. This allows a T35 that has been placed in isolated mode to remain isolated during testing and maintenance activities. On restart, the TEST MODE FORCING setting and the force contact input and force contact output settings all revert to their default states.

Page 455: Iec 61850 Communications
The T35 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the T35 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the T35 to have an IP address to establish communications. These addresses are located in the ...
Page 456: Server Data Organization
C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the T35 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 457: 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 T35 current and voltage source. There is one MMXU available for each con- figurable source (programmed in the ...
Page 458 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 T35 protection elements, these flags take their values from the pickup and operate FlexLogic™ operands for the corresponding element.
Page 459: Server Features And Configuration
C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the T35. 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.
Page 460: Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the T35 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 T35. 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 T35 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 462 The T35 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 463: 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 T35 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 464: Gsse Id And Goose Id Settings
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the T35 is configured to use an automated multicast MAC scheme. If the T35 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 465: Iec 61850 Implementation Via Enervista Ur Setup
An ICD file is generated for the T35 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 466: 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 T35 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.
Page 467: 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 468 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 T35 settings file is typically much quicker than create an ICD file directly from the relay.
Page 472 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 T35 Transformer Protection System GE Multilin...

Page 474: Importing An Scd File With Enervista Ur Setup
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 T35 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 475 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.
