After ensuring the minimum requirements for using EnerVista UR Setup are met (see previous section), use the following procedure to install the EnerVista UR Setup from the enclosed GE EnerVista CD. Insert the GE EnerVista CD into your CD-ROM drive.
Page 20: Configuring The T60 For Software Access
The user can connect remotely to the T60 through the rear RS485 port or the rear Ethernet port with a PC running the EnerVista UR Setup software. The T60 can also be accessed locally with a computer through the front panel RS232 port or the rear Ethernet port using the Quick Connect feature. T60 Transformer Protection System GE Multilin...
Page 21 RS232 port. A computer with an RS232 port and a serial cable is required. To use the RS485 port at the back of the relay, a GE Multilin F485 converter (or compatible RS232-to-RS485 converter) is required. See the F485 instruction manual for details.
Page 22 UR device must be on the same subnet. Verify that the latest version of the EnerVista UR Setup software is installed (available from the GE EnerVista CD or online from http://www.gedigitalenergy.com/multilin). See the Software Installation section for installation details.
Page 23: Using The Quick Connect Feature
Before starting, verify that the serial cable is properly connected from the laptop computer to the front panel RS232 port with a straight-through 9-pin to 9-pin RS232 cable. Verify that the latest version of the EnerVista UR Setup software is installed (available from the GE EnerVista CD or online from http://www.gedigitalenergy.com/multilin).

The injected frequency should smoothly ramp through the set threshold, with the ramp starting frequency sufficiently out- side the threshold so the relay becomes conditioned to the trend before operation.

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.

It can also import a system SCL file (SCD) to set communication configuration parame- ters (that is, required addresses, reception GOOSE datasets, IDs of incoming GOOSE datasets, etc.) for the IED. The IED configurator functionality is implemented in the GE Multilin EnerVista UR Setup software. C.5.2 CONFIGURING IEC 61850 SETTINGS Before creating an ICD file, the user can customize the IEC 61850 related settings for the IED.

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 663 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. There should be only one IED section in an ICD since it only describes one IED. GE Multilin T60 Transformer Protection System C-15...

C.5.5 ABOUT SCD FILES System configuration is performed in the system configurator. While many vendors (including GE Multilin) are working their own system configuration tools, there are some system configurators available in the market (for example, Siemens DIGSI version 4.6 or above and ASE Visual SCL Beta 0.12).
Page 667 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 C–7: SCD FILE STRUCTURE, SUBSTATION NODE GE Multilin T60 Transformer Protection System C-19...

Page 669: 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. Select the saved SCD file and click Open. GE Multilin T60 Transformer Protection System C-21...
Page 670 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.
