Page 13: Ur Overview
This new generation of equipment is easily incorporated into automation systems, at both the station and enterprise levels. The GE Multilin Uni- versal Relay (UR) series meets these goals.
Page 14 The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the logic program (FlexLogic equation), and then sets each output to the appropriate state in an output status table. Any result- ing task execution is priority interrupt-driven. Figure 1–3: UR-SERIES SCAN OPERATION T35 Transformer Protection System GE Multilin...

Page 18 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 19 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 20: Using The Quick Connect Feature
Before starting, verify that the serial cable is properly connected from the 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). See the Software Installation section if not already installed.

Page 215 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.

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 513: Configuring Iec 61850 Settings
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.
Page 514: 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 >...
