The current value changes from 12.0 kA to 1.5 kA. 1.5 kA is interrupted 3000 times (3000 close/open operations = 6000 – 3000), pushing the breaker maintenance curve from the 50 percent wear level to the 100 percent wear level.

Page 376: Setting Entry Error Messages
Settings Setting Entry Error Messages Setting Entry Error Messages As you enter relay settings, the relay checks the setting entered against the range for the setting as published on the relay setting sheet. If any setting entered falls outside the corresponding range for that setting, the relay immediately responds and prompts you to reenter the setting.

Page 445: Section 7: Communications
Section 7 Communications Instruction Manual Overview A communications interface and protocol are necessary for communicating with an SEL-700G Relay. A communications interface is the physical connection on a device. Once you have established a physical connection, you must use a communications protocol to interact with the relay. The first part of this section describes communications interfaces and protocols available with the relay, including communications interface connections.
Page 446 Communications Communications Interfaces Be sure to evaluate the installation and communications necessary to integrate with existing devices before ordering your SEL-700G. For example, consider the fiber-optic interface in noisy installations or for large communications distances. Following is general information on possible applications of the different interfaces.

Setting FTIME = OFF allows fast port switching (with no intentional delay). Fast port switching can occur within one processing interval (typically 4 ms to 5 ms) and can help with IEC 61850 GOOSE performance.

A higher-level device can act as a master to a lower-level device, but can only use the data types and functions implemented in the lower level device. For example, a typical SCADA master is a Level 3 device and can use Level 2 (or lower) functions to poll a Level 2 (or lower) device for Level 2 (or lower) data.

Appendix F IEC 61850 Communications Instruction Manual Features The SEL-700G Relay supports the following features using Ethernet and IEC 61850: ➤ SCADA—Connect as many as six simultaneous IEC 61850 MMS client sessions. The SEL-700G also supports as many as six buffered and six unbuffered report control blocks. See the CON Logical Device Table for Logical Node mapping that enables SCADA control via a Manufacturing Messaging Specification (MMS) browser.
Page 688: Introduction To Iec 61850
IEC 61850 Communications Introduction to IEC 61850 Introduction to IEC 61850 In the early 1990s, the Electric Power Research Institute (EPRI) and the Institute of Electrical and Electronics Engineers, Inc. (IEEE) began to define a Utility Communications Architecture (UCA). They initially focused on inter- control center and substation-to-control center communications and produced the Inter-Control Center Communications Protocol (ICCP) specification.
Page 689: Iec 61850 Operation
IEC 61850 Communications IEC 61850 Operation The IEC 61850 document set, available directly from the IEC at iec.ch, contains information necessary for successful implementation of this protocol. SEL strongly recommends that anyone involved with the design, installation, configuration, or maintenance of IEC 61850 systems be familiar with the appropriate sections of these documents.
Page 690: Table F.2 Example Iec 61850 Descriptor Components
IEC 61850 Communications IEC 61850 Operation custom data models. Instead of having to look up data in a profile stored in its database, an IEC 61850 client can simply query an IEC 61850 device and receive a description of all logical devices, logical nodes, and available data. Unlike other Supervisory Control and Data Acquisition (SCADA) protocols that present data as a list of addresses or indices, IEC 61850 presents data with descriptors in a composite notation made up of components.
Page 691 IEC 61850 Communications IEC 61850 Operation IEC 61850 GOOSE objects can quickly and conveniently transfer status, controls, and measured values between peers on an IEC 61850 network. Configure SEL devices to respond to GOOSE messages from other network with Architect software. Also, configure outgoing GOOSE ERATOR messages for SEL devices in Architect.
Page 692: Table F.4 Buffered Report Control Block Client Access
IEC 61850 Communications IEC 61850 Operation Reports The SEL-700G supports buffered and unbuffered report control blocks in the report model as defined in IEC 61850-8-1:2004(E). The predefined reports shown in Figure F.1 are available by default via IEC 61850. Figure F.1 SEL-700G Predefined Reports There are 12 report control blocks, six buffered reports and six unbuffered.

Page 694: Figure F.2 Sel-700G Datasets
IEC 61850 Communications IEC 61850 Operation Datasets Datasets are configured using Architect and contain data ERATOR attributes that represent real data values within the SEL-700G device. See Logical Nodes for the logical node tables that list the available data attributes for each logical node and the Relay Word bit mapping for these data attributes.
Page 695: Figure F.3 Goose Quality
IEC 61850 Communications IEC 61850 Operation The time stamp is applied to all data and quality attributes (Boolean, Bstrings, Analogs, etc.) in the same fashion when the relay detects a data or quality change. However, there is a difference in how the relay detects the change between the different attribute types.

Synchrophasors Settings for Synchrophasors PHCURR PHCURR selects which current side (X or Y or Both) to include in the data packet. Consider the burden on your synchrophasor processor and offline storage requirements when deciding how much data to transmit. This setting is one of the seven settings that determine the minimum port SPEED necessary to support the synchrophasor data packet rate and size.
