DEVICE OVERVIEW CHAPTER 2: PRODUCT DESCRIPTION
The protection system consists of a distributed process interface (data acquisition and
tripping) architecture using GE HardFiber
the B95
The functions of the B95
Plus
.
Plus
include the following:
Bricks, with centralized processing performed by
• Multi-zone differential protection with both restrained (dual-slope percent or biased)
and unrestrained (unbiased or instantaneous) functions incorporated. Differential
protection is fast and secure. Security is achieved by using a reliable current
transformer (CT) saturation detection algorithm and a directional comparison
operating principle. Security is further enhanced by support for redundant process
interface (Bricks). Three-phase tripping is supported; differential protection operands
are provided for individual phase tripping.
• Interfaces with up to eight HardFiber Bricks per process card. The B95
Plus
can contain
one or two process cards.
• Supports up to 12 bus sources per process card. A single bus source is used to
interface a network element connection to the bus, such as a feeder, line, transformer,
capacitor, or reactor. A single bus source is used to interface a bus tie disconnect. Two
bus sources are used to interface a bus tie breaker.
• Dynamic bus replica functionality and multi-zone protection is supported allowing
application of the B95
Plus
to multi-section reconfigurable buses. A zone expansion/
contraction to an open breaker feature is included.
• Check-zone functionality can be configured by programming one of the differential
zones to enclose the entire bus.
• Supports up to two undervoltage functions per process card for differential protection
supervision purposes.
• End-fault protection (dead-zone protection) is provided for each bus source.
• A breaker fail function with three-phase tripping support and fast resetting current
detectors is provided for each bus source.
• An instantaneous phase overcurrent function is provided for each bus source for
possible supervision purposes.
• An inverse time phase overcurrent function is provided for each bus source for
possible backup protection.
• An isolator position resolution and monitoring feature monitors 48 isolators per
process card.
• A CT trouble monitoring function is provided for each zone of differential protection.
Voltage and current metering are built into the relay as standard features, as fundamental
frequency-only root mean square (RMS) scaled magnitude and angle (phasor).
Diagnostic features include an event recorder capable of storing 4,096 time-stamped
events plus 4,096 time-stamped events per process card. Oscillography is userprogrammable as to sampling rate (up to 128 samples per cycle), content, writing mode,
and record length. The internal clock used for time stamping can be synchronized with an
IRIG-B signal or using the simple network time protocol (SNTP) over Ethernet. This precise
time stamping allows the sequence of events to be determined throughout the system.
Events can also be programmed using FlexLogic
TM
equations to trigger oscillography data
capture, which can be set to record the measured parameters before and after the event
for viewing on a computer. These tools significantly reduce troubleshooting time and
simplify report generation in the event of a system fault.
On the communications card, either of the two Ethernet ports can be used for supervisory
control and data acquisition (SCADA) access, the programming of settings, and the
monitoring of actual values. These two Ethernet ports have both 100Base-TX and
4 MULTILIN B95

CHAPTER 2: PRODUCT DESCRIPTION DEVICE OVERVIEW
100Base-FX interfaces, and they can be used to provide fast, reliable communications in
noisy environments. These ports support TFTP, SNTP, IEC 61850, Modbus/TCP, and IEC
60870 protocols. DNP 3.0 and IEC 60870 cannot be enabled at the same time.
A third Ethernet port supports engineering access using the EnerVista B95

Advanced functionality allows the user to access comprehensive information without
having to navigate through conventional displays and keypads. Information displays on
two graphical display panels on the front panel. One serves as a digital annunciator and
the other, called the HMI, displays mimic diagrams, phasor plots, and other information.
The configurable, color LCD annunciator on the front panel eliminates the need for LEDs
and separate annunciator devices. Any contact input, remote input, or internally
generated logic operand can be assigned to each indicator, as well as any analog
operand. Up to 288 indicators can be assigned. The display can be configured for 12, 24, or
48 indicators per page. A separate self-test message page on the annunciator panel
displays error messages about device health.
The HMI panel provides easy access and visualization of device information, ranging from
the graphical and numeric display of bus source current phasors, voltage source phasors,
differential and restraint phasors, and tracking frequency, as well as a display of sequence
of events and a transient records list. The HMI can display a mimic diagram that provides
the status of each bus source’s breaker and isolators. Many bay configurations can be
realized through the setting of the device.

CHAPTER 2: PRODUCT DESCRIPTION HARDFIBER OVERVIEW
HardFiber overview
The GE HardFiber Process Bus System allows copper wiring to be replaced in substation
switchyards with optical fiber. The system includes all physical components required for its
installation: relays; factory pre-terminated fiber cables; fiber crossconnect panels; factory
connectorized copper cables; and switchyard I/O interface devices known as Bricks. The
Bricks implement the concept of an IEC 61850 merging unit, expanded to optically connect
relays with all types of input and output signals in the switchyard, not just instrument
transformers. The relays are the proven GE Multilin Universal Relay (UR) series devices with
a decade-long field record, and they incorporate all major applications from a simple
feeder relay to a sophisticated generator protection package. With the release of the
Plus
, the HardFiber system can also be used for the protection of large and dynamic
B95
buses.
Figure 3: GE HardFiber Brick top view
The HardFiber system replaces copper wiring between power apparatus in the switchyard
and protection and control devices in the control house with off-the-shelf components that
use standard physical and logical interfaces. As such, it shortens deployment time, reduces
labour requirements, facilitates work transfer, improves quality, simplifies procurement,
and improves safety.

NOTE:
Control power supplied to the unit must be connected to the matching power supply
terminal of the unit. If the voltage is applied to the wrong terminals, damage can occur.
NOTE:
The B95
Plus
, like almost all electronic relays, contains electrolytic capacitors. These
capacitors are well-known to be subject to deterioration over time if voltage is not applied
periodically. Avoid deterioration by powering up the unit once a year.
The power supply card provides a critical failure relay, with form-C contacts that are
energized once control power is applied and the relay successfully boots up with no critical
self-test failures. If ongoing self-tests detect a critical failure or power is lost, then the
critical failure relay de-energizes. This feature gives external indication when the relay has
failed.
Extensive filtering and transient protection has been incorporated into the unit to ensure
reliable operation in harsh industrial environments. Transient energy is removed from the

to the cubicle ground bus using a 10 AWG or larger stranded wire or ground braid. Do not
daisy-chain grounds with other relays or devices. Each is to have an independent and
direct connection to the ground bus.
The control power to the power supply card is protected by a non-replaceable 4 Amp sloblo fuse. 14 AWG or larger stranded wire is recommended for control power connection. A
ring terminal is recommended to ensure integrity of the connection. The rated torque for
the terminal screw is 9 in lb (1 N m). External downstream disconnects and external
overcurrent protection of 5 to 10 Amps are recommended for both control power inputs.

CHAPTER 3: INSTALLATION COMMUNICATIONS CARD (SLOT C)
NOTE
Communications card (slot C)
The communications card has two Ethernet ports designated as ports 2 and 3. They allow
the B95
computers running the EnerVista software. The ports are independent of each other. They
run all protocols supported by the relay.
Each port supports IEEE 802.3 100Base-FX on an ST fiber connector and IEEE 802.3
100Base-TX on an RJ45 copper connector. Only one of these two Ethernet media types can
be used on a given port at a given time; the relay automatically recognizes and uses the
particular media connected on each port .
The optical fiber sizes supported are 50/125 µm and 62.5/125 µm; the wavelength is
1310 nm. IEEE 802.3 100Base-FX light levels are used, and as such can be connected
directly to another 100Base-FX device without an attenuator. When splicing optical fibers,
the diameter and numerical aperture of each fiber must be the same. In order to engage
or disengage the ST connector, only a quarter turn of the coupling is required.
NOTE:
Ensure that the dust covers are installed when the fiber is not in use. Dirty or scratched
connectors can lead to high losses on a fiber link.

IRIG-B port
IRIG-B is a standard time code format that allows stamping of events to be synchronized
among connected devices within one millisecond. The IRIG time code formats are serial,
pulse width-modulated codes that can be either DC level shifted or amplitude modulated
(AM).
Third-party equipment is available for generating the IRIG-B signal. This equipment can use
a global positioning system (GPS) satellite system to obtain the time reference so that
devices at different locations can also be synchronized.

CHAPTER 4: ENERVISTA SOFTWARE ESTABLISHING COMMUNICATION VIA ETHERNET
Figure 5: Starting configuration
Establishing communication via Ethernet
There are two ways to establish communication for the first time between the EnerVista
software on the computer and the B95
Plus
: USB port or Ethernet port. You typically connect
using a USB cable, configure the IP addresses of the Ethernet port, then use Ethernet for
regular use of the unit. This section describes how to connect via Ethernet.
There are two Ethernet cable options. Use standard (blue) Ethernet cables to connect the
computer and the relay to the same Ethernet network. Or, use a crossover cable (typically
red) to connect the computer directly to one of the relay’s Ethernet ports.
Port 1, which is the Ethernet port on the main processor card in slot D, is recommended for
communication with the computer.
When using the crossover cable to connect the relay to the computer:
1. Manually configure Windows to use an IP address that is in the same subnet as the
relay. A straight forward way to do this set the computer’s IP address to one count
greater than that of the relay’s port. The computer’s subnet mask can be set to match
the relay’s mask.
2. If computer settings have been changed to support direct connection via a crossover
cable, restore them when finished with the connection.
When using regular Ethernet cables to connect the relay and computer to a switched
network, configure the relay’s Ethernet port settings with an IP address, subnet mask, and
gateway address compatible with the network using the USB communications described
in the preceding section. These settings are typically assigned by the network
administrator and entered into the relay.
1. Launch the EnerVista B95
Plus
Setup software.
2. Click the Quick Connect button on the left. In the window that displays, select
Ethernet in the Interface box, and enter the relay’s IP address. Click the Connect
button. The unit is now configured to communicate with the computer using Ethernet.

Three features facilitate selection and navigation:
• Quick select for operands
• Screen navigation feature for long lists
• Expanding and collapsing a settings table
Operand quick select
Using different mouse gestures, the user is able to initiate three different logic operand
selection modes in the B95
• By right-clicking on the far right side of any logic operand setting entry field, a dropdown list of all logic operands opens. In this mode, the user can use the scroll-bar to
scroll through the list until the required logic operand is visible, then click it to select it
and close the list. The user can also type a letter on the keyboard to jump down the list
to the next operand with a name starting with that letter.
• By right-clicking twice anywhere except the far right side of any logic operand setting
entry field, the field opens for keyboard entry of the operand name. (The first click
opens the operand quick select popup described as follows.) In this mode, as each
character is typed, the characters to the right are replaced to match the first operand
that matches the characters up to and including the new character. Characters that
do not match an operand are not accepted. Windows operating system's select, copy
and paste features also can be used in this mode.
• By single-clicking anywhere except the far right side of any logic operand setting entry
field, the logic operand quick select window opens. The window is generally as shown
in the figure that follows. The left-hand side displays a tree structure containing logical
groups of operands, and the right-hand side shows the operands of the tree element

Deploying settings files to multiple devices using settings templates
Settings templates simplify the configuration of multiple devices that protect similar
assets. In these situations, typically a large number of settings are identical among
devices, reflecting a common bus architecture and protection approach. The templates
allows engineers to configure and test these common settings, then lock them so they are
not available to others. For example, these locked-down settings can be hidden from view
to field engineers, allowing them to quickly identify and concentrate on the settings
specific to their application. The site-specific settings can be specified as editable and
made available to field engineers installing the devices. These are settings such as
protection element pickup values and current transformer (CT) and voltage transformer
(VT) ratios.
The settings template mode allows the user to define which settings are visible in the

be difficult to visualize using only the usual matrixes of settings. Graphical presentation
facilitates visualization.
The graphical editor operates on settings related to configuring the bus replica. Basically,
the graphical editor allows a schematic diagram of the protected bus to be constructed,
and by clicking on the isolators, breakers, and CTs in the diagram, settings entered that fit
the diagram to the actual bus. These settings are the same settings that can also be
configured by the usual methods from screens containing matrixes of settings, although
there are restrictions on opening both the matrix screens and the graphical editor at the
same time. The graphical editor also has a few "virtual settings" concerning the graphical
presentation that are not accessible from the matrix screens, but none of these affect relay
operation.

NOTE
The bus graphical editor does not display dynamic open/close status of the isolators and
breakers. It displays only how they are arranged.
NOTE:
The bus replica graphical editor displays only bus sources that are selected for display. It is
possible for enabled bus sources that therefore are contributing to protection operation to
be omitted from the display, and as a result their contribution overlooked by personal
using the display. Verification of the presence on the graphical display of all bus sources
shown as enabled on the Settings > Protection > General > Bus Sources screen is highly
recommended.
The following figure shows as an example a completed diagram. The wide short boxes

Not Exist" option. Second, when you select the “Solid Connection” option, the isolator is ON
and displays as a straight-through connection (for example if there is a permanent primary

A circuit breaker is greyed-out when its breaker opened settings are both set to OFF,
indicating that the zone expansion/reduction feature is not deployed.
The CT drawing convention used here is that an instantaneously positive primary current
entering one side of the CT symbol results in an instantaneously positive secondary current
exiting the same side of the CT symbol. That is to say, if polarity marks were to be drawn on
the symbol, then primary and secondary marks are on the same side of the symbol. The
side of the CT with the longer tail represents the side of the CT that connects to the Brick.
Thus when the tail is on the side away from the bus, primary current flowing into the bus
results in a positive relay current. If the CT origin settings are both None (meaning there is
no actual CT), the CT symbol is greyed-out.

BUS PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 5: SETTINGS – GENERAL POWER SYSTEM
NOTE
Nominal Frequency
Range: 50 Hz, 60 Hz
Default: 60 Hz
This value is used as a default to set the digital sampling rate if the system frequency
cannot be measured from available signals. This can happen if the Frequency Tracking
Function is Disabled, the Frequency and Phase Reference setting is None, or the signals
are not present or are heavily distorted. Before reverting to the nominal frequency, the
frequency tracking algorithm holds the last valid frequency measurement for a safe
period of time while waiting for the signals to reappear or for the distortions to decay.
Frequency Tracking Function
Range: Disabled, Enabled
Default: Enabled
This setting is set to “Disabled” only in unusual circumstances; consult GE Multilin for
special variable-frequency applications.
Frequency And Phase Reference
Range: None, all bus sources, and all voltage sources
Default: None
This setting determines which signal source is used (and hence which AC signal) for
frequency tracking and phase angle reference. The Clarke transformation of the phase
signals is used for frequency metering and tracking (V
= (2VA – VB –VC) / 3) for better
FREQ
performance during fault, open pole, and voltage transformer (VT) and current
transformer (CT) fail conditions.
The reference signal phase angle always displays zero degrees and all other phase
angles are relative to this signal. If the pre-selected reference signal is not measurable at
a given time, the phase angles are not referenced and typically continuously rotate.
The phase angle referencing is done via a phase locked loop, which can synchronize
independent B95
Plus
devices if they have the same AC signal reference. This results in
precise correlation of time tagging in the event recorder between different devices
during periods of IRIG-B unavailability. Note that the other devices are not typically
B95
Plus
units; they are UR or UR
Plus
devices or from other vendors.
Current Cutoff Level
Range: 0.002 to 0.020 per unit (pu) in steps of 0.001
Default: 0.020 pu
This setting modifies the current cutoff threshold. Very low currents (0.2 to 2% of the
rated value) are very susceptible to noise. Some customers prefer low currents to display
as zero, while others prefer the current to be displayed even when the value reflects
noise rather than the actual signal. The B95
Plus
applies a cutoff value to the magnitudes
and angles of the measured currents. If the magnitude is below the cutoff level, it is
substituted with zero. This applies to phase current phasor values. The cutoff operation
applies to quantities used for metering, general protection, and control, as well as those
used by communications protocols. Raw current samples available via oscillography are
not subject to cutoff.
The bus differential algorithm does not use cutoff.
NOTE:
Lower this setting with care because the B95
Plus
accepts lower signals as valid
measurements. Unless dictated otherwise by a specific application, the default setting
of “0.020 pu” is recommended.

NOTE
Voltage Cutoff Level
Range: 0.1 to 1.0 volts secondary in steps of 0.1
Default: 1.0 volts secondary
This setting specifies the voltage cutoff threshold. Low secondary voltage
measurements (at the fractional volt level) can be affected by noise. Some customers
prefer these low voltages to be displayed as zero, while others prefer the voltage to be
displayed even when the value reflects noise rather than the actual signal. The
Plus
applies a cutoff value to the magnitudes and angles of the measured voltages. If
B95
the magnitude is below the cutoff level, it is substituted with zero. This operation applies
independently to phase voltages and to phase-to-phase voltages. The cutoff operation
applies to quantities used for metering, protection, and control, as well as those used by
communications protocols. Raw samples of the voltages available via oscillography are
not subject cutoff.
NOTE:
Lower this setting with care because the B95
Plus
accepts lower signals as valid
measurements. Unless dictated otherwise by a specific application, the default setting
of “1.0 V” is recommended.

NETWORK SETTINGS CHAPTER 6: COMMUNICATIONS
In the single IP redundancy configuration, the port 2 IP address, subnet mask, and
gateway address are used for both ports 2 and 3, and the port 3 settings are ignored. All
communications traffic are normally routed on port 2. If a failure occurs (determined at the
hardware layer upon detecting loss of link signal on the active channel) then the traffic is
re-routed to port 3. Switchover to port 3 takes place in less than 10 ms from the moment
that the physical layer detects a failure. The device reverts from port 3 to port 2 as soon as
port 2 becomes available, regardless of the state of port 3. Switchover to port 2 takes place
in less than 500
ms. A link pulse is maintained in the transmit direction on both ports
regardless of the port in use. This ensures that communications are established with
minimal delays. An Ethernet broadcast message is transmitted immediately upon port
switch, thereby forcing all Ethernet switches in the network to immediately update their
routing tables.
In the dual IP redundancy configuration, each port has a unique IP address, with separate
subnet mask, and gateway address settings. Multiple client-server connections can be
opened on each port simultaneously. Under normal conditions, GOOSE messages are sent
on both ports and received on either.

IEC 61850 communications
Ethernet ports 2 and 3 on the communications card in slot C support the manufacturing
message specification (MMS) protocol as specified by IEC 61850. MMS is supported over
the TCP/IP-over-Ethernet protocol stack. Polling, unbuffered reporting, and buffered
reporting are supported. In addition, these ports support GSSE/GOOSE. The process card
ports intended for communication with Bricks support sampled values.
Remote inputs and outputs provide a way to exchange digital state information between
Ethernet-connected devices. The GSSE and GOOSE standards are used for this purpose.
GSSE/GOOSE configuration
IEC 61850 provides the following two fast mechanisms to exchange information between
relays in a substation at rapid speeds for performing interlocking and other time-critical
substation functions:
• GSSE — Generic Substation Status Event — Used for transferring status information
only
• GOOSE — Generic Object-Oriented Substation Event — Supports a variety of information types, including measured values
The B95Plus supports GSSE and two variants of GOOSE: the so-called Fixed GOOSE and
configurable GOOSE.
The sharing of digital point state information between GSSE/GOOSE equipped relays is
essentially an extension to FlexLogic, allowing for distributed FlexLogic
operands available to and from devices on a common communications network. The
publisher (relays that source the data) packages the values of user selected FlexLogic
or FlexAnalog operands in an Ethernet frame according to the GSSE/GOOSE protocol, using
a multi-cast destination address. The network sends each multi-cast frame to all or to a
configured subset of all the relays in the substation. Subscribers (relays that listen to the
data) set other FlexLogic
received frames according to their configuration settings.
FlexLogic operands selected for transmission are scanned eight times per power system
cycle; whenever a change of state is observed, the containing GSSE/GOOSE frame is
immediately transmitted with the new state value. FlexAnalogs selected for transmission
are also scanned but at a lower rate; whenever a value is observed that is outside its
configured bandwidth, the containing GSSE/GOOSE frame is immediately transmitted with
the new value. The bandwidth is initially 10%, but can be changed using the IEC 61850
and/or FlexAnalog operands from the specific values in the
by making

SetDataValues service. (The deadband extends to either side of the last reported value by
the set percentage of 46 times the base current for current quantities, or by the set
percentage of 275 times the voltage ratio setting for voltage quantities.)
To guard against loss of a change of state frame in the network, after the initial frame, the
frame is repeated. GSSE and Fixed GOOSE frames are resent 16, 32, 64, 128, and 256
ms
following the initial change of state frame. Configurable GOOSE frames are resent
according to the Retransmission Profile setting. To allow subscribers to detect loss of
communications and publisher offline, when no change of state has occurred, the frame is
resent at the rate of the Default GSSE/GOOSE Update Time setting. Publishers include in
the frame a time-to-live value, which indicates to the subscribers the time to wait for
another frame before declaring the connection failed.
In dual-IP redundant configurations, the IED transmits and listens on both ports
simultaneously.
Remote inputs and outputs provide a way to exchange digital state information between
Ethernet-connected devices. The GSSE and GOOSE standards are used for this purpose.
The sharing of digital point state information between GSSE/GOOSE equipped relays is
essentially an extension of FlexLogic, allowing for distributed FlexLogic
by making
operands available to and from devices on a common communications network. In
addition to digital point states, GSSE/GOOSE messages identify the originator of the
message and provide information required by the communication specification. All devices
listen to network messages and capture data only from messages that have originated in
selected devices.
IEC 61850 GSSE messages are compatible with UCA GOOSE messages and contain a fixed
set of digital points. IEC 61850 GOOSE messages can, in general, contain any configurable
data items.
Both GSSE and GOOSE messages are designed to be short, reliable, and have high priority.
GOOSE messages have additional advantages over GSSE messages due to their support of
VLAN (virtual LAN) and Ethernet priority tagging functionality.
The GSSE message structure contains space for 160 bit-pairs representing digital point
state information. The IEC 61850 specification provides 32 DNA bit-pairs that represent the
state of two pre-defined events and 30 user-defined events. All remaining bit-pairs are
UserSt bit-pairs, which are status bits representing user-definable events. The
B95
Plus
implementation provides access to the first 32 UserSt bit-pairs. The B95
Plus
also
supports a so-called “Fixed GOOSE” service, wherein the data set consists of 32 DNA
members and 32 UserSt members. Each member contains the same information as a bitpair.
The IEC 61850 specification includes features that are used to cope with the loss of
communication between transmitting and receiving devices. Each transmitting device
sends a GSSE/GOOSE message on power-up, when the state of any included point
changes, or after a specified interval (the default update time) if a change-of-state has not
occurred. The transmitting device also sends a hold time that is the GSSE equivalent of
time-to-live (TTL) in IEC GOOSE messages.
Receiving devices constantly monitor the communications network for messages they
require, as recognized by the identification of the originating device carried in the
message. Messages received from remote devices include the message TTL allowed. The
receiving relay sets a timer assigned to the originating device to this time interval, and if it
has not received another message from this device at time-out, the remote device is
declared to be non-communicating, so it uses the programmed default state for all points
from that specific remote device. If a message is received from a remote device before the
TTL expires, all points for that device are updated to the states contained in the message
and the hold timer is restarted. The status of a remote device, where “Offline” indicates
non-communicating, can be displayed.

64 items within the data set, a unique name, VLAN ID, and priority and work as

configured for transmission within each of the eight transmissions can be a combination
of digital and analog points. A digital status change or an analog point exceeding its deadband setting will cause the associated data set to be transmitted within 1

Plus
IEDs and devices from
other manufacturers that support IEC 61850 GOOSE.
Items programmed for GOOSE messages 1 through 8 have changes in their values
checked for change once per protection pass for digital data and less often for analog
data. When a change is detected, a GOOSE message is transmitted immediately and
repeated several times as determined by the Retrans Profile setting. When no change is
detected, GOOSE messages are sent periodically at a rate determined by the Default GSSE/
GOOSE Update Time setting to allow subscribers to verify link integrity and to
communicate the values to subscribers that have just started up or have just had their
communications restored.
IEC 61850 GOOSE messages contain a number of configurable parameters, all of which
must be correct for successful data transfer. It is critical that the configured datasets at the
transmission and reception devices are an exact match in terms of data structure and that
the GOOSE addresses and name strings match exactly. Manual configuration is possible,
but third-party substation configuration software can be used to automate the process.
