B30 - Protection, Metering, Monitoring and Control

Bus Protection

The B30 Bus Differential System provides,
secure, subcycle low impedance bus
protection for a single busbar with up
to six feeders. The B30 is ideally suited
in applications where high impedance
schemes were typically used. Overall
system costs can be reduced with the
B30, since there is no need for dedicated,
or interposing, CTs. The B30 comes with
advanced features, such as breaker
failure, CT trouble detection, undervoltage supervision, and dynamic bus
replica. With its extreme flexibility, which
includes a CT ratio mismatch of up to 32:1
between terminals, the B30 is the ideal
solution in a wide variety of bus differential
applications.

The B30 is the single point for protection, control, metering, and monitoring in one integrated device that can
easily be connected directly into DCS or SCADA monitoring and control systems like Viewpoint Monitoring.

Part of the Universal Relay family, the B30
comes with a variety of versatile features
truly integrating protection, monitoring,
metering, communication and control in
one easy-to-use device. The Universal Relay
family offers higher degree of modularity
in its design and functionality providing
superior performance in protection and
control meeting the toughest requirements
of the marketplace.

Bus Differential Protection
The B30 is based on a centralized phasesegregated architecture that does not rely
on extensive communications between
IEDs, an approach that increases overall
reliability.

primary protection is based on differential
and directional protection principles,
and uses a dedicated CT saturation
mechanism for additional through-fault
stability. This mechanism is capable of
detecting saturation of CTs as quickly as
two milliseconds into an external fault.
The overall system costs can be reduced
with the B30 since there is no need for
dedicated, or interposing, external CTs.
The two differential zones can handle two
small buses, split bus, or single bus bar
with supervision zone.

currents dynamically from the differential
zones. This allows the B30 to follow the
actual busbar configuration with no
external switching of CT circuits required.
The B30 also avoids blind and overtripping
spots in simple bus configurations.
Reliability is increased and costs reduced
by eliminating auxiliary relays that would
otherwise be used for switching physical
currents. The ability to monitor auxiliary
switches and a contact discrepancy alarm
also provides increased security.

Dynamic Bus Replica

Three-pole breaker failure (BF) protection
is available. The B30 system provides for
up to 6 BF elements that can respond to
currents and/or auxiliary contacts. The
current supervision provides fast reset

The B30 provides a dynamic bus replica
for each zone of differential protection.
Built-in programmable logic removes the
need for external auxiliary relays, and
provides the ability to include or exclude

The B30 provides fast and secure low
impedance bus protection with sub-cycle
tripping times averaging 0.75 cycles. The

Backup Protection
Backup protection is available with
instantaneous and time overcurrent
functions for each current input of the
B30 system. For supervision purposes, an
undervoltage function is also provided for
each voltage input of the B30 system.
• IOC Functions: Two separate IOC
functions are available for trip
supervision or other user-configurable
applications
• TOC: One TOC function is incorporated
for each CT input of the relay. Up
to 6 TOCs are available for backup
protection. The TOC function can use
standard or user- programmable
curves

• Voltage Supervision: up to two
undervoltage elements are available
per each VT input of the relay. This
function may be used to supervise the
current-based protection functions for
extra security

External Check-Zone
An optional external check-zone can
be used to prevent operation of the
differential protection due to CT troubles. If
one B30 current input is left unused and an
alternative set of current signals is available
from independent CTs, the currents can
be combined externally and connected
to the relay. Two phase overcurrent
elements are available to check the level
of this independently formed differential
current to supervise the main differential
protection.

IEC 61850 Process Bus
The IEC 61850 Process Bus module is
designed to interface with the GE Multilin
HardFiber System, allowing bi-directional
IEC 61850 fiber optic communications.
The HardFiber System is designed to
integrate seamlessly with the existing
Universal Relay applications, including
protection functions, FlexLogic, metering
and communications.
The GE Multilin HardFiber System offers
the following benefits:

time and separate settings for low-set
and hi-set are implemented. The BF can
be initiated internally from the busbar
protection or externally via input contacts
or communications.

System

• Communicates using open standard
IEC 61850 messaging
• Drastically reduces P&C design,
installation and testing labor by
eliminating individual copper
terminations
• Integrates with existing B30’s by
replacing traditional CT/VT inputs with
IEC 61850 Process Bus module
• No new Cyber Security concerns

Built-in Advanced Disturbance Recording
The built-in advanced disturbance recording function allows users to view the COMTRADE files and trouble shoot bus fault. The internal operation of the
B30 elements, logic, and outputs can be monitored in real time to simplify commissioning and troubleshooting procedures. Two cases are shown here:
External Fault:
Even with heavy CT saturation and with only 1 msec of saturation free current B30 is stable for through faults. See the Directional Comparison element
output, which adds additional security to the bus differential function
Internal Fault:
For internal fault the CT saturation flag is not set and the directional element output is safely ignored resulting in an operating time of less than 10 msec.

All the fault currents are
seen in one direction
Despite heavy CT saturation the external
fault is seen in the opposite direction
The bus differential element picks up due to heavy CT saturation
The CT Saturation flag is set safely before the pickup flag
The directional flag is not set

The bus differential element picks up
The CT Saturation flag is not set - no directional
decision required

Diagnostics
The B30 performs comprehensive
device health diagnostic tests during
startup and continuously at runtime to
test its own major functions and critical
hardware. These diagnostic tests monitor
for conditions that could impact security
and availability of protection, and present

and front panel display. Providing
continuous monitoring and early detection
of possible issues helps improve system
uptime.
