About this guide
The purpose of this application guide is to
help the reader configure a Smart-Gear
PDS switchgear lineup. Each section
contains information important inselecting equipment to meet requirements
for todays modern medium-voltage
switchgear.
To make it easy to configure a Smart-Gear
PDS switchgear lineup, the various
selections in this application guide are
presented as building blocks, called
application modules. These application
modules are described in detail using
tables and one-line diagrams.
Each section contains information to help
the reader determine the powerdistribution system configuration that best
meets their application, protection,
operation and overall functionality needs.
Please note the information contained in
this application guide is a general
description of the technical options
available for Smart-Gear PDS. Certain
features or configurations may not be
applicable or appropriate for your specific
needs.
Smart-GearTM power distribution solution (PDS)
Siemens Energy, Inc., a world leader in
innovative technologies, has taken another
step forward by creating the total solution
in medium-voltage, metal-clad switchgear.
In response to our customers' need forstandard switchgear that is programmable
and self-monitoring, Siemens has
combined its advanced switchgear,
protective relay products and its
engineering experience to deliver a total
package to customers: Smart-GearTM power
distribution solution (PDS).
With Smart-Gear PDS, users are provided
the following features and benefits:
Reduced control wiring for increased
reliability digital and fiber-optic
circuits instead of hard-wired circuits
Self-monitoring feature-rich increased
operational reliability
Programmable easy to implement
complex schemes with flexibility for
future changes
IEC 61850 communication protocol
providing integrated control,
monitoring and protection
Usage-based preventive maintenance
notification
Faster commissioning and start up.
Smart-Gear PDS is equipped with standard
self-monitoring features, designed
specifically to enhance the performance
and reliability of the switchgear. With
Smart-Gear PDS, the user is notified in
advance of potential problems such as
those in trip circuit and space heater
circuits. Also, based on the usage of the
equipment, the user will be notified when
periodic recommended preventive
maintenance is needed.
Using IEC 61850 communication protocol,all control, monitoring and protection
functions are accomplished through a
redundant fiber-optic connection between
protective relays and bay controllers. This
communications capability reduces the
need for much of the control wiring
necessary to implement and change
complex schemes, resulting in reduced
field testing and commissioning time.
Nothing contained in this application
guide will constitute a warranty or
guarantee by Siemens that the Smart-Gear
PDS or the configurations described in this
guide are fit for your intended purposes.Your local Siemens representative will be
happy to assist you with configuring a
solution to meet your specific needs.
Application-based approach:
A new way of specifying switchgear
An application-based approach to
configuring switchgear offers a new way
of thinking. For example, with an
application-based approach, all switchgear
functions including automatic transfer
schemes, circuit breaker types, protection
schemes and other special switchgear
functions are described in terms of
application modules. When combined,
these application modules define the
operation and configuration of a Smart-
Gear PDS solution.
All software programs and digital and
hard-wired circuits used to perform specific
operations or protective functions are
referred to as apps, which are protective
relay hardware and software programming
(continuous function chart (CFC)
programming) designed specifically for
application modules.

OverviewSmart-GearTM PDS is a programmable and
self-monitoring power distribution solution
that combines Siemens type GM-SG non-
arc-resistant or type GM-SG-AR arc-
resistant, medium-voltage switchgear and
Siemens SIPROTEC protective relay
technology to offer one of the most
advanced standardized switchgear
solutions in the industry. With its standard
self-monitoring features and
programmable capabilities, Smart-Gear
PDS redefines how switchgear is specified,
engineered, operated, installed and
maintained.
Feature rich
Smart-Gear PDS is rich in standard
features, specifically designed to monitor
critical functions such as trip circuit
integrity, space heater operation, vacuum
interrupter wear, circuit breaker status,
operations and more.
In traditional switchgear, many of thesefunctions and features have to be specified
and engineered specifically to the order,
but with Smart-Gear PDS these self-
monitoring features are standard. For a list
and description of these features and
more, refer to the smart features section
beginning on page 6.
Switchgear
Smart-Gear PDS is available across the
entire GM-SG product family with Siemens
type GM-SG or type GM-SG-AR metal-clad
switchgear through 15 kV.
For more detailed information on Siemens
type GM-SG metal-clad switchgear, refer to
Siemens type GM-SG selection and
application guide E50001-A122-X-4A00,
Web site at www.usa.siemens.com/energy
or contact your local Siemens
representative.
Since a Smart-Gear PDS switchgear lineup
has fewer control devices, it provides
increased functionality and reliability. This
also means fewer control wires with
greater flexibility for modifications and
future changes or expansion with digital
circuitry.
Smart-Gear PDS is one of the most
advanced standardized medium-voltage
switchgear solutions in the industry.

OverviewProtective relays and metering
Smart-GearTM PDS is supplied with the most
advanced protective relays in the industry,
Siemens SIPROTEC protective relays. These
protective relays are fully equipped with
the advanced protection functions and
Ethernet-based IEC 61850 communications
protocol over a redundant fiber-optic cable
for high-speed data transmission. Refer to
protection functions and metering sectionbeginning on page 24 for a detailed
description of the protective relay
functions provided with Smart-Gear PDS.
For additional details on Siemens SIPROTEC
relays, refer to SIPROTEC Numerical
Protective Relays Catalog SIP 2008 E50001
K4400-A101-A5-7600, Web site at www.
usa.siemens.com/energy or contact your
local Siemens representative.
The difference
Smart-Gear PDS is equipped with more
features and benefits than traditional
switchgear. All applicable self-monitoring
features, described in the smart features
section beginning on page 6, are provided
with the standard package. These self-
monitoring features enhance the reliable
performance of the equipment. With
Smart-Gear PDS, less control wiring isrequired to implement simple or highly
complex control schemes. Communication
capability enables interface between
protective relays for each circuit breaker,
interface with other Smart-Gear PDS
switchgear lineups, remote control
capability and interface with many SCADA
systems deployed with current
communication protocols.
Simplification from design and
specification, to commissioning and
operation, is at the heart of Smart-Gear
PDS, the intelligent choice in yourselection of medium-voltage switchgear.

Smart features
Standard features
Circuit breaker operating cycles
monitoring
This smart feature alerts the user when the
drawout circuit breaker is approaching its
pre-set threshold of operating cycles for
scheduled maintenance. The threshold is
pre-set at the factory to provide advance
notification at 80 percent usage (20
percent of the remaining operations) of
the recommended operations cycle.
Trip-circuit monitoring
In the event of a fault, the user needs
confidence that the circuit breaker trip
circuit will open the circuit breaker. This
feature monitors the integrity of the trip
circuit and provides the user notification of
non-functionality of the trip circuit
resulting from failed trip coil or blown trip-
circuit fuse.
Close-circuit monitoring
(type SG-64 only)
Monitoring the status of the close circuit is
critical in cases where transferring and
redirecting power is required, such as with
a main-tie-main automatic transfer
scheme. This feature monitors the integrity
of the close circuit and provides the user
notification of non-functionality of the
close circuit resulting from a failed close
coil or blown close-circuit fuse.
Vacuum interrupter wear monitoring
This smart feature monitors the remaining
expected life of the vacuum interrupters by
calculating the accumulated load, no-load
and short-circuit interruption data. Basedon the calculation, the user is given
notification of vacuum interrupter contact
wear. Means for visual verification of the
vacuum interrupter during circuit breaker
inspection is standard.
Circuit breaker racking position
indication (type SG-64 only)
The position status of the circuit breaker is
connected to binary inputs on the
protective relay, and is thus available for
local and remote monitoring and control
logic. The circuit breaker positions include
connected, disconnected and test.
Integrated controls
Two things visibly different about Smart-
GearTM PDS compared to traditional
switchgear are fewer control devices andsignificantly less control wiring. With
Smart-Gear PDS, the circuit breaker control
switch function (CS) and lockout protective
relay function (86) are an integral part of
the protective relay. Having these control
functions in the protective relay enables
the user to change control logic
electronically without having to change
the hard-wired circuitry.
Integrated power monitoring
Main, feeder and tie circuit breakers are
equipped with integrated power metering(one percent accuracy) including current,
voltage and power measurement
functions. Current measurements include
Ia, Ib, Ic, min/max and min/max current
demand. Voltage measurements include
phase voltages and min/max. Power
measurements include peak demand kW,
peak demand kVAr and peak demand kVA,
min/max power factor, min/max frequency,
set-points and pulse counter. Min/max
data also includes date and time.
Programmable circuit breaker
control interlocking
Continuous function chart (CFC)
programming software makes digital
circuit breaker interlocking available for a
Smart-Gear PDS. This technology enables
interlocking of multiple circuit breakers in
the lineup, enabling user modification
without complicated and timely wiring
changes and retesting. All interunit
connectivity between circuit breakers is
through IEC 61850 communication
protocol over redundant fiber-optic
connections.

Smart features
Voltage transformer monitoring
Three-phase, wye-connected (required)
voltage transformers are monitored for
proper operation including blown fuse and
voltage transformer failure. As with other
event data, this information is retained in
the protective relay ready for local and
remote monitoring.
Current transformer monitoring
Current transformers are monitored for
proper phase and current summation.
Information is retained in the protectiverelay ready for local and remote
monitoring.
Bus protection (device 50B)
Reverse-zone interlocking is used to
distinguish a bus fault from a through-fault
and uses IEC 61850 generic object
oriented substation event (GOOSE)
messaging.
Space heater operation monitoring
Space heater functionality is important for
long-term operation and reliability ofswitchgear, particularly under conditions
of high humidity or in outdoor
applications. Many switchgear failures
result from improper use of space heaters
including instances in which the space
heaters were not energized or were never
wired to the power source. With Smart-
Gear PDS, the operation of the space
heaters is under constant monitoring to
improve the long-term reliability of the
power distribution system.
Large display (type SG-64 only)
A large display is provided with the
Siemens SIPROTEC type 7SJ6415 protective
relay solution and is provided for all main
circuit breakers.
IEC 61850 enabled
Each protective relay is equipped with
IEC 61850 communication protocol. More
information on IEC 61850 is included in
the communications and controls section
beginning on page 27.
Programmable main-tie-main transfer
scheme
CFC programming software makes digital
implementation of automatic transfer
schemes available for Smart-GearTM PDS.
Like the programmable circuit breaker
interlocking feature, this feature enables
the user to modify the scheme without
complicated and timely wiring changes
and retesting. All interunit connectivity
between circuit breakers is with redundantfiber-optic connections.
Fan cooling monitoring for a 4,000 A
circuit breaker(type SG-64 only)
This feature monitors the cooling fan for a
4,000 A circuit breaker. The cooling fan air
flow switch provides the input signal to the
protective relay for local and remote
monitoring.
Arc-flash detection
Arc-sensing protection is available with
Smart-Gear PDS.

Application modules
System application modules
System application modules are used to
define the operation and protection of the
entire switchgear lineup. All automatic
transfer and circuit breaker interlock
application modules are implemented with
CFC programmed protective relays, IEC
61850 communications over fiber-optic
cable. Tables 2, 3 and 4 describe these
system application modules in detail.
Automatic transfer application modules
With Smart-Gear PDS, four types of
automatic transfer application modules are
offered. These digital automatic transfer
schemes are configurable for automatic or
manual restore, open- or closed-transition
and preferred or non-preferred sources.
Refer to the definitions and terminology
section on page 35for detailed
descriptions of these terms. The available
automatic transfer application modules are
described in Table 2 on page 10. All time
delays and timing will be determined atthe engineering stage.
Application modules
This guide uses an application-based
approach described on page 2 to
configuring Smart-GearTM PDS. All
automatic transfer schemes, interlock
schemes, circuit breaker types, protection
schemes, remote control solutions and
interfaces, generator controller and
paralleling solutions, and other special
applications are described in Smart-Gear
PDS as application modules.
Application modules are the building
blocks used for configuring a Smart-Gear
PDS switchgear lineup. These modules are
pre-configured applications designed to
perform specific functions.

Application modules
Circuit breaker application modules
Circuit breaker application modules are
defined by the functional requirement (or
load type) of a circuit breaker. For Smart-
GearTM PDS, there are nine basic circuit
breaker application modules. These
application modules include main, tie,
motor feeder, transformer feeder,
distribution feeder, capacitor feeder and
generator circuit breaker applications, and
equipped space or future cell modules.
Each circuit breaker application module
(except future cell) is fully equipped with
the relay protection necessary to meet the
protection requirements of the specific
application and functions of the circuit
breaker (refer to protection functions and
metering section starting on page 24 for
additional details on the protective
functions of each circuit breaker
application module).
Note: For Smart-Gear PDS type SG-64, all
main, tie and feeder circuit breakers are
equipped with the Siemens type 7SJ6415
protective relays. For the Smart-Gear PDS
type SG-80, all feeder circuit breakers are
equipped with the Siemens type 7SJ80 (or
type 7SK80 for motor applications)
protective relays, while all main and tie
circuit breakers are equipped with Siemens
type 7SJ6415 protective relays.

Communicationsand controls
Because IEC 61850 is the global standard
for substation automation communication
protocol, it is the standard communication
protocol used for Smart-GearTM PDS. IEC
61850 communicates over TCP/IP networks
and/or substation LANs using high-speed
switched Ethernet (baud rate is 100 Mbps).It can be mapped to the most well-
established protocols, including GOOSE or
peer-to-peer messaging and Web services.
Since IEC 61850 is an open protocol that
supports communication for monitoring,
control and protection functions, it offers
significant advantages for interfacing
among circuit breakers within a lineup as
well as other devices throughout the
power distribution system.
All Siemens type SIPROTEC protective
relays used in Smart-Gear PDS are
equipped for IEC 61850 communications.
The automatic transfer and circuit breaker
interlock schemes described in application
modules beginning on page 9 are achieved
through continuous function chart (CFC)programming, and initiated by the
protective relays through IEC 61850
GOOSE messaging communication. This
digital capability significantly reduces the
number of control wires, especially
interunit (wiring between sections) control
wiring.
There are three communication and
control application modules, including
local control, remote-local control and
remote control application. Each control
and monitoring module is a building block
for configuring an advanced
communications network, in which the
local control and monitoring are the
foundation for all other control and
monitoring modules.

Communicationsand controls
Smart-GearTM PDS network:
local control and monitoring
Local control and monitoring is
accomplished among the Siemens type
SIPROTEC protective relays within the
Smart-Gear PDS switchgear lineup. The
protective relays are pre-programmed
using Siemens DIGSI 4 software to meet
the specific application requirements,
including automatic transfer schemes and
circuit breaker interlock schemes as
described in application modules on page
9. For Smart-Gear PDS, local operation andcontrol (closing and opening) of the circuit
breakers are accomplished through the
protective relay circuit. All automatic
transfer, circuit breaker interlocking and
lockout functions are accomplished
through protective relays within the local
digital network.
The interface among circuit breakers is
accomplished with CFC programming, IEC
61850, peer-to-peer/GOOSE messaging
and fiber-optic connections. The input/
output between a protective relay and a
circuit breakers is hard-wired.
Main-tie-main automatic transfer schemes
are accomplished with GOOSE messaging
and CFC programming, which is a more
reliable and flexible approach to system
automation.
