A 1 Partition Specifications
The structure of the switchgears partitions and their features
are provided in 3 main headings as seen in the attached table.
A 1.1 Accessible Compartments
Interlock-controlled accessible compartment: Compartment
containing high voltage parts, intended to be opened for
normal operation and/or normal maintenance as stated by
the manufacturer, in which Access is controlled by integral
design of the switchgear and controlgear. Installation,
extension, repairing are not considered as normal
maintenance
Switchgears classification according to IEC 62271-200
Procedure-based accessible compartments: Compartments
containing high-voltage parts, intended to be opened for
normal operation and/or normal maintenance as stated by
the manufacturer, in which Access is controlled by suitable
procedure combined with locking. Installation, extension,
repairing are not considered as normal maintenance
Tool based accessible compartments: Compartment
containing high-voltage parts, that may be opened, but not
for normal operation and maintenance. Special procedures
are required. Tools are necessary for opening.
A 1.2 Non-accessible Compartments
Compartments that should not be needed to open and the
opening may damage the integrity which contains high-voltage.
A 1.3 Partition Class

between opened accessible
compartments and live parts of the
main circuit
Technical Information
A 2 Internal Arc Classification
It is a classification for metal enclosed switchgear and
controlgear, to ensure that in case of an internal arc the
defined conditions for protecting people are met and verified
by the appropriate test.
Three types of accessibility are defined, by considering
possible accessibility of Switchgears at site.
Accessibility Type A: Restricted to the authorized
personal only
Accessibility Type B: Unrestricted accessibility, open
to any people
Accessibility Type C: Accessibility restricted by
installation which is out of
reachable distance for pole
mounted switchgears. The
allowable minimum height of the
facility should be defined by the
manufacturer.
The metal enclosed switchgear and controlgear may have
different accessibilities for different directions. The following
codes should be used to define accessibility from different
directions.
F : Front
L : Side
R : Back
A 3 Loss of Service Continuity
It is a classification which defines the keeping of other
Switchgears and/or functional units in energizing position
when main circuit compartment of a switchgear is opened.
LSC2: It shows the having to other accessible compartments
out of the main busbar compartment of single busbar
switchgear and controlgear. Two subsections are
defined.
LSC2B: defines the Switchgears that opening and
interfering of switching compartment is allowed
while both cable and busbar compartment is
energized.
LSC2A: defines the Switchgears that opening and
interfering of switching compartment is allowed
while only busbar compartment is energized.
LSC1: defines the Switchgears that opening and interfering of
switching compartment is not possible while any of
busbar or cable compartments is energized since cable
and current-voltage transformers are located in a single
section.

The IEC 60298 was able to meet the standards while it was
utilized in previous years. However, due to the advancement of
the technology and developments in Switchgears designs, and
bringing the safety to the forefront, the standard was no able to
handle the power cuts of the systems as well as maintenance
needs of the users.

Switching Equipment and live parts along with its stainless
steel tank. It is separated from environment with a hermetic
enclosed steel tank and provides very high level of safety for
humans. The structure is designed to stand electro-dynamic
stress while it is working.

voltage signal lamps are located on the front panel.
Switching operations are performed with spring
mechanisms.
The positions of the Switching Equipment are shown on the
dynamic mimic diagram and voltage status can be monitored
with capacitive voltage indicator. The circuit breaker and
cable compartment is placed in an easily accessible way
from the front door which can be locked with a ground key.

In this sample, the energy has been transferred to a busbar by
an L unit which has a load separator and is not expandable to

not expand to the right and has a load separator as well as two
Outgoings by an F unit that has a load separator circuit breaker
and does not expand to the right.

In this sample, it is noted that the unit with “0 L” code cannot
expand to the left and has Incoming-Outgoing with a load
separator, “L” denotes Incoming-Outgoing with load separator
with no expandability either to the right or left, whereas the unit
that has "F 0" indicates that it is a Incoming-Outgoing unit with
circuit breaker and load separator and it does not expand to the
right. The unit with an “M” code is a measurement unit that
does not expand to the right or left and the Incoming or
Outgoing is only performed by a cable.

The SVC units have compact structures and provide sturdy,
safe mechanical operation.
SVC series Vacuum Circuit Breakers are also designed as
drawer type.
The electrical arc is insulated in the vacuum environment and
extinguished within the vacuum. When an internal arc formed,
the extinguishing process takes place within the vacuum tube;
hence there would not be any release to the outside. The
vacuum tube does not need any maintenance. Due to its
general characteristics its contact structure would not be
deteriorated. Therefore it can be used more efficiently when
compared to similar products.
E 1.1.1.1 Application Areas
SVC units are used in the following application areas:
Overhead transmission lines
Distribution and transformer centers
Cables
Transformers
Motors
Generators
Capacitor banks

E 3.2 Power & Energy Analyzers
Analyzers combine voltmeter, cosphimeter, wattmeter,
var-meter and frequency-meter into single equipment.
Therefore, it is possible to make savings from space, cable
and cost of equipment.
The data read can be transferred to SCADA or energy
Management Software on a computer via communication
ports that on the equipment. Since this data is kept in the
data base of the equipment, it provides simplicity in fault
determination. Furthermore consumption figures for the
past periods can be obtained hence planning towards future
can be made more consistently.
Due to digital outputs provided by the equipment it has
became indispensible part of SCADA systems. Transducer
usage becomes unnecessary by the help of some models
which have analog outputs.
Due to these features, the analyzers become essential part
of any management or automation system.

E 3.2.3 Energy Management Software
Actwin Energy Management Software reads all energy
parameters of Asset Power Analyzers and digital Electricity
Meters and records the data with time labels. It supports various
communication interfaces as well as communication protocols.
With different reporting and monitoring screens, various reports
and invoices can be created by the parameters recorded and can
be viewed in different formats in real time.
The most important feature of the software is that the data reading is
possible from multiple ports simultaneously and this increases
communication speed to a maximum level. In this manner, it is possible
to obtain more reading and create much more detailed reports.

E 3.3 Power Quality Recorders
Energy quality recorders are the necessary equipment for
analyzing the quality of electric networks according to
related standards (EN 50160, IEC 6100-4-7). The various
electrical parameters such as flickers, harmonics,
inter-harmonics, symmetric components, instability and
energy can be monitored simultaneously.
According to EN 50160, IEC 61000-3-6/7 standards, all
statistical data relating to quality of the energy of the
distribution and transmission systems including voltage sag,
swell and interruptions and so on are recorded by IEC
61000-4-30 class A and detailed reporting in conformity with
the standards are made.
