MV Switchgear Technology
is in our DNA
Eaton’s knowledge and understanding of industries,
applications, technology and products enables us to offer
customers safe, reliable and high performance solutions.
We have been part of the Medium Voltage switchgear
technology creation and therefore carry what’s needed
with us – always!
Complete MV switchgear solutions
The series of Eaton Medium Voltage systems offers switchgear
and components for applications in distribution networks (main
stations, substations and transformer stations) and industrial
power supplies. These technically high quality systems are air- or
epoxy-resin insulated and are always equipped with circuitbreakers based on proprietary vacuum interrupters.
The medium voltage switchgear systems carrying Eaton’s brand
are based on the use of vacuum circuit-breakers combined with
solid insulation material. This is an environmentally-friendly
technology in comparison with the methods used by many other
suppliers, which use SF6 as an insulation medium.
Eaton thus has a wide range of switching systems and
components that offer an environmentally friendly solution for
every application. Additionally, Eaton’s global service network
provides maximum customer support in all regions of the world.
Industry leading vacuum and solid insulation technology
Through more than eighty years of innovation and experience,
Eaton has developed environmentally friendly vacuum interrupters
capable of reliably switching both normal load currents and high
stress fault currents.
Eaton is one of the few companies in the world producing vacuum
interrupters and has succeeded in developing world class products
with international patents. This has been achieved through
company acquisitions over the years of Westinghouse®, CutlerHammer®, MEM® and Holec®.
Eaton’s range of
SF6 free switchgear
for Medium Voltage
To increase the dielectric strength of the vacuum interrupter,
Eaton has also designed vacuum interrupters that are encapsulated
in epoxy resin material. The medium voltage IEC circuit breaker
family utilizes this solid insulation technology that has been
catering to a wide range of applications for more than 40 years.

Xiria
The Product Family
Xiria is the name of Eaton's product family for a new generation of medium voltage
switchgear. The Xiria family started more than a decade ago with the introduction of
the Xiria ring main unit.
This ring main unit consists of a block containing three panels. Due to the quick acceptance and
worldwide interest in more configurations, Eaton consequently developed a four, five and two panel
block. Due to the fact that the individual units cannot be coupled and are limited in the number of
panels and protection and control equipment, the single panel version was developed. This single
panel version is called Xiria E. E in this case stands for Extendable.
The Xiria family includes multiple possibilities and configurations for Power consumption metering.
These configurations are indicated as Xiria M-versions. M stands for metering. The transformers for
power consumption metering can be either integrated into the block-type Xiria switchgear or housed
in a separate metering panel. This dedicated metering panel can be integrated with both the current
block type switchgear and the new single extendable panels.

Xiria M
(Metering)
Xiria E

The complete solution
By adding the Xiria E panel to
the current range of Xiria a
complete family, based on the
same and proven key technologies, is created. The Xiria
block type system is already
frequently used for transformers
stations, small industries,
4
heavy duty applications and
commercial buildings. With
the new Xiria E panel it is also
possible to use the system in
applications with higher
specifications and a bigger
number of panels.
Some applications are:
• Distribution substations
for utilities
• Wind power plants
• Bigger industrial applications
• Hotels
• Shopping centres
• Office buildings
• Infrastructure projects
(tunnels, subways, airports)
• Universities
• Hospitals
• Data centers
Xiria E
Modular Switchgear for Smart Grid Applications
Xiria E is the name of Eaton's new medium voltage
switchgear for smart grid applications. The system is
characterised by its high level of operational safety and
suitable for applications up to 24 kV.
The Xiria E switchgear is
designed around Eaton's
proven vacuum interrupters,
which require no maintenance
and are certified for 30,000
operation cycles.
reduced, as no regular testing
of gas pressure or other routine
maintenance is needed and
there is no high end-of-life cost
associated with ultimately
disposing of the equipment.
All live parts in the available
panels are single pole
insulated. The used materials
are shaped specifically to
provide optimum insulation
combined with excellent
thermal characteristics. In
addition, the insulation is
configured to provide effective
control over electric fields
around the used components,
thereby minimizing any risk of
internal arcing.
With panel dimensions of only
500 mm width and a provision
for cable connection from the
front, the Xiria E system is
economical in its use of
valuable floor space, and easy
to accommodate in even the
most restricted environments.
For locations where there is no
possibility to exhaust an
internal arc into cellar, the
system has the possibility to
exhaust into the room. This is
realized by means of a special
chimney at the back side with
integrated arc absorbers.
Within the Xiria E panels both
the primary parts and the
mechanisms are housed in a
fully enclosed housing which
protects the whole system
against environmental
influences.
The use of vacuum interrupters
and solid insulation means that
the Xiria E is environmentally
friendly. These technologies
ensure that this system is a
conservational alternative to
switchgear systems using
Sulfur Hexafluoride (SF6) gas
for insulation. The cost of
ownership is also significantly
When it comes to the safety of
the operating personnel the
Xiria E design leaves nothing to
chance. All parts are fully
enclosed by an internal arc
tested safe metal housing.
Besides that the panels in the
system are provided with direct
visible indication of the
integrated earthing and
ON/OFF-position by means of
inspection windows in the
front.

Basic Design
The Xiria E system is
modular in construction.
This ensures that any
panel combination and
sequence is possible.
In addition, the number of panels capable of being used in
an installation is unlimited as several sections can easily be
connected. As the panels can be quickly assembled and
connected, flexible commissioning of the switchgear is possible.
The panels in the Xiria E system are compact (500 mm wide),
resulting in considerable savings in costs and installation space.

Main Components
Vacuum circuit-breaker
The vacuum circuit-breaker uses a simple and reliable spring
charging mechanism for operation of the vacuum interrupters.
The mechanism contains a low number of moving parts and
makes no use of lubricants. It is completely housed in a sealed
for life enclosure and therefore needs no maintenance.
Features
• With environmental friendly vacuum interrupters
• Simple spring charging mechanism
• No use of lubricants
• Housed in a sealed for life enclosure
• Manual or motor-operated
• Position indication by means of inspection windows and
mechanical indicators
• Auxiliary contacts for Open/Closed position
2-position change-over switch
All panels are equipped with a change-over switch positioned
in the same sealed for life enclosure as the circuit-breaker.
The change-over switch consists of three shafts connected to
the busbars or earthing points. Since it is mechanically interlocked
the change-over switch can only be operated when the circuit
breaker is in the open position.
Features
• Manual-operated switch with 2 positions (service / earthed)
• Maintenance free
• Housed in sealed for life enclosure
• Auxiliary contacts for service / earthed positions
• Position indication by means of inspection windows and
mechanical indicators
• Mechanically interlocked with the vacuum circuit-breaker
Busbars
The busbars in the panel are housed in the same sealed for life
enclosure as the circuit-breaker and change-over switch. To prevent
a possible internal arc all busbars are single phase insulated.
Features
• Single phase insulated
• Air insulated
• Housed in a sealed for life enclosure
• Simple and robust construction
• Easy to couple

Eaton Core Technologies
Solid insulation
Polycarbonate and Thermoplastic elastomer (TPE) is used
as high-quality primary insulation
materials around live parts.
By applying Polycarbonate and
TPE for solid insulation our
design engineers can shape the
parts specifically for optimal
insulation, robust construction
and cooling purposes. In the
many years of experience with
design and manufacturing of
insulation materials, we learned
to construct smart single phase
insulated constructions. Xiria
utilizes optimal field control
through the special design of
all primary components.
Electrical field control
With conventional shapes for
primary components like
busbars and conductors, the
electrical field between the
phases and between phase and
earth is non-uniformly
distributed. In areas with high
field, partial break-through can
initiate avalanches resulting in
flash-overs. In-depth knowledge
about breakthrough phenomena
and field steering techniques
enable us to prevent flash over
completely. The result is a
particular compact design.
Vacuum technology: safe, compact and reliable
Eaton vacuum interrupters
consist of a ceramic cylinder,
housing a fixed and movable
contact. Movement of the
contact under vacuum
conditions is facilitated by a
bellow. A shield surrounding
the contacts prevents the
insulators from becoming
contaminated by metal vapour
produced during current
interruption. This shield also
ensures good potential
distribution over the insulator.
A typical feature of Eaton
vacuum interrupters is that
they are characterised by very
low arc voltage and short arc
times, resulting in very low arc
energy. Contacts wear in a
vacuum interrupter is therefore
virtually negligible. Vacuum
interrupters are maintenance
free and are certified up to
30,000 operation cycles.
9
Reliable and Safe in Operation
Eaton's proven technologies
have been integrated in the
design and development of
the Xiria in order to ensure
that the switchgear is safe
and has high operational
reliability throughout its
complete lifetime.
Experience and knowledge
gained over many years in the
areas of cast resin technology,
vacuum technology and
electrical field control have
been implemented.
The system has been
thoroughly arc fault tested
according to the latest standard
IEC 62271-200.
Preventing an internal arc
Within the Xiria design there are different technologies used to prevent an open arc.
Single pole insulated primary
parts
All high voltage parts are single
pole insulated. The insulation
materials used for this are
Polycarbonate and Thermoplastic elastomer (TPE), both
high-quality materials with
optimal insulation characteristic
resulting in minimised
dimensions.
Sealed for life fully enclosed
housing
Both the primary parts of the
unit and the mechanisms are
housed in a fully enclosed
(sealed for life) housing which
protects the whole system
against environmental
influences and therefore makes
it maintenance free. This
compartment can be classified
as non-accessible and has an
IP degree of IP55.
Use of Electrical Field control
Engineers designed the whole
construction of primary parts,
housed in the sealed for life
tank, based on Eaton's key
technology for electrical field
control. By means of special
shapes and dimensions the
possibility of an open arc is
minimized.
Protected Voltage
transformers
Ferro resonance can cause that
voltage transformers are
damaged and consequently
initiate an internal arc in the
switchgear. Our design
prevents that the voltage
transformers are affected by
ferroresonance. A resistor and
a saturable coil are installed in
the tertiary circuit of the
voltage transformer.
10
Routine tests
Various prescribed routine
tests are carried out during
the production of the switchgear. To assure quality, all
processes are in accordance
with DIN EN 9001. This means
that at every stage of
production the components,
circuit-breakers and current
transformers are inspected for
correct functioning. When the
entire installation has been
assembled, a thorough visual
inspection is carried out,
together with mechanical,
functional and electrical checks.
Philosophy on Internal arcs
Eaton always puts extra focus
on creating safe switchgear for
operators at all times. One of
the biggest potential threats to
operators is an internal arc in
switchgear.
Engineers therefore did everything necessary in design and
construction to prevent internal
arcs, despite the fact that it is
very rare for an operator to be in
front (without operating) of the
switchgear at exactly the same
time that an internal fault
occurs.
Eaton supports the philosophy
that it is best to avoid internal
arcs than to cure, in line with
the relevant standard
IEC 62271-200. Within the Xiria
design a double prevention
philosophy is used. Firstly, the
design is constructed in such a
way that an internal arc is
prevented. In the unlikely case
that an internal arc could occur,
the Xiria is equipped to provide
maximum safety to the
operator, and to control and
minimise damage to the rest of
the switchgear and room.
Controlling an internal arc
An internal arc in switchgear causes an overpressure supported by the release of fire and smoke.
By design, vacuum and air/solid
insulated switchgear has the
least environmental impact
after an internal arc event. The
impact of an arc is twofold: an
internal impact (in the
switchgear) and external impact
(in the switch room).
The overpressure created by an
internal arc will, in standard
switchgear, be guided out of
the switchgear by means of a
pressure relief duct. Next to
the duct a complicated and
expensive arc channel may be
installed, that guides the arc
output outside the switch
room. The Xiria design is
constructed in such a way that
both impacts are significantly
reduced and consequently a
less complicated arc channel is
needed.
No phase-to-phase short
circuits minimises pressure
Within the Xiria all high voltage
parts are single pole insulated.
The advantage of this single
pole construction is that the
only conceivable internal fault is
a single-phase short circuit, e.g.
due to a cable connection
failure (when single core cables
are connected, as is the normal
practice nowadays).
Arc absorber reduces
output impact
In case it is not possible to vent
into the cable cellar or into an
adjacent room, the Xiria design
offers the possibility to safely
vent into the switch room. In
this case a special arc chimney
is installed at the backside of
the panel. This arc chimney
contains integrated arc
absorbers that break and filter
gasses and fire significantly.
11
Safe in Use
The Xiria design contains some special features that guarantee the operator to work
safely with the different panel types.
What you see is what you get!
Visible isolation by means
of inspection windows in
the front
Earth position
When carrying out operational
actions and work on the cables,
it is vital to have unambiguous
status indications. When it
comes to safety of the
operating personnel Eaton
leaves nothing to chance. That
is why the Xiria design is fitted
with directly visible isolation by
means of inspection windows
in the front which makes the
isolating distance between the
cable and busbar system
directly visible. A visible, shortcircuit proof earthing can take
place via the load-break switch
or circuit-breaker.
Operating position
Capacitive voltage detection
system for verification of safe
isolation from supply
Logical mechanical and
electrical interlocks prevent
mal operation
Each panel type within the Xiria
family is equipped with a
standard three-phase Voltage
Detection System for voltage
testing to IEC 61243-5. The
VDS shows the operator if the
panel is isolated from supply or
not.
Within the Xiria design misoperation by an operator is
prevented by using different
interlocks. The interlocks are
mechanical and electrical. For
example electrical and
mechanical interlocks prevent
to operate the change-over
switch when the circuit-breaker
is switched on. All mechanical
interlocks are constructed in
such a way that they directly
block the mechanism.
Switching to service position
is only possible with closed
cable compartment
The door of the cable
compartment can only be
standard opened when the
circuit-breaker is in the earthed
position. After the door is
removed it is possible to switch
off the circuit-breaker for cable
testing. Next switching on to
service position is only possible
with the door positioned back
again.
Compartments protected
against penetration of
objects
Within the Xiria design it is also
not possible to accidentally
penetrate the switchgear by
part of a body or a tool.
For the latter all high voltage
compartments have an IP55
degree.
12
Smooth temporary design
All compartments of the Xiria
panels are designed in such a
way that the system is safe to
touch from the outside. By
using a smooth and smart
design it is not possible for the
operator to injure himself by
moving parts or parts that stick
out of the switchgear when
moving in front of the
switchgear.
Low Total Cost of
Ownership
The Xiria design guarantees very low costs related to
owning the switchgear during its entire lifetime.
The life-time costs can be split in the initial costs, installation cost,
service cost and finally, costs for disposal of the switchgear.
All costs of owning the switchgear are influenced by different
features of the switchgear. Within Xiria all these features are
constructed in such a way that the costs for the owner are as low
as possible of course with no concessions to the quality of the
switchgear.
Low initial costs
Initial costs consist of purchase,
transport, building and
installation costs.
Panel width only 500 mm
By using a combination of solid
insulation technology, electrical
field control and vacuum
technologies, Eaton's engineers
managed to construct Xiria E
panels with a width of
maximum 500 mm. Because a
typical switchgear installation
normally consists of a large
number of panels, this compact
design significantly reduces the
switch room size. The compact
design also makes Xiria E highly
flexible and economically
attractive when existing
installations are being replaced.
Cable connection from the
front (back-to-wall
arrangement)
Cable connection from the
front is a feature that saves
building costs. Due to this front
connection the rear of the
Xiria E can be installed close to
the wall of a building, again
reducing building cost.
12 kV and 24 kV panels in
same housing
The 12 kV and 24 kV versions
are both accommodated in the
same compact housing. This
means substantial savings on
building costs because the
same switchroom can be used
when the operating voltage is
increased (upgrading).
Arc chimney with integrated
arc absorbers
A standard option (in case there
is no possibility to vent down
or backwards) that reduces the
switchroom dimension is the
Xiria arc chimney with
integrated arc absorbers. In
normal switchgear, gasses
caused by an internal arc are
guided out of the switchroom
by means of an extra duct and
arc channel connected to the
switchgear. These additions
require extra switch room
space and consequently
increasing initial building cost.
Low service cost during
operation
Service cost consists of
maintenance, failure and
consequential cost. Besides
that the technical lifetime of
parts or modules will
determine the replacement
cost of the equipment.
Robust "lean" design with
minimum number of parts
Costs during service of a
switchgear can be caused by
damaged parts requiring
replacement, or by
maintenance parts that will not
reach their expected lifetime if
they are not serviced.
Within the Xiria design a
minimal number of
components are used. This
robust design with only the
necessary parts is designed
based on experience of building
switchgear for more than a
century.
No SF6-gas pressure checks
Switchgear that uses SF6-gas
as an insulation medium has a
leakage rate. To maintain the
isolation level within this type
of switchgear, the pressure of
the SF6 tanks must be checked
and refilled on a regular basis
during the unit's lifetime.
Within the Xiria, an owner does
not have to incur the extra
costs involved in checking and
maintaining the required
insulation level. The
combination of vacuum
interrupters for switching, solid
insulation and clean air as the
insulation medium, is
environmentally friendly and
maintains the same quality
level during the complete
lifetime of Xiria.
Primary parts and
mechanism installed in a
fully sealed for live enclosed
housing
Low end of life disposal
cost
Full recycling or re-use of
materials
The primary parts of the Xiria
have a lifetime of at least 30
years. Depending on the
location where the system is
installed the lifetime can be
extended. If for what reason
the decision is made not to use
the switchgear anymore the
Xiria can be handed over to
Eaton again. Next the switchgear will be dismantled and the
different materials can, and
will, be categorised. Because
no toxic materials are used in
the Xiria, dismantling is a less
complicated, more cost
effective and environmentally
friendly operation. The
dismantled and categorised
materials will be, depending on
the material, recycled or reused.
The biggest influence on the
quality of the primary and
moving parts in switchgear, has
the environment in and outside
the switchroom. These
environmental influences could
in the end cause damage to the
switchgear that should be
repaired. To prevent any
environmental influence on
the most critical parts in the
Xiria, all of these parts are
housed in a fully sealed for live
enclosure (IP55).
Product quality guaranteed
by prescribed routine testing
in the factory
During production of the
panels, various prescribed
routine tests are carried out by
specialists, making sure that
the panels achieve the quality
that they are designed for.
13
User friendly
First of all requirements is a safe and reliable installation.
Number two is an installation that is convenient and
efficient to operate.
The second aspect does not always get the attention it deserves,
but for Xiria most certainly did. The Xiria panels are designed to be
user friendly and are easy to operate.
Primarily, all operations can be carried out on the front side of the
panel. This means that both cable connection and user interface
for operation are positioned at the same front side of the panel.
The logically arranged control panel enable operators to do their
job as efficiently and safe as possible.
Easy and ergonomic connection of cables
Primary cables
Secondary cables
The cable cones of Xiria are
positioned on a height of
700 mm from floor level. This
height makes it relatively easy
for operators to connect the
primary cables. There is also
enough space in the cable
compartment to connect the
required number of cables
with connectors available on
the market.
Connecting the secondary
cables is carried out by
entering the low voltage
compartment of the Xiria E
from the top. The low voltage
cable terminals are positioned
in such a way that the operator
can connect the cables easily
within the compartment whilst
standing in front of the Xiria E.
Clear and simple control panel
The control panel on the Xiria is
positioned on a convenient
height for the operator. It is
directly connected to the
mechanism.
The mechanism is a hand
operated or hand/motor
operated spring charged
mechanism, connected to the
vacuum interrupters and the
change-over switch. It is
operated via two rotating shafts
on the front provided with the
necessary mechanical interlocks to avoid wrong operation.
For example an interlock is
built-in that prevents operation
of the change-over switch
when the circuit-breaker or
load-break switch is in the ONposition. Another standard
feature on the control panel is
the padlocking of the earthed
position. For padlocking the
position, the most common
padlocks available in the market
can be used.
Manual operation of the
switchgear is achieved with
one operating handle. This
handle can be used for
switching the circuit-breaker,
load-break switch and changeover switch. Operation is done
by inserting the handle in the
access holes in the front. In
case a motor-operated circuit-
14
breaker is requested a push
button will be installed in the
control panel for achieving this
function.
The mechanism is provided
with viewing windows on the
front for direct visual indication
of the earthed position of the
change-over switch and the
ON/OFF-position of the main
vacuum interrupter. The front
operating panel is also provided
with a black and white single
line intuitive mimic, showing
the positions of the vacuum
interrupter and the Earth/Busbar
position of the change-over
switch.
Each panel is provided with a
voltage detector mounted on
the front. It is connected via
internal wiring to capacitive
sensors inside the cable
connection cones. It shows the
presence of the primary voltage
on all three phases of the
primary cables connected to
the panel.
In case advanced protection
and control equipment is
requested, the low voltage
compartment positioned on top
of the panel, will house these.
Environmentally
friendly
Like all Eaton's other medium voltage switchgear, Xiria
is designed to be an environmentally friendly product
throughout the whole chain.
One of the key strategic initiatives of Eaton is to provide environmentally friendly products. Eaton realises that for this they should
look at their total product chain, from design to dismantling. The
optimal situation is that for each phase there is no damage to the
environment and at the end, all materials can be re-used again in
the same product (the Cradle-to-Cradle principle). The product
chain can be divided into four main blocks. These blocks are the
design (materials used) of the product, the assembly of the
product, the usage phase of the product and finally the
dismantling of the product.
Eaton's production plant in Hengelo (the Netherlands) acts entirely
in accordance with the rules and procedures of ISO 14001
environmental certificate during development and production
processes.
Environmentally friendly design
With respect to the design of
switchgear, the vision "the less
number of components the
better" applies. This because
every part must be manufactured and therefore impacts
on the environment. Next,
applies the affect of different
materials on the environment.
Use of minimised number of
components
Xiria is designed to use the
minimum of materials and
resources, without affecting
the strength of the system.
For example, Eaton reduced
the number of components
dramatically, compared to
conventional switchgear, by
using an simple spring charging
mechanism and integrated
compartments. This also
ensures straight forward
assembly with low labour cost.
Materials with no/less
impact on the environment
Eaton selects materials with
care. It is essential that they
are safe for personnel and the
environment - not just during
use, but at the end of service
life too.
Within Xiria a combination of
solid (cast resin) insulation and
air as insulation medium is
used. The solid insulation
technology, in combination with
electrical field calculations,
provides a very compact,
environmentally friendly design
for the switchgear. As the
switching medium, vacuum
technology is used within the
interrupters of the Xiria circuitbreakers. Xiria can be
completely recycled at the end
of its life without any problem.
No use of SF6 gas for
insulation or switching
Within medium voltage
switchgear SF6-gas is being
used, because of its good
insulating properties. Emissions
of SF6-gas from switchgear
contribute significantly to the
threat of the greenhouse effect
and associated climate change.
SF6 is on the list of greenhouse
gasses in the Kyoto protocol.
SF6 is the most potent of the
six main greenhouse gasses,
with a Global Warming
Potential (GWP) of 23,000.
In the 1980s, the Holec group,
as it was then, made a
fundamental choice not to use
SF6 as a switching and
insulation medium for medium
voltage equipment. In the
1980s, Holec had SF6 technology available in-house. The
main reason for not using any
SF6 in medium voltage equipment was the complexity of
the treatment required for the
toxicity of the gasses that have
been in contact with an arc,
and the need for additional
safety measures when used in
public locations such as
residential areas and shopping
centres.
Efficient use of materials
No service checks on site
Besides the energy sources,
special focus was placed on
the efficient use of material
during assembly. For example,
sheet steel plates are cut with
as little waste material as
possible. Residual material is
used within other product
components.
Because Xiria is designed for
a lifetime of at least 30 years,
the system needs no energy
usage for maintenance
activities during this long
period. Due to the green
insulation and switching
technology, there is also no
leakage of the SF6-gas during
its lifetime and no need for
extra maintenance activities on
SF6 pressure checks.
Minimal energy loss
during operation
Re-use or recycling of
materials
To prevent energy loss by the
system itself, Xiria uses a
minimum number of primary
change-over points. All the
available change-over points
use optimal surface contacts
and by this, prevent extra
energy losses over these
points.
During dismantling Xiria
switchgear is demounted into
parts and thereafter categorized
per material. Next the parts will
be recycled or re-used.
Because Xiria uses no SF6,
there is no loss of this gas
during dismantling of the
switchgear.

Exactly how you want it
Simple configuration, coupling and extension
Every application of this type of
system is unique, so Eaton
offers a large number of
different panel types and field
versions. If, in due course, the
end-user needs additional
capacity in the form of more
panels, Xiria E can easily be
extended to the right or left.
Flexible application of secondary apparatus, protection relays and substation automation
Eaton realises that end-users
have their own direction with
respect to the use of secondary
apparatus, protection relays and
substation automation within
the switchgear. The need for
customer specific apparatus
and relays was taken into
account during the development of the Xiria E. This
resulted in a system that
enables end-users to integrate
apparatus according to their
specification. Thanks to the
large number of protection and
control options, end-users will
always be able to construct an
Xiria E system that conforms
exactly to your requirements.

Range of Voltage
transformers
Protection and Control
equipment
All Xiria E panels can be fitted
with cast-resin insulated
voltage transformers (of the
requested transformer ratio and
class) for the voltage
measurement on the cable
side, or on the busbar side.
Both transformers can be
(dis-)connected safely and
easily.
The protection and control
equipment is located in the low
voltage compartment. This
compartment is completely
separate and has its own
access door. There is space on
the door for equipment such as
protection relays, test plugs,
meters, etc.
Range of Current
transformers
The epoxy resin insulated
current transformers are of the
ring core type. They are
positioned around the primary
conductors behind the cable
cones or around the primary
cables. All common
transformer ratios, outputs,
rated currents and classes are
possible.
The Xiria E is standardised for
the Woodward HighProtec line
relays series. However the Xiria
E is adaptable for the
installation of other brands. In
case more than one relay is
required, the low voltage
compartment can be extended.
Smart Grids
Equipment for (remote or local)
communication between
panels or automation systems
can also be installed in the low
voltage compartment. For
instance an Eaton remote
terminal unit (RTU) can be
applied. Having this possibility
makes the system the perfect
solution for current and future
Smart Grid applications.
