Safe, reliable, and
cost-effective retrofit solutions
Medium-voltage switchgear upgrade with vacuum circuit breakers
Answers for energy.
Selected retrofit
solutions from Siemens
The latest switching technology
is affordable
The power distribution business is
in a state of change: the demand for
electricity is still increasing around the
world – a development which is expected
to continue for the foreseeable future.
On the other hand, increasing market
liberalization demands new approaches
from power traders, utilities, network
owners, and also industrial electricity
customers, who all strive to remain at
the cutting edge of cost efficiency in
the highly competitive energy market.
Very often, parts of the network
infrastructure reach the end of their
service life early, create unforeseen
downtime and hinder the efficiency of
network assets that need to be kept
working at full capacity. Crucial elements
of the network, therefore, need to be
brought up to today’s safety and
operation standards. This is especially
true with switchgear, which is key to the
reliability of the entire power supply
systems. However, the replacement of
switchgear takes considerable time and
requires a substantial investment.

Siemens, the world’s leading supplier
of switchgear technology with the
most comprehensive product range, has
developed a range of retrofit solutions
for medium-voltage switchgear that
bring reliability, operational safety, and
technology up to scratch. The Siemens
retrofit solutions are the fast, futureoriented, and highly economical expert
solution whenever it comes to the
replacement of medium-voltage
switchgear that have become a bit
long in the tooth.
The Siemens retrofit solutions for
medium-voltage switchgear make
possible the cost-efficient implementation
of virtually maintenance-free state-ofthe-art vacuum switchgear technology
in the shortest possible time.

1.
At the initial stage of the retrofitting process
relevant information about the switchgear is taken.
This includes manufacturer, type, and serial number
of the original switchgear as well as technical
details, engineering drawings, and photos of the
switchgear and truck.
2.
Based on the data surveyed during the first project
stage, precise measurements are taken on-site or,
more often, from an old original truck.
All data are entered into AutoCAD, and the individual
solution is designed and engineered according to
the customer’s requirements. Stringent due
diligence tests and verifications are performed
within AutoCAD.
The switchgear to be retrofitted can remain in place
and in service. Temporary workarounds are not
required, which ensures continuous operation and
prevents impairment of service quality.

Installation
4.
About three months after the first steps of the
project were taken, the switchgear trucks arrive
at the customer’s site.
Thanks to stringent planning and production
processes, the need for adaptations on-site can be
kept to a minimum: most retrofit trucks come as
plug-and-play solutions. Downtimes are thus
avoided, and critical switchboards can always be
kept running. In most cases, it takes only a few
hours to install the retrofit truck.
Test
3.
A prototype of the retrofit truck is produced
and then extensively tested at the production site.
If required, the retrofit truck can be type-tested
according to IEC 62271-200 at an independent test
laboratory. Type-testing is standard for all standard
replacements of common Siemens, Reyrolle, and
Magrini Galileo switchgear.
Series production of the trucks will only start
once the prototype has successfully passed all
tests, which include:
mechanical tests, e.g. interlocks and drawability
dielectric tests
temperature rise tests
short-time withstand current tests
