SITRAM® Condition Monitor from TLM™ – Transformer Lifecycle Management™
Answers for energy.
SITRAM® Condition Monitor –
all key parameters at a glance
Transformers play a key role in power plants, transport
and distribution networks, and in industry. Continuous
recording and monitoring of the key parameters of the
active part, the tap-changer, the bushings and the cooling system is all the more important. As individual sensors only show parts of the overall picture, a monitoring
platform is needed to integrate – and jointly analyze –
data from all different kinds of sensors.
Siemens has developed a modular monitoring system
that allows you as the operator to cover all different kinds
of sensors, protocols and parameters as cost-efficiently
as possible.
With SITRAM® Condition Monitor …
you get a comprehensive picture of the current status, operating trends, and signals received from your transformers.
faults can be detected early and correct decisions can be taken on a safe basis.
you receive information for the economical use of
maintenance measures to extend the service life.
you’re on the safe side when it comes to labour safety and environmental protection.
The SITRAM® Condition Monitor can be used on all your
transformers, regardless of manufacturer and age. Cus­
tomer-specific solutions can be built on a basic version,
and it’s also no problem to integrate existing sensors,
for example as part of a retrofit solution.
The individual measured values are combined directly in
the switch cabinet of the monitoring system with a data
acquisition unit. Thanks to standardized interfaces, it’s
easy to integrate the SITRAM® Guards or other equipment.
The SITRAM® Condition Monitor is an open-ended system
offering a secure investment even if standards change or
additional requirements arise.
Boost your profitability. SITRAM® Condition Monitor provides a complete picture
of the transformer – for greater reliability and longer service life.

From data acquisition to asset protection
Keep an eye on all data – live andrecorded
Measured data from sensors and guards is combined in
the data acquisition unit and made available via a standard in­terface. The parameters for the limit values are set
in a teach-in phase and then monitored continuously. The
current status can be read directly on the transformer or
by remote access via the corporate network. All data is
archived for subsequent evaluation and for drawing up
trend analyses.
Tailored visualization
Determining the best possible data visualization basically
depends on the requirements at hand. That’s why we offer different options for presenting the measured data in
user-friendly form in any environment, from LCD display
to Web-based visualization.
SITRAM® Condition Monitor –
complete protection at a glance
Comprehensive overview
SITRAM® CM concentrates the data from individual
sensors to provide a complete picture of the actual
condition of your transformer.
Early fault detection
SITRAM® CM monitors all limit values and creates the
basis for reliable trend analyses. Faults are identified at
an early stage, and damages can certainly be avoided.
Short reaction times
In the event of deviations from the standard, service
measures from the TLM™-portfolio can be initiated.
Cost saving
Maintenance measures can be planned in good time.
Costs for faults are reduced and strategic decisions
are backed by long-term data sequences.
A wide range of applications
SITRAM® CM can be used on all transformers in power
generation, in industry and in the transmission and
distribution system:
• industrial transformers
• generator transformers
• strategically important transmission transformers
Vendor-neutral solution
Thanks to its flexible configuration capability, SITRAM®
CM can be used on transformers from all anufacturers.
Individual display
We offer a suitable visualization option – whatever
your requirements and environment are.
