All data concentrated at a central location
SITRAM® integrated Condition Monitoring System from
TLM™ – Transformer Lifecycle Management™
Answers for energy.
SITRAM® iCMS –
all transformers on the monitor
The challenge:
Increasing competition is posing ever
greater challenges for energy suppliers. Necessary cost reductions are
leading to cutbacks in maintenance,
while longer plant running times are
causing components to be stressed
more heavily than planned. This is
especially the case for transformers.
In order to ensure reliable long-term
operation despite this situation, all
relevant operating parameters need
to be constantly recorded, collated
and compared centrally for all power
plants.
Transformers are the most expensive components in the energy supply and as such require
special attention.
SITRAM® iCMS assists network operators
in making use of synergies with the control and instrumentation technology. This
achieves optimized utilization of modules
and sensors, while at the same time the
control and instrumentation system provides a platform for transformer-specific
knowledge modules (KM). With the aid of
these modules, the operating and condition parameters of transformers can be
calculated precisely on the basis of the
measured values, design parameters and
event histories.
With SITRAM® iCMS ...
you receive real-time information about
the current condition of all transformers
in the network at a central location.
you improve the performance and service life of your transformers through
condition-based capacity utilization.
you reduce the costs over the entire
lifecycle thanks to minimized maintenance costs, lower spare parts requirement and longer service life.
you avoid unscheduled downtimes
through proactive maintenance based on
current condition data.
SITRAM® iCMS increases the performance and service life of your transformers
by collating all relevant data centrally in real time.

From the sensors ...
In order to be able to determine the
current condition of a transformer
accurately, numerous influencing
factors must be recorded and evaluated. The basis for this is provided
by ingenious sensors which transmit

The acquisition of data about a transformer’s condition is nothing new in
itself. The value-added feature of
SITRAM® iCMS lies in the collation of
this data at a central location, the Asset
Management Center. It takes the combination of many individual items of data
and their trends to create a comprehensive picture of the actual condition.
The data is analyzed by an efficient
knowledge management system with
several individually combinable modules. Since all modules are only used
once at the central location, software
license costs are kept to a minimum.
SICAM
The relevant operating and condition
parameters are computed on the basis
of the available measured data, design
parameters and historical events by
means of so-called knowledge modules (KM) based on the comprehensive
knowledge and many years’ experience
of a renowned transformer manufacturer. The knowledge modules communicate with the Asset Management
Center via an interface.
Maintenance and repair requirements
can be deduced from diagnosis of possible faults and forecasting of future
operating states.
