1 Transforming knowledge into availability SITRAM MONITORING from TLM Transformer Lifecycle Management Answers for energy.

2 Two key tasks for today s transformers: Managing values and increasing availability There are many reasons why your power transformers must function reliably around the clock: the high demands of your customers and processes, increasing load requirements, ever-scarcer backup power That s why you need monitoring solutions that provide constant information about the current status of your equipment so you can take proactive steps to ensure high availability and a longer service life. In many countries today, over 70 percent of transformers have been in use for over 25 years. The actual average service time often exceeds the estimated service life. Backup transformers are already being used for routine operations, and in many cases, spare parts are no longer available. Moreover, the transformers are not just being used at their nominal capacity but even to the maximum load capacity Under these circumstances, it s obvious that solutions are needed to provide operators with a clear picture of the status of installed transformers at all times. The primary goals: Avoiding unplanned downtimes and associated subsequent damage through risk prognosis and the early detection of errors Operating the transformers without incurring damage during brief periods of overload Using condition-based maintenance to streamline maintenance activities and minimize downtimes Detect faults earlier it s definitely more cost-efficient.

3 Always on alert: SITRAM Guards SITRAM Condition Monitor at an industry transformer SITRAM : Knowledge that increases availability Guards directly on the transformer: SITRAM Guards The family of SITRAM Guards is comprised of standardized, proven online sensor technolo gies as stand-alone solutions for individual transformers. Different kinds of warning instruments alert staff if deviations develop that might lead to errors or unplanned downtimes. This applies also if diagnostic or repair measures become necessary. GAS-Guard Online gas-in-oil analysis PD-Guard Partial-discharge monitoring BUSHING-Guard Bushing monitoring TAPGUARD On-load tap changer monitoring All key parameters at a glance: SITRAM Condition Monitor (CM) SITRAM Condition Monitor (CM) is a modular system which integrates information from individual sensors, and the SITRAM Guards, for every transformer. This monitoring of limit values with a set of standard interpretation algorithms is a cost-effective way to keep an eye on essential transformer parameters. The measured values are stored locally in a data acquisition unit and can be accessed remotely via various sophisticated communication interfaces. Various visual display systems are avail able depending upon the customer s philosophy. Whether on LCD displays or Web-based visualizations, the measured data can always be depicted in a user-friendly way. Example of user-friendly data isualization Working together, we can define the best-fit solution for your needs. SITRAM MONITORING has a modular structure and can be configured to precisely meet your requirements whether for individual transformers or complete fleets regardless of manufacturer, power, or year of manufacture.

This monitoring concept is designed to use control and instrumentation technology to take advantage of synergies. That means it optimally utilizes components and sensors. At the same time, the control and instrumentation technology provides the platform for transformer-specific Knowledge Modules (KM). The KMs can calculate the transformer s operating and status parameters on the basis of available measured values, design parameters, and historical events. More reliable decision making with specialized expertise: SITRAM MONITORING Service Siemens offers more than just hardware and software solutions for customized monitoring. If you wish, our experts will also consult with you personally; for example, to investigate possible sources of errors or to recommend and plan specific repair measures. If desired, our technical personnel can also handle delicate transformers via remote access. Choosing a monitoring solution from Siemens TLM Transformer Lifecycle Management also gives you the option of accessing our entire service portfolio.
