TMDS™ Transformer Monitoring & Diagnostic System
- Description
Selecting a transformer monitoring solution is a critical step in achieving your company’s Smart Grid asset management strategy. Transformer monitoring requires the integration of sensors, data management and analysis to turn sensor data into useful knowledge, and then an overlay of software applications to turn knowledge into actionable information. Appropriate online diagnostic tools can help utilities avoid unplanned failures, lower maintenance costs and extend useful transformer life.
TMDS™ delivers decision support to the right personnel in the context of actionable information
Siemens TMDS™ is an expert system combining multiple engineering models with advanced techniques of statistical learning, far exceeding existing monitoring concepts of simple measurement of operative condition with pre-fixed limits. Designed to provide transformer monitoring and diagnostics for transformers in a substation or across multiple substations, TMDS™ turns transformer monitoring data into actionable information by translating combustible dissolved gas, bushing capacitance deviation, moisture and other sensor measured data into diagnostic and prognostic messaging.
TMDS™ provides alarming and trending using models that work with rule based logic, derived from accepted IEEE/ANSI guidelines, to perform correlations on both measured and calculated data. Alarm messaging includes recommendations on maintenance activity as well as suggested loading should TMDS™ classify the observed deviation as severe enough that it may result in the damage or potential failure of the transformer.
The Siemens TMDS™ advantages include the following:
- Best-in-class transformer monitoring and diagnostic system
- Advanced detection of abnormal conditions
- Provides 24/7 access to current operational data, trends, alarm history and messaging from a central location or remotely
- Flexible, scalable architecture
- Easily installed on new or legacy transformers from any manufacturer utilizing existing sensors
- Automatically detects bad sensor data to avoid false diagnosis
- Specifically configurable for legacy transformers.
Configurable to monitor a single transformer or simultaneously monitor an entire fleet of transformers to support a customer’s centralized approach to asset management
Actionable information
- Delivers statistically relevant abnormal operating data and alarm conditions
- Indicates potentially related or causal relationships between transformer components and alarmed condition
- Provides maintenance support to address abnormal operation
- Suggests loading recommendations through the adaptation of models using actual field condition assessment data.
Flexible architecture
- Data available to enterprise data management system via OPC compliant interface to reduce cost of database management
- Fiber optic ring arrangement for improved system reliability
- Communicates with sensors by serial, analog and digital interfaces
- Supports fiber optic and wireless based communication mediums
- Can be combined with other asset monitoring systems via substation gateway.
