Sensproducts™ - from products to system intelligence

Transformers are a vital and decisive part of power grids – no matter if conventional or digital. The Sensformer™ will enable you to digitize this important keystone of your grid. Now your transformers are connective!

The digitally connected transformers Sensformer Advanced and Sensformer Edge offer great advantages: Transformer downtimes can be reduced, operation of the transformers can be made more flexible, and at the same time, costs can be reduced and environmental protection improved.

Both Sensformer versions contain the necessary sensors for entering the most important operating parameters – such as oil-level, temperature, and LV winding current. The biggest difference lies in data storage and analysis. While Sensformer Advanced saves the data in a cloud and processes it further, Sensformer Edge does this directly in the substation on a local computer.

The digital twin is an important element of Sensformer Advanced and Sensformer Edge. It allows operators to simulate the behavior of the physical asset in real time and thus creates a completely new type of experience and value-add applications: An active overload manager allows Sensformer operators to manage temporary overloads without compromising on lifetime. With a full temperature view, the current heat status can always be checked, a life consumption view gives indications on the residual lifetime of the asset. Furthermore, based on the digital twin, for highly developed applications, additional advanced sensors can be used on the asset, e.g. bushing, partial discharge or DGA sensors.

In 2019, Siemens Energy extended the revolutionary connectivity concept of Sensformer™ to the entire transmission switchgear product portfolio, called Sensgear™. Sensgear™ equipment provides

GPS and local weather information, as well as the operationally most important measurement signals: gas density, temperature, circuit-breaker counter, position & readiness.

Now, Sensgear™ functionalities are enhanced: Sensgear™ Advanced offers more than monitoring. It now upgrades this functionalities to enhance productivity using a digital twin. Moreover, the upgrade offers the chance to benefit from advanced intelligence by using artificial intelligence. New benefits for transmission system operators are:

Operation:

• increase power transmission by optimizing asset utilization and overload management
• minimize operational risks by tracking idle times and mechanical life trending

Service: 

• improve service effectiveness, health and safety through predictive maintenance
• less hours on equipment
• optimize gas monitoring, density trending & prediction

Lifecycle costs:

• virtual operation simulation and factory testing improves asset transparency, productivity and management
• optimize asset power transmission performance and asset lifecycle costs

Thanks to Sensarrester™ all main electrical functionalities of a surge arrester like surge counts, logbook of last events and total time of operation are now connective, allowing you to check the surge arrester’s status via online applications in real time. Sensarrester™ provides operators with a comprehensive and quick overview about their assets.

Sensbushing is able to generate data and results during service, with the huge benefit of simplifying the processing of the measured data for the overall bushing health status determination. AI-based algorithms will further improve asset management of bushings.
