High Voltage Switchgear Monitoring and Diagnostics: 

Step 2 - Address

Asset data management

The challenge:

The goals of condition monitoring are straightforward: extended component life, reduced lifecycle costs, avoidance of dangerous or environmentally hazardous conditions; and avoidance of penalties by predicting and preventing equipment failures. As Siemens’ research has revealed, the majority of forced outages are predictable, which presents network operators with a tremendous opportunity.

But while online condition monitoring has great potential, collecting data is not an end in itself. The crucial factor is using the data for higher-level analyses. Siemens harnesses the “power of data” by processing and analysing the data collected, providing a sound basis for action, for both daily operations and long-term planning of asset performance management.

Our solution:

Siemens asset data management for substations and enterprises helps operators translate collected online condition monitoring data into useful knowledge. This is achieved by integrating multiple applications in a platform called Integrated Substation Condition Monitoring (ISCM). This integration can occur in the substation, centrally for more than one substation, or a combination of the two.

The ISCM substation or central system functions as a host for all monitored substation equipment – from one asset to entire substations. The incoming data is processed for further analysis and diagnostics and presented to each user through a user interface. Whatever the operator’s condition monitoring expertise, the user interface offers a clear understanding of what may be wrong.


This is a key benefit of the ISCM system: starting with a complete substation view, a problem is indicated and then assigned to the relevant asset. Experts can use the expert interface to validate the automated diagnosis or to perform a more thorough investigation. Asset Managers can then make informed decisions on which network components need to be maintained, repaired or replaced. These additional services can also be provided by Siemens Customer Services.

Analyse the data to address the condition of your switchgear

Using condition monitoring for daily operation as well as for asset management requires the proper analysis of the data revealed by the initial assessment. Asset data management is therefore the essential next step after installing online condition monitoring products.

Siemens’ asset data management offering converts condition monitoring data into usable information for operations and asset management. Our portfolio of products and services bring the information from different condition monitoring products together in a comprehensive system, independently of which monitoring product is used.

The result varies from compact to large central (enterprise) condition monitoring systems, ready for proper asset management according to the latest standards.

All monitoring products are available as stand-alone products or system-integrated in a Substation Monitoring Project. Substation Monitoring Projects integrate host all monitored assets on one platform – the Siemens ISCM platform. This system makes the visualised data available in the substation, at a central place in the office or anywhere at a tablet PC. Furthermore it defines how the alarm handling, diagnosis and reporting is implemented. Additional data available in SCADA systems can be combined to gain a more comprehensive picture on the state of your assets.

•    Specific application screens are available for MV Switchgear monitoring and Transformer monitoring.

•    Starting with a complete substation view, a problem is indicated and assigned to the affected asset.

•    The platform supports a high quality decision-making process regarding further actions, in case of alarm signals and                warnings.

•    Generated tendency indications help to decide whether an alarm needs immediate action or scheduled maintenance.

•    Furthermore, guidance to fault locations and an adequate risk assessment are presented to the user with essential                    supporting information.


ISCM avoids overloading SCADA data networks by hosting all the data acquisition and processing via knowledge modules. This means that it will not affect your SCADA system while diagnosing your assets. In order to share useful information between the two systems, integration in SCADA is available upon demand. Asset condition software solutions provide additional functions to ISCM-based monitoring systems.

The result? Asset data management enables unplanned outage avoidance, the early detection of impending failure, fewer repair costs, improved availability, and a more efficient, cost-effective maintenance strategy.
