With Assetguard MVC, Siemens has developed a new monitoring system for circuit-breakers in medium-voltage switchgear. The system monitors, in particular, the operability of the circuit-breaker drive, which is often exposed to harsh ambient conditions and yet rarely trips.
Over the years, the mechanical components can become dirty and fail to work in the worst case scenario. The monitoring system checks the reliability of the triggering system, the effectiveness of the closed circuit and the condition of the primary contacts. If the measured values do not match the preset values, the system signals the need for the maintenance of a component such as a switch or the drive.
This allows more efficient planning of maintenance routes and possible component replacement, making the switchgear more reliable and preventing the expense of unscheduled intervention.
To simplify the installation and configuration of the monitoring system, all functional components – power supply, data acquisition system and data memory, optical fiber communication system and the web server for data visualization – are designed as a switchgear cabinet slide-in module and accommodated in a 19-inch housing.
The integrated data memory also records measured data before the actual switching operation, analyzes the measurement curves and compares characteristic points with the preconfigured limit values.
If these limit values are exceeded, the system sends an alarm to the control center, where any maintenance activities that may be necessary are initiated immediately. One slide-in module can monitor six circuit-breakers. Each add-on module ensures that up to 54 additional circuit breakers can be checked.
Assetguard MVC can be integrated as a standalone component in SCADA (Supervisory Control and Data Acquisition) and ISCM (Integrated Substation Condition Monitoring) systems. The devices can thus be combined with other monitoring systems, which also facilitates user-specific diagnoses using third-party equipment.
As a monitoring system for medium-voltage switchgear, Assetguard MVC also rounds out Siemens' monitoring systems for high-voltage switchgear (Assetguard PDM/Assetguard GDM/Assetguard CBM) and for transformers (Assetguard TXM).

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
