Perfect guard for your Switchgear

Our high voltage Switchgear monitoring system caters to

Today’s Challenges all these challenges and delivers…

• Higher working safety

• Less travelling time
• Less outages
• Less unproductive time
• Remote inspection
• Optimized operational
and maintenance costs

Monitoring example: maintenance optimization of a car

Fixed schedule maintenance of an old car Event-driven maintenance of a modern car

Manual checks required e.g. oil level, screen water, tire pressure No manual checks required
Car condition is not continuously verified Thanks to sensors and data processing, Continuous monitoring of the
car is feasible
Maintenance based on fixed schedule
Event-drive maintenance; indication provided by the communication
This maintenance scheme leads to:
system
• Over maintained car
Monitoring allows to:
• Higher operational cost
• Optimize car maintenance
• Risk for unplanned shutdowns still high
• Lower operational cost
• Reduce the risk for unplanned shutdowns

Monitoring is simplifying the maintenance of the asset, reducing operational cost and the risk of unplanned shutdowns
