The total accumulated switched-off shortcurrents by a circuitbreaker or
the number of generator starts are a trigger for maintenanceNo need for big oversizing of primary equipment
In case of a shortage of electrical power, secure the available power to critical loads by
switching off the none important loads according to dynamic load tables
Optimizing the stability of the operation of the electrical generation- and distribution
network of an industryLimiting electrical import during peak time
and decreasing peak base chargeMaintaining a good Power Factor
The Human Machine Interfaces for all the electrical sub-systems can be integrated in
the Energy Management SystemSerial interfaces with protection & control units avoid spaghetti wiring & cable ducts
Power Control, Standby Optimization, n+1 Criteria, SCADA, etc. are performed by
the system and not anymore by the operators
