Maintenance on demand is possible through real time
monitoring of:
…with PISA or with an additional unit
• CB operating time
• drive temperature
• accumulated I2T
• contact displacement
• motor running time
• self checking devices
• SF6 density
• etc. etc.
Maintenance

PISA = Process Interface for Sensors and Actuators
• data preprocessing at the switchgear
• self-checking electronics and drives
• continuous SF6 density monitoring
... lead to condition based maintenance
