Digital Substation Shift from a conventional to a digital substation
Primary components stand alone
Conventional Substation example AIS
Small foot-print: Integration
Digital Substation example AIS
Station local or remote HMI with asset management
• Lower OPEX for
operators
• Health and safety
• Less and smaller
control cubicles
• Linear NCIT / no
saturation
• Less cabling
• Less material
• Shorter cycle times
• Smaller foot-print
• Future proof thanks
to IEC 61850 CT & VT
Customer values
Digital Substation GIS and AIS Sensors (NCIT) replace bulky CTs and VTs

Monitoring
Equipment provides data for
maintenance optimization
Asset management
Risk analysis takes condition
and importance of individual
asset into account
Benefits:
• Reduces OPEX
• From time based to condition
and risk based maintenance
strategies
• Preventive maintenance
reduces unplanned outage and
shortens down time
Digital Substation Enable higher reliability and productivity in fleet service

Digital Substation Key benefits
The digital process
bus Substitutes 80% of the
copper signaling wires
Integrated non conventional
instrument transformers More accurate measurement, real
time, supports grid stability
Foot-print reduction Integration of functions
previously separate
(disconnectors, earthing
switches
short cycle times Automatic testing
Less wiring on site
Automatic monitoring Monitor the status of the equipment in
the cloud, condition based maintenance,
risk centered maintenance on the fleet
level, advanced data driven service for
utility customers
