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 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
