2. OneFit
Definition: “Retrofit”
- Refers to the addition of new technology or features to older systems

Benefits of Retrofit

Saving on CAPEX while benefiting from new technologies

Optimization of existing plant components

Adaptation of the plant for new or changed products

Increase in piece number and cycle time

Guaranteed spare parts availability

3. Circuit Breaker Retrofit
Pre-requisites for Retrofit

Condition of Switchboard: “Assessment of Equipment and Network Dependability”

Are the bus zones/bus bars insulation and integrity acceptable

Is the Panel metal work and framework acceptable

Are the spouts/bushings integrity acceptable i.e. heat stress etc.

Economical Viability to “Retrofit” versus “New” versus “Criticality”

8. OneFit
Solution Benefits
Maintenance and repair:

the Down time to install one unit is 8 to 10 hours depending on the amount of
wiring required

OneFit have all standard spare parts with all the benefits in terms of delivery
time and price

equipment and spare parts are interchangeable with new ABB extension
panels and additional switchgear

same operational interface and maintenance approach for the equipment
installed in OneFit and new ABB panels
Modernization Process:

The use of standard breakers makes them ready without any
modification for Future ABB replacement switchgear, providing
an optimized investment for the next substation renewal.

9. OneFit
Solution Benefits
Safety upgraded:

the original shutter system and all the relevant interlocking are replaced with
new standard ones installed from the factory on the OneFit system

shutter and circuit breaker movement are interlocked to enable all necessary
safety features

the dielectric properties are increased thanks to the installation of a new
insulation plate

depending on which OneFit package is chosen, apparatus racking behind a
closed door and remote racking are available
Standards:

OneFit solutions are type tested according to latest IEC
Standards: 62271-1 (for the frame) and 62271-100 (for the
circuit breaker) when the original panel is provided to perform
the tests. Otherwise ABB can provide a technical extension certificate.
