4. Retrofit Concept Retrofit Aim
RETROFIT means the implementation of modern components (primary switching devices and digital protection/control technology) in the existing MV installation with following benefits
Cheaper than a complete replacement
Short implementation time for replacement
Minimum shutdown of the switchboard
Remaining service life extension
Improved operator protection
Minimisation of further mainte- nance costs
Warranty on the conversion work
Spare parts availability for long time

5. Retrofit Concept The Benefits
Technology
Quality of Supply
Bus communication between breaker and control panel
Motorized rack-in rack-out operations
Through advanced switching features.)
Faster reclosing times
Large communication option to downstream and upstream
Reliability
Investment
Lower maintenance requirements.
Spare parts availability and delivery time for obsolete products can result in unexpected down time. (DOWN TIME)
Modern breakers features:
Number of operations.
Gas Control interlock.
Modern breaker mechanism are lighter and have longer mechanical life
Where limited funds are available of capital investment
Lets update equipment with lower investments
Lets plan customer maintenance budget
Reduction of insurance costs
By using new technology
Reduction of fire risk from old oil breakers
Relay on operation performance and lose of production/time
Offer opportunity of eliminating oil and airblast insulation through use of SF6 or vacuum interrupting technology
Dramatically reduce fire risk. (people & plants)
Reduced insurance costs. (people & plants) Increa-sing making current capacity protects personnel and equipment from unexpected failures.
Modern control circuits supports remote operations.
Additional safety standards embedded in modern breaker increases installation safety (i.e. internal/external interlocks)
Safety

23. Necessary Details for Standard Solution Generator Breaker Replacement
In order to use a distribution breaker like VD4 correctly, we have to calculate the DC current in case of generator short circuit
Why? The distribution breaker can only open when DC current is going to a reasonable low level where the energy can not destroy the breaker
The opening time might be increased and sometimes capacitors could be requested at generator site
! Please fill out the generator data request list !
