Preventive Maintenance – PMP

3. ‘’Any maintenace activity is a cost’’
Maintenace theory Aim: Mind-changing
‘’Any maintenace activity is a cost’’
The customer has to understand that performing a correct and periodic maintenance is essential to:
- Reduce the total managing costs
- Use the resources according to needs
- Standard, directives and laws

4. Maintenace Theory Myths & Facts FALSE FALSE FALSE Common Myths
Circuit-breakers are maintenance free
Circuit-breakers Preventive Maintenance is just dusting down
The circuit-breaker is always in closed position so it doesn’t require any maintenance
Proven Facts
Circuit-breakers are protecting devices: periodical check on functionality and maintenance are required to guarantee the original performance level
Circuit-breakers Preventive Maintenance consists in checking the integrity of all the electrical and mechanical components to limit aging on components and prevent faults
All the mechanical and electrical components need maintenance (as lubrication) in particular in harsh environments.

5. Maintenace Theory Why maintaining Direct Costs Indirect/induced Costs:
Indirect costs
Direct Costs
Maintenance: personnel, materials
Indirect/induced Costs:
Higher risk in Health & Safety
Reduction of products lifetime
Management of urgency
Poor quality
Energy consumption
Environmental impact
Resource availabilities
Inefficiency in personnel
Insurance policies
Production Losses
Losses in market share

6. BUT Maintenace Theory Estimated lifetime
Based on ABB experience, it is possible to define average component lifetimes
BUT
a SITE SURVEY is always recommended.
It is performed by a circuit breaker specialist, who inspects the products, on-site spares, environment, fault history, etc...
The result of a site survey is a proposal of short and long term maintenance actions

7. ABB SACE Maintenance Portfolio Maintenance with ABB - benefits
ABB technicians are skilled and properly trained:
Before operating on the field spend at least 1 year in the production line
Regular courses to be updated on new products
By turns work in the internal assembly line for repair
Original Spare Parts
Right tools
Continuous communication between R&D/ Quality dep. and Service  Knowledge on CB updates (modification for improvements)
Why choosing ABB: Specialistic maintenance

8. ABB SACE Maintenance Portfolio ABB SACE offer (in accordance with EN 13306:2010)
Before a failure
Maintenance
After a failure
Preventive
Corrective
Predetermined
Urgent Maintenance: Aimed at bringing back the element in the status in which it could carry out the required function
Deferred Maintenance: At predetermined intervals of time or on the base of prescribed criteria aimed at reducing the probability of failure or the working deterioration of the element
Predetermined Maintenance is a preventive maintenance carried out in accordance with established intervals of time or number of units of use but without previous condition investigation
Conditioned-based maintenance is a combination of condition monitoring and/or inspection and/or testing, analysis and the ensuing maintenance actions
Predictive Maintenance is carried out following a forecast derived from repeated analysis or known characteristics and evaluation of the significant parameters of the degradation of the item
Conditioned- based
Urgent
Deferred
Predictive
Scheduled

10. ABB SACE Maintenance Portfolio Preventive and Scheduled Maintenance - PMP
Reduce the risk of failure and working deterioration of the low voltage circuit-breakers installed in the plant
It is structured in a cycle of three maintenance interventions:
1st-2nd intervention: Ordinary Maintenance
Maintaining the original integrity of the product:
Maintaining or restoring the efficiency of the products
Containing the normal deterioration of use
Guaranteeing the useful life of the product
Facing accidental events
3rd intervention: Extraordinary maintenance
Extend the useful life and/or improve:
efficiency
reliability
productivity
facility of maintenance and inspection
All interventions are carried out by chief skilled technicians
1st-2nd intervention: ordinary maintenance in order to maintain the conservation state obtained with the previous intervention and to contain the wearing trend of the apparatus:
3rd intervention: extraordinary maintenance in order to control the condition of the apparatus and re-establish, as much as possible, the original state;

11. Extraordinary Maintenance
ABB SACE Maintenance Portfolio Preventive and Scheduled Maintenance for Emax
Ordinary Maintenance
Extraordinary Maintenance
Provides systematic and functional means of maintaining a specific breaker
Each ABB ACB series has its own schedule which is based on years of experience and knowledge of manufacturing and maintaining circuit breakers

12. ABB SACE Maintenance Portfolio PMP: Benefits
Circuit breaker efficiency/reliability preservation
Guaranteeing the plant & people safety
Probability of unwanted shut-downs reduction
Providing the best management of maintenance costs
Direct costs: Direct maintenance : technicians, spare parts…
Indirect costs: non-production, accident, failure, maintenace management, …
Customer support during all product life phases
ABB professional competence guaranted:
Preventive maintenance to increase: performances, reliability, availability of circuit breakers and systems

13. ABB SACE Maintenance Portfolio Summary
Maintenance management maximizes the value of circuit breakers and customers investments.
All the circuit breakers have aging and wearing in components: a proper preventive maintenance is required
Maintenance schedule specifies the recommended maintenance actions for preventive maintenance
