Preventive Maintenance – PMP

MaintenaceAgenda

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

Maintenace theoryAim: Mind-changing

‘’Any maintenace activity is a cost’’

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

Maintenace TheoryMyths & Facts

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.

Maintenace TheoryWhy maintaining

Direct 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

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

ABB SACE Maintenance PortfolioPreventive and Scheduled Maintenance - PMP

Reduce the risk of failure and working deterioration of the low voltage circuit-breakers installed in the plantIt 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

Ordinary Maintenance Extraordinary Maintenance

ABB SACE Maintenance PortfolioPreventive and Scheduled Maintenance for Emax

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

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

ABB SACE Maintenance PortfolioPMP: Benefits

ABB SACE Maintenance PortfolioSummary

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
