ABB SACE Maintenance Preventive Maintenance Program Feb 2013 ABB SACE Maintenance Preventive Maintenance Program

Maintenace Agenda Aim Mind-Changing Why maintaining Miths and Facts Estimated lifetime ABB SACE Maintenance portfolio: Maintenance with ABB SACE: Benefits Offer: Preventive Maintenance – PMP

‘’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

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. FALSE FALSE FALSE

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

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

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

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

ABB SACE Maintenance Portfolio Preventive maintenance Before a failure Preventive Maintenance Predetermined Maintenance Conditioned-based Maintenance Scheduled Maintenance Predictive Maintenance LEAP+PMP PMP

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;

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

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

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
