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 Predictive Maintenance -LEAP

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

Maintenace Theory Why maintaining Direct costs Direct Costs • Maintenance: personnel, materials Indirect/induced Costs: Indirect 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 in market share

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
