Preventive maintenance services

Performing preventive maintenance means put in place all that activities and precautions that prevent an equipment to fail: 

All that actions aimed to reduce the risk of unwanted malfunctioning: managing a planned maintenance activity is less expensive than reacting when a problem occurs. 

ABB Electrification Service offers a Preventive Maintenance Program for ABB Low and Medium voltage equipment (switchboards, circuit breakers and relays) with the aim to anticipate the failures and reduce the deterioration of the equipment and risk of unexpected shutdown.  

The program: 

Time Based Maintenance (TBM) is maintenance performed on equipment based on a calendar schedule.  

Usually, product’s manuals have time as a trigger of maintenance, eg: cars indicate to replace tyres after thousands of kilometres. 

ABB developed a maintenance program that does not consider only time but also environmental conditions in which the products work, age and maintenance already performed.  

This program is SWAPs and consists in 5 levels of maintenance: See, Watch, Act, Perform, Secure. 

Maintenance intervals are defined according to the assessment of the equipment environmental and operational conditions, age, previous maintenance performed, and presence of monitoring and diagnostic solutions. The schedule continues till the equipment reaches its end of life, also recommending the right time for relay and circuit breaker retrofit.

A time-based maintenance is a way to prioritize maintenance resources toward assets that could generate the highest risk in case of failure.
