Services to meet your needs

1. Preventative Maintenance

   • Inspect regularly. 
   • Keep essential parts cleaned and well lubricated.
   • Test periodically.
   • Use the right tools and consumables.

   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: 

   • Checks the preservation and efficiency status of apparatus.
   • Anticipates the trend of deterioration of products, signalling the need of replacement for excessively worn-out components, where available, or suggests alternative solutions for bringing them up to date.

   Preventive Maintenance creates value over the long-term by:  

   • Improve equipment efficiency minimizing the failures in production.
   • Less expensive direct costs of maintenance, by reducing the charges due to urgent situations.
   • Less expensive indirect costs of plant shutdown, taking advantage of the scheduled stop.
   • Ensuring better efficiency and reliability of the plant.
   • Guaranteeing the plant safety for a longer time.
   • Extending the product’s life.

2. Time Based

   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. 

3. Condition Based Maintenance

   Based on real time data, with the help of constant monitoring equipment (eg: sensors), this maintenance is carried out only when one or more conditions exceeded a threshold considered a degradation value.

   When the threshold is reached, a warning or alarm is sent, and maintenance should be carried out.

   With Condition Based Maintenance it is possible to turn on a signal locally or remotely when there is the need for maintenance.
   
   

   ABB offers 2 solutions for local monitoring and diagnostic:

   1. For Low-voltage ABB has integrated it in ABB modern and advanced trip units (embedded trip units like Ekip Touch and Ekip Hi-Touch and external relay Ekip Up+). In both cases it is possible to evaluate the mechanical life counting the number of operations and it is possible to read 3 temperatures in key points just adding Ekip signaling 3T module.
      
      
   2. For Medium-voltage circuit breakers there is SWICOM, a dedicated unit which provides mechanical and electrical health status of a fleet lineup. It acquires data communicating with IEC 61850 based protection relays and converts it to diagnostic information. SWICOM can communicate with additional sensors to have further asset information. One SWICOM unit handles a whole switchgear lineup and even up to 24 panels. It can be installed on ABB and non-ABB medium voltage assets.

4. Predictive Maintenance

   Accessing to ABB Asset Manager it's possible to monitor the heath conditions of the main components of the switchgears and circuit breakers. With the Predict function activated, it's possible to understand the day-by-day health status and optimize the maintenance needed before the fault happens.   
   
   The Predict feature considers in its algorithm: the age of the product and its components, the environmental and utilization conditions, their modification in the years, and the maintenance already performed (parts replaced, maintenance activities and tests performed). The output is the indication of the next maintenance date and a simple evaluation of the health conditions and risk of fault (green= good, yellow= medium, orange= bad, red= very bad). With Predict, the time between one activity and the next one is not fixed as it is influenced by the events (trips, n. of openings, environmental conditions, maintenance performed).

5. Reactive Maintenance

   When a fault happens and when it's possible to correct it, ABB offers Corrective Maintenance. A customer can call their ABB local service team to plan the time and day of the intervention. ABB has expert field service engineers to support their customers, solving problems and suggesting how to prevent similar events.
