How to extend the life service of the equipment: the importance of maintenance in electro-intensive installations

Electro-intensive installations require continuous and preventive maintenance, with the aim of maintaining equipment at its optimum performance and anticipating failures, both to make the most of their useful life and to optimize operational efficiency and create efficient responses to unplanned shutdowns and inconveniences of all kinds.

The availability of equipment in industrial installations, in generation or distribution of electrical energy is essential for the operation of these electro-intensive installations. In practice, any setback or unplanned downtime means economic losses and other inconveniences that can significantly harm the industry’s activity.

To avoid this, in addition to regular maintenance, it is possible to anticipate some known or very likely failures. A predictive maintenance is complex and may require several parameters and monitoring that in practice can make it inefficient or require changes in the installation to take measures that imply additional investments and changes.

For example, components whose use is affected by duty cycles, temperature, voltage, etc., would – at least theoretically – require a measurement of these parameters, which can be highly variable depending on the installation. For example, a photovoltaic generation installation may have different duty cycles depending on cloudiness, which could affect the lifetime of electronic or mechanical components.

However, it is possible to anticipate some failures efficiently without the need for complex measurements. The lifetime of some components is known in advance – although the lifetime may vary depending on the above, in practice it is cost-effective and easy to anticipate failures based on the lifetime measured in hours, as is the case for example with capacitors, both AC and DC.

Advantages of maintenance of critical components to extend the lifetime of electro-intensive installations

Therefore, from ZGR Corporación, we recommend a change of critical components before the estimated useful life ends, as this has several advantages:

  • Extending the useful life of the installation. While critical components have a useful life, between 6 and 8 years, most of the generation, industrial or electricity distribution facilities expect a much longer useful life of their equipment.
  • Ensure the availability of the installation. Planning component replacement work makes it possible to carry out this work at times of shutdown or when it is most convenient for the installation. The risk of not doing it is to have a shutdown or unavailability at any other time.
  • Cost savings. In addition to the savings in guaranteeing availability, savings are also relevant for the rest of the components that could be affected in the event of a breakdown. Capacitors, when they reach the end of their useful life could burst, causing damage not only to those components but also to the other elements in the equipment that could be affected such an explosion.

ZGR technical service

To assist its customers in the operation of their electro-intensive installations, ZIGOR offers a critical component replacement service. Thanks to the modularity of its equipment, it is possible to remove parts of the equipment (power modules), temporarily replace them with others to ensure the continuity of the equipment’s operation, and replace the critical components in the removed module, to put it back into service at the appropriate time.
