Infrastructures & Energy

High-performance protection for large critical applications

Transport, energy and water infrastructures are fundamental to carrying out the activities of countries, cities, companies and people.

 

Our professional and personal wellbeing largely depends on their proper functioning.

And to ensure that they do, it is necessary for the energy supply that powers all of these infrastructures not to be disrupted by any electrical disturbance.

 

Because what would happen if air traffic control radar lost its electrical supply? Or if traffic lights did?

If there is a sector that due to its functioning could affect both our day-to-day wellbeing and the competitiveness of our professional work, it is undoubtedly that of infrastructures.

 

Airports, railways, ports and roads in transport infrastructures; electricity and fuel networks in energy infrastructures; and drinking and drainage water networks in water infrastructures constitute a collection of facilities, networks and services that are extremely critical to society. For this reason, and for their ability to influence the carrying out of other activities, they need a continuous and stable power supply, a supply that does not experience interruptions that affects normal operation.

Main electrical disturbances

A wide range of electrical disturbances, as diverse and varied as the infrastructure sector itself, can affect normal operation. In addition to voltage drops and losses in the conventional distribution system, the adverse climatic conditions to which this collection of infrastructures are subjected represent a serious determining factor that needs to be anticipated during planning and execution.

 

The main electrical disturbances in this sector are the following:

Spikes

Solutions

To prevent these common electrical disturbances from occurring, Salicru offers a range of advanced technological solutions at the service of infrastructures as critical as those in this sector.

 

It consists of devices that can work individually or as a complement, depending on the type of facilities to which they are connected, and offer alternating current supply continuity solutions, stability against voltage variations, control of the speed of machinery motors and adjustment of the level of voltage coming from the distribution network.

Uninterruptible power supplies (UPSs)

Salicru has developed a range of uninterruptible power supplies (UPSs) whose features are ideal for large critical applications such as transport, power and water infrastructures, as they ensure the safeguarding of equipment and the proper management of systems.

 

They are devices that are capable of storing energy in a battery of accumulators that have the ability to convert the direct current of this battery into alternating current and provide electricity without interruptions in supply.

Variable frequency drives

There are increasingly different types of facilities that need to regulate the speed of their motors in order for them to adapt to changing load needs and for their energy consumption to be reduced. Salicru’s variable frequency drives enable simple and efficient control of any application driven by asynchronous motors from 0.2kW to 500kW.

 

In the face of growing demand for energy in these facilities and also in many industrial processes, these variable frequency drives offer an effective solution to enhancing energy efficiency, producing significant financial savings and significantly improving the environment.

DC/AC systems
Ensuring the functioning of all of these infrastructures is essential for Salicru, and to achieve this, we also offer products that ensure alternative power sources, such as our DC/AC systems, devices that convert alternating into direct current (rectifiers, chargers) or direct into alternating current (inverters). They are specially designed to operate in very harsh and demanding operating environments, such as:
  • Power generation plants
  • Electrical substations
  • Oil pipelines
  • Gas pipelines
  • Petrochemical plants
  • Mines
  • Railways
  • Telecommunication facilities
  • Hospitals
  • Industrial processes
Transformers and autotransformers
Salicruĺs IT series of low-voltage electrical transformers and autotransformers are used as electrical isolation for the reduction of mains disturbances or to adjust the level of voltage coming from the distribution network. Autotransformers, with their serially-connected coils that do not provide galvanic isolation, have the function of converting one voltage to another, and, as such, are a more economical solution than transformers.
Transformers are used in different types of industry, construction, energy technology and marine applications, such as electric motors, compressors, converters, cooling systems, UPSs and IT/TN networks. And autotransformers are used for adapting the voltage of the mains supply to the voltage required to power all kinds of load and machinery.
93% of power supply problems are micro-cuts, which are easily preventable with a UPSĺ
