Innovation applied to the digitisation of the energy sector

Electrical instrumentation for power grids, substations and Smart Grids

The energy sector is evolving towards more and more efficient infrastructures. digitised, connected and geared to operational efficiency. The integration of renewable energies, the electrification of industry and the development of Smart Grids require advanced systems for metering, monitoring and management of electrical energy.

Modern power grids need equipment capable of capture reliable electrical data, monitor network status and facilitate operational decision making. The digitalisation of energy infrastructures makes it possible to optimise maintenance, improve the quality of supply and increase the efficiency of the electricity system.

SACI participates in this technological evolution by developing electrical instrumentation, network analysers, instrument transformers and energy monitoring solutions used in transmission and distribution networks, electrical substations, transformer stations and generation plants.

Measuring equipment and solutions for transmission and distribution networks

The electrical substations are key installations within the electricity system, responsible for adapting the voltage levels necessary for the transmission and distribution of energy.

Its main function is to transform the voltage levels between the different stages of the power grid, allowing large amounts of energy to be transported efficiently and safely.

Depending on their role within the network, they are mainly distinguished:

• Geared substations, which reduce stress to levels of medium voltage, generally between 10 kV and 66 kV, for distribution.

• Lift substations, located close to the generation plants, which raise the voltage to transport levels such as 132 kV, 220 kV or 400 kV.

These installations require reliable electrical measurement, protection and monitoring, The network status can be monitored, system stability can be guaranteed and remote management of the infrastructure can be facilitated.

SACI supplies current transformers, power analysers, instrumentation, instrumentation and measurement converters used in substations, including tailor-made solutions adapted to particular electrical specifications or space constraints in switchboards.

Monitoring and control in electricity distribution networks

The transformer substations (CT) are installations designed to transform energy from low to high energy levels to high energy levels. medium voltage to low voltage, The use of the product in the production process is a key factor in its safe distribution to the final consumers.

They usually receive energy at levels of 10 kV, 15 kV, 20 kV or up to 30 kV and transform it to 400 V in three-phase systems or 230 V in single-phase systems.

In this type of installation it is essential to have electrical measuring equipment capable of monitoring network behaviour, The aim is to detect incidents and optimise the management of the supply.

SACI solutions allow the integration of electrical instrumentation, instrument transformers and communication systems within energy monitoring architectures used in distribution networks.

Electrical instrumentation for power plants

Renewable energies are based on the use of natural resources such as the sun, wind or water to generate electricity in a sustainable way.

Technologies such as photovoltaic solar energy or the wind energy have become key components of today's energy system. These installations require electrical monitoring systems that are capable of controlling plant performance, monitoring grid quality and analysing the behaviour of power generation.

SACI is involved in renewable generation projects by supplying mains analysers, current transformers, voltage transformers and digital instrumentation used in the electrical monitoring of photovoltaic plants and other generation facilities.

This equipment makes it possible to obtain accurate information on electrical variables such as voltage, current, power or energy, This will facilitate the optimisation of the operation of the installations.

Smart grids and data management

The Smart Grids represent the evolution of electricity grids towards systems capable of monitor, analyse and manage energy in real time.

These networks integrate electrical engineering, telecommunications and data acquisition systems, The new generation system will improve the operational efficiency of the electricity system and facilitate the integration of distributed renewable generation.

The energy monitoring in Smart Grids allows:

• monitor the state of the electricity network
• improving the quality of supply
• optimising energy management
• integrating renewable generation into the grid

SACI solutions allow you to deploy measurement and data acquisition architectures for smart grids, integrating network analysers, instrument transformers and electrical instrumentation into energy monitoring systems.
