Alstom Grid

Creation date: 1^st of November. 2012

Alstom is an International Company with head offices located in France. Alstom Grid is one of Alstom's three divisions.

Range of products

With strong references up to 800 kV and 2750 MVA in major power networks worldwide, Alstom Grid is one of the world leaders in the manufacturing of electrical power transformers and reactors. As a pioneer in this field, our expertise in electrical power transformers extends to all levels, from generation to HVDC systems and all kind of special industrial applications.

A world leader in electrical power transformers for over 100 years.

Alstom Grid can count on thirteen dedicated facilities on four continents for producing power transformers and a current production capacity of more than 130,000 MVA. This global manufacturing footprint, coupled with efficient technology transfer programs, enable us to offer the most adapted solution - for every need, everywhere and with the same top class level of quality.

Our intensive research into new products and solutions drives the process of continuous improvement. As proof of the technological leadership of Alstom Grid, our experts actively participate in internationally renowned workgroups and conferences.

From low to extra-high voltage, small to very large power ratings, standard to the most complex designs: Whatever you need, we have the right solution.

A comprehensive range of electrical power transformers for all needs :

Rectifier Transformers

A complete range that fits your rectifier:

• 100-500 V DC & up to 140 kA DC for Zinc, Copper and Chlorine electrolysis,
  
  
• 450-1600 V DC & up to 110 kA DC for Aluminum electrolysis.

Electrical Arc Furnace Transformers (EAF)

Arc furnace transformers deliver high currents over a wide range of voltages. While power ratings between 10 and 300 MVA and secondary currents of more than 100 kA are quite common, EAF transformers are precisely adapted to the extreme thermal, mechanical and dielectric constraints of the furnace load cycles.

MS 3000 Transformers' monitoring system

After more than 10 years of experience in transformer monitoring systems, and following the acclaimed MS 2000, Alstom Grid has just launched the MS 3000 online condition monitoring and expert system.

This new generation offers innovative features like dissolved-gases analysis (DGA), a built-in simulator and expert system software that provides data and recommendations on transformer operation and maintenance. It also allows multiple transformers to be managed with only one system.

Like its predecessor, the main features of the MS 3000 include a user-friendly operation interface, the possibility of adaptation to both new and existing transformers from any manufacturer, and a wide range of communication protocols now including the IEC 61850 standard certified by KEMA.

Green Power Transformers offering

Environmental concerns and energy efficiency take more and more importance day after day. Alstom Grid has developed a wide offering of green solutions for power transformers ranging from 10 to 200 MVA and ratings up to 245kV. These eco-efficient transformers are designed with one or more of the following functionalities according to your request:

• Natural ester oil insulation
• Hermetically sealed tank
• Reduced noise levels
• Optimized low losses
• Online monitoring system (MS3000)

Alone or combined, these technologies provide concrete environmental benefits and energy efficiency with reduced pollution risks, increased fire safety, overload availability, noise and loss reduction, extended life and more.

The low-maintenance transformer : Hermetik

Hermetically sealed power transformers without oil conservator are Alstom’s field-proven answer to today’s needs. Thanks to the innovative design of the radiators, the oil expansion vessel is not needed and thus the oil is prevented from coming into contact with ambient humidity. Service life is also increased with the use of a vacuum-switch on-load tap-changer (OLTC) that eliminates contact erosion. With minimal oil and OLTC aging rate, the hermetik does not require any particular maintenance or works over its service life, speeding up the return on your investment.
