INNOVATION AND DIGITIZATION
Getra is in continuous development. Recently to implement the technologies of the Getra Power and Getra Distribution factories, the Group invested more than € 14.000,000. The investment involved:
- Extension of the total area from 35.000 m² to 46.000 m²
- Expansion of the covered area from 12.000 mq to 17.000 mq
- Extension of the external areas
- New steam phase plant, from 600kW, 15mx6mx6m
- Movement systems for high power transformers
- Requalification of existing plants
- Oil farmer with a capacity of 500 tons
- New tank production area
In Getra Distribution plant based in Pignataro Maggiore, the industrial group has invested in the construction of robotic islands.
The installation consists of an automatic line that prints, welds and folds the sheets for the construction of the corrugated walls. The process takes place in a totally robotic way and piloted by numerical control systems and manipulation robots.
The components of the transformers are loaded onto a conveyor that is almost 100 meters long. The plant carries out degreasing, washing, drying, painting and drying during the crossing inside special tunnels. Subsequently, the installation cuts the steel sheets using a high definition plasma, a manipulation robot picks them up, bending all the components according to the project and stacks them on platforms ready to be transferred to the next processing island.
Recently, Getra invested in the revamping of the Getra Power based in Marcianise. The advantages deriving from the replacement of the lighting system with LEDs are:
- Improvement of working conditions by providing an appropriate level of lighting
- Reduction of CO2 emissions
- Zero maintenance costs
- Reduction of electricity consumed
With an investment of over € 20.000,000 in the Getra Power factory, based in Marcianise, the Group has recently designed and built a new Test Bay with the aim of carrying out routine tests and special tests to verify the correct operation of power transformers.
Characteristics of the new Test Bay:
- Totally shielded and soundproofed, free from electromagnetic and acoustic interference
- It allows to test two high power transformers at the same time
- Allows you to test transformers up to 1.000kV
- It is equipped with a universal transformer loss measurement system for testing transformers up to 1.000kV
All supported tests are performed in accordance with IEC 60076 and in compliance with safety standards.
Getra implemented an investment plan by allocating part of its investment to the Winding Department. The Group pays particular attention to the construction of the windings, to the control of the conductors and to the choice of the insulating materials used.
Characteristics of the Winding Department:
- Totally new segregated clean area for horizontal and vertical wrapping machines
- 6 horizontal and 6 vertical machines, 4 weighing systems and 2 drying ovens, 30 tons of air cushions for the management of the Transformer and 4 overhead cranes up to 32 tons
- The windings are made with electrolytic copper conductors
In the Getra Power factory, based in Marcianise, the industrial group has invested over € 2.000,000 in the construction of a new line of large carpentry.
The purpose of the company was to create a new production line by purchasing a series of useful machinery to optimize the process making it 100% integrated and with a view to industry 4.0 and sustainability.
The benefits deriving from the construction of large carpentry are numerous. The first is the integration between the engineering department and the production process with the consequent optimizations in terms of reducing the use of materials. Secondly, the import of large and bulky materials that often come from distant suppliers is reduced and this implies an improvement in terms of sustainability.
Characteristics of the carpentry:
- Extension of the total area
- Space optimization with the inclusion of Cantilever for sheet metal storage
- Assortment of new machinery: plasma cutting machine, CNC synchronized press brake, CNC drilling / milling machine, electronic synchronized roller calender, CNC lathe with C axis and Y axis motorized tools, 400A inverter MIG welding machines.
PARTNERSHIP WITH OUR CUSTOMERS
In collaboration with Enel, the Getra Group has produced the Jolly Mobile Transformer that is installed in the event of an emergency to replace faulty equipment. Designed and built to be transferred to the destination sites without resorting to exceptional transport, the transformer can be installed in any electrical distribution substation and can be delivered in Italy within 4/8 days from the emergency call.
The three-phase transformer 100MVA – 220/20.8-20.8kV, produced in collaboration with Enel, was born from the need to actively participate in the implementation of a radical reclamation and an important strengthening of the electrical distribution system in the San Giovanni area in Teduccio, the eastern district of Naples.
The project involved the construction of a three-winding transformer, one primary with two sections in parallel and two separate secondaries, both arranged on two superimposed levels contained in the same box with a double advantage: both economical and space-saving, having only one stall . The transformer was designed and produced with an intermediate yoke core and has a substantially similar behavior to two distinct half-power transformers, connected to the same primary busbar and with primary regulation in common but with two separate secondary busbars. The presence of the intermediate yoke guarantees an independent electromagnetic operation of each secondary winding, in other words the disturbances of a secondary network are not perceived by the other.
This project has given Getra the opportunity to gain high-profile experience on a fundamental technology in applications for which the coupling of the transformer with power rectification machines is envisaged.
The Getra Group is constantly committed in identifying the requirements and enabling technologies aimed at modernizing the traditional electrical substation.
The project that involved the realization of the Smart Trafo equipped with a voltage regulator under load and a control cabin, was used to conduct studies in order to develop a control, monitoring and diagnostics system based on the wavelet method to identify the non-periodic oscillations and genetic algorithms as an optimization technique.
The transformer was used to define, simulate and test the architecture of a Distribution Management System (DMS) that processes and implements the necessary control actions in the case of incipient phenomena that could occur, thus avoiding potential out of services with consequent supply interruptions. for powered users.
The project for the construction of the Smart Trafo was based on the process that passes through the characterization and modeling of an innovative electrical substation inspired by the criteria of smart grids and environmental protection. The objectives:
- Renew the distribution networks;
- Allow an active role for the electrical load;
- Provide information, services and power of choice to the consumer (active user);
- Increase the degree of reliability and safety of the electrical system;
- Reduce the environmental impact of the entire electrical system.
