Tailored design Let’s be clear right from the start: the GEAFOL Basic represents an evolution, not a revolution. It’s based on nearly 50 years of proven GEAFOL technology and quality, but it offers numerous innovations that have allowed us to provide it with several very special characteristics. Its design takes several requirements for special applications into account which we wouldn’t have dared to dream of when the original GEAFOL was being developed. As a result, for example, the GEAFOL Basic distribution transformer with a maximum rated power of 3.15 MVA is almost ten percent lighter than a comparable model from the proven GEAFOL series. And this “slimming down” also positively affects the dimensions. Universal use The highest safety requirements must be met whenever distribution transformers are operated in the direct vicinity of humans. GEAFOL Basic distribution transformers are the perfect solution in this case, because their proven GEAFOL design is coupled with proven operational reli ability and a long service life. What’s more, they’ve got the seal of approval because all GEAFOL Basic distribution transformers meet the specifications of VDE 0532-76-11/ IEC 60076-11/DIN EN 60076-11, DIN EN 50541-1. On request, other standards, such as GOST, SABS or CSA/ANSI/ IEEE, can also be taken into account. Our GEAFOL transformers are always also tested by UL/CSA/TÜV. They meet the highest requirements for safe installation in residential and work environments with Climatic Class C2, Environmental Class E2 and Fire Classification F1. Optimum compromise Keeping the distance between the distribution transformer and consumer as short as possible considerably reduces both the complexity of the electrical network and losses in the transmission and distribution of energy. Frequently, however, there is often a shortage of space in the vicinity of the consumer. The GEAFOL Basic distribution transformer represents an optimum compromise between performance, safety and small dimensions. In addition, the high degree of standardization ensures the best possible cost-benefit ratio. Thanks to their compact shape and comprehensive safety certification, GEAFOL Basic distribution transformers can be used in almost every environment. Further development of proven technology With approx. 100,000 transformers in use worldwide, essential parts of the GEAFOL technology have already proven themselves over the long term. These include the strip winding and foil winding made from aluminum, which we adopted without change for the new GEAFOL Basic in order to ensure reliability and a long service life. In return, the mechanical design and high-voltage wind ings underwent a re-design in order to make them lighter and smaller as a truly clean solution. As a result, it was possible to considerably improve heat dissipation. With fewer horizontal surfaces, less dust is deposited, which leads to a further reduction in the already minimal time and effort needed for maintenance and also increases operational reliability. 3 Thanks to its technical characteristics, the GEAFOL Basic is well suited to a large number of applications. And you don’t have to take the limitations of classic transformer technology into account when planning. Use in a load center allows optimum network designs to be realized – with corresponding advantages in terms of cost and efficiency. In addition, the GEAFOL Basic makes it possible to dispense with special safety precautions, such as coolant collecting troughs. And with its small dimensions, the GEAFOL Basic permits more power to be installed in the same space. On request, GEAFOL Basic transformers can also be designed for converter loads and particular mechanical stresses (GEAFOL Basic+). Everything that’s needed for the future The GEAFOL Basic is also setting new standards when it comes to being prepared for the future. Even though the end of its service life is still a long way off, the GEAFOL Basic already has the perfect answer to the question of recycling. All metal parts as well as the cast resin can be recycled in an environmentally friendly way. EU guidelines: Ecodesign Directive of the European Commission Effective July 1, 2015, transformers that are installed within the European Economic Area (EEA) must meet the ecodesign requirements of the new directive, provided that they fall within the scope of the directive. Since the directive is a measure to implement Ecodesign Directive 209/125/EC, the CE mark is used as evidence of compliance. GEAFOL Basic transformers are designed accordingly and are particularly low-loss and economic. GEAFOL Basic – the intelligent further development of an excellent technology. Regardless of the application, a low weight, small dimensions and high operational reliability with the lowest possible maintenance make the GEAFOL Basic the first choice. 4 The GEAFOL Basic – Overview of features and advantages •• Innovative clean design •• Power range up to 3.15 MVA and voltages up to 36 kV (medium-voltage) or 1000 V (low-voltage) •• Certified in accordance with VDE 0532/IEC 60076-11/ DIN EN 60076-11, DIN EN 50541-7 •• Variants available for converter operation (GEAFOL Basic+ on request) •• Loss-optimized designs taking into account Ecodesign Directive 2009/125/EC for installation within the European Economic Area •• Mechanically reinforced designs available (GEAFOL Basic+ on request) •• Climatic Class C2, Environmental Class E2 and Fire Classification F1 •• Up to approx. 10 % lower weight •• Maintenance-free windings embedded in moisture-proof, fire-resistant and self-extinguishing insulating material that is suitable for the tropics •• Up to approx. 30 % increase in power possible through forced-air cooling •• Proven GEAFOL technology and quality •• Optimum compromise between size and power Built-in safety The coils of the high-voltage winding of the GEAFOL Basic are manufactured from aluminum foil. This foil winding combines simple winding techniques with high electrical safety, as its insulation is subject to less electrical stress than other types of windings. While in the case of a con ventional round-wire winding, the turn-to-turn voltages amount to double the voltage between layers, in the case of a foil winding no more than the simple turn-to-turn voltage occurs, because in this case each layer consists of one turn. This results in great power frequency voltage strength and impulse strength. In addition, the epoxy-resin vacuum casting of the high-voltage windings is performed at a high temperature, which avoids hazardous entrapped gas and allows for a high level of freedom from partial discharges up to twice the rated voltage. A high level of process exper tise guarantees excellent product quality, which is reflected, among other things, by an excellent MTBF Index. •• High electrical safety thanks to foil winding •• Freedom from partial discharges up to twice the rated voltage •• Standardized accessories Using vacuum switches with GEAFOL transformers Transformers are the key operating elements at hubs in the distribution system. Switches must control the switching of distribution transformers reliably and safely, with no need for overvoltage protection. An important parameter in transformers is the magnetization current, one of the “small inductive currents.” Interrupting these currents naturally creates marked transients, but no unacceptably high switching overvoltages that would pose a threat to connected distribution transformers are permitted. Extensive trials using a combination of Siemens GEAFOL transformers and vacuum switches have proven that the GEAFOL medium-voltage windings can handle switching overvoltages with no difficulty – providing further proof of their high product quality and operational safety. Reliable design The conductive material for the low voltage strip winding is also made of aluminum, with the width of the aluminum strip practically equivalent to the length of the coil in order to considerably reduce the axial short-circuit forces in the transformer. It’s these characteristics that make the design of the GEAFOL Basic possible. The conductive and insulating materials are bonded to each other by heat treatment and form a compact unit that also reliably handles radial forces.

Ue = 250 V Ie = 3 A AC 15 With a 25 percent increase in power rating, for example, the short-circuit losses given in the list are increased by about 56 percent, and the short-circuit voltage increases in linear fashion by 25 percent.

In the case of static converter transformers, the core tem perature is monitored additionally. The most cost-effective solution is monitoring with PTC thermistor detectors and trip relay without temperature indication. Every GEAFOL transformer is equipped at least with a PTC thermistor detector loop for tripping. Function Temperature monitoring with PTC thermistors: If two sensor systems are used to monitor temperature, one is wired up to give an alarm and the other to switch off the transformer. The nominal operating temperatures of both systems differ by 20 K. A third system can, for example, take over control ling of the fans. The temperature sensors function as resistors. If the response temperature of a sensor is reached, the resis tances rises sharply and the trip relay switches over immediately. If the winding cools down by about 6 K below the operating temperature, the relay coil in the trip relay is fully energized and the contact switches back. The ambient temperature of the trip relay is limited to 55 °C. It is therefore suitable for installation in mediumor low-voltage distribution cabinets. *) Accessories upon request 12 Standard housing Installation Protection class Indoor Indoor IP00 IP20 IP23 IP23D IP23DW A B C D E ● ● ● ● 14th character of order no.
