Power electronics is a sector characterized by adaptability and flexibility, thus claiming its share in any technology application. To ensure this, FDUEG offers its experience and know-how in order to provide transformers that are perfectly compliant to any field of application.[\/vc_column_text][vc_images_carousel images=”1541″ img_size=”full” onclick=”link_no” hide_pagination_control=”yes”][vc_row_inner css=”.vc_custom_1556550758627{margin-top: -185px !important;margin-bottom: 10px !important;border-radius: 3px !important;}”][vc_column_inner width=”1\/3″]

This kind of transformers allows to create stable earth connection points, so that overcurrents induced by a fault are channeled from the three-phase power transmission line towards ground.<\/p>\n
Relevant features for grounding apparatus include mechanical stability<\/strong> (because of the high currents that may appear), a sufficiently long time constant to avoid overheating before the protection devices intervention, and a limited footprint<\/strong>.<\/p>\nGrounding transformers do not convey relevant power during a distribution system\u2019s normal operation. However, they become fundamental in case of line malfunctions. In a fault condition, the entire structure needs to be sufficiently solid and massive in order to withstand the current variation without any damage. FDUEG proposes a solution which makes use of the least possible space within the facility, while granting its security.<\/p>\n
Grounding transformers remain transparent with respect to positive and negative sequence voltages, while offering a low-impedance path to homopolar currents and third harmonics, improving the global power quality of their system. This means that, besides a power supply that remains undisturbed, the cascaded appliances are loaded less severely, resulting colder and extending their service life.<\/p>\n
FDUEG produces grounding transformers for power lines up to 36 kV<\/strong>, built on three wound columns or on five columns of which the two on either side lack a winding. Models that are insulated in air or oil are available for both setups.[\/vc_column_text][vc_column_text]<\/p>\nSpecial transformers for testing facilities<\/h3>\n
This category is the most variable with respect to the specific needs of a customer<\/strong>. Each test room or laboratory is different from others, thus requiring precise features for its operations. A transformer is essential for the current management of the power supply, and needs to be carefully designed based on duty cycle and loading profile of its actual usage.<\/p>\nFDUEG boasts numerous deliveries of its special type transformers to testing facilities with specific needs, designed to analyze and validate electromechanical switches, magnetic cores, motors or even other transformers.<\/p>\n
In particular, the following utilization categories can be distinguished:<\/p>\n
\n- Service life tests<\/li>\n
- Overload tests<\/li>\n
- Insulation tests and power frequency withstand voltage tests<\/li>\n
- No load losses measurements<\/li>\n<\/ul>\n
The offered products are solid and durable, able to effectively manage the currents and high voltages in use at the laboratory the are installed in, with any kind of service and loading profile. Each device can be equipped with transformer steps to attain a wide voltage regulation.<\/p>\n
The construction aims at the best result in performance and quality for the machine, since exploiting a power supply whose high-level output is constant in time is a crucial aspect for a testing facility.[\/vc_column_text][vc_column_text]<\/p>\n
Vector groups Dyn11 and upon request<\/h3>\n
Besides the usual vector groups, as delta – star (Dyn11)<\/strong> and vice versa, FDUEG can exploit all available solution in turns combination in order to cover any need in terms of amplitude and phase shifting of primary and secondary voltages.<\/p>\nA system in need of a nice stability in power supply, without heavy influence from third harmonics in current, while contemporarily keeping no phase shift between primary and secondary side voltage, may use the vector group delta \u2013 zig-zag (with or without neutral). In addition to the desirable properties already listed above, it has to be considered how a zig-zag transformer connection<\/strong> offers a nice rejection of star point displacement, an essential quality in case of heavily unbalanced single-phase loads.<\/p>\nIn some cases, a certain phase angle with respect to the supply is needed for the voltage output, different from the usual 30\u00b0 lagging or leading. The interval between 0\u00b0 and 30\u00b0 can be covered by transformers with phase-shifting windings, configured either as delta with appendices or as non-symmetrical zig-zag. This kind of construction may be used, without restrictions, both as primary or secondary winding of the transformer under scope.<\/p>\n
Systems without a specific need for galvanic separation might make use of the custom autotransformers produced by FDUEG. Models for continuous usage or for intermittent service can be designed upon request. A prominent application of these involves induction motor starting service<\/strong>.<\/p>\n\n\n\nT<\/em>ype<\/em><\/td>\nPower<\/em><\/td>\nFeatures<\/em><\/td>\nProtection<\/em><\/td>\n<\/tr>\n\nTransformers for converters<\/strong><\/em><\/td>\nUp to 16 MVA<\/em><\/td>\nUp to 36 kV<\/em><\/td>\nAN – AF – ANWF<\/em><\/td>\n<\/tr>\n\nGrounding transformers<\/strong><\/em><\/td>\nUp to 10 MVA<\/em><\/td>\nUp to 10 kHz<\/em><\/td>\nWF<\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1559743343528{margin-bottom: 1px !important;border-bottom-width: 1px !important;}”]<\/p>\n
