MV supply of significant single-phase load
GBE solution to those situations where significant singlephase loads are generated from a threephase network, are proposed with the design and manufacture of two different types of transformers that evenly distribute the current and the power on the three phases:
The three-singlephase solution, that is easier and cheaper than the SCOTT-T, consists in transformers designed and manufactured according to the below diagrams, which distribute even not symmetrically, the load on the three phases. Unlike the SCOTT-T, the three-singlephase transformer does not require two balanced singlephase loads, but it may work with any type of load.
It is clear from the above diagrams that the current in the primary central phase is twice that of the other two phases, whereas the current in the secondary windings is identical and exactly the same as the one supplied on the load.
GBE have recently supplied a series of three- singlephase cast resin transformers to be installed in Germany and in Spain.
Offshore and onshore, an exclusive product for all types of marine installations Transformers and reactors for marine applications are distinguished in two different types of installations: offshore and onshore. For each of these installations, additional distinctions can be made depending on the application and use. GBE develops these exclusive products in cast resin, dry type […]
GBE celebrates 20 years of business. We have achieved excellent results thus far, but we’re not done yet. There are numerous projects currently under way – not only in terms of the production process, with new investments especially in the power division – but also in regards to certifications in new markets where specific […]
Tripled production capacity for power transformers GBE produces air-insulated, cast resin and oil-filled, special and distribution transformers and reactors. In recent years we’ve increased the number of units produced for each type of transformer and reactor, as well as the average power, following an increase in orders for the power division, which is steadily […]
