ABB:s högspänningsgenerator, den. s.k. Powerformer, genererar elektricitet med tillräckligt hög spänning för att den ska kunna ledas direkt in på elnätet, utan
Powerformer(R), a new high-voltage generator, was presented by ABB. It offers a direct connection to the power network without the need for a step-up transformer. In a sense, Powerformer incorporates into one unit the functions of both the conventional generator and the step-up transformer.
READ PAPER. Powerformer- A Discontinuous Innovation. Download. Powerformer- A Discontinuous Innovation. The general concept of Powerformer/sup TM/, a high voltage generator connected directly to the grid, is described. By using high-voltage cable technology it is possible to confine the electrical field to inside the winding and reach high voltage levels on the generator terminals. The prototype high-voltage generator rated at 45 kV, 11 MVA has been operating since spring 1998.
In this paper, the expressions of power characteristics with excitation regulator and power limit of Powerformer are deduced. Combining with the parameters of Powerformer prototype and conventional synchronous generator, the power characteristics variation of Powerformer Based on the analysis of the relationship between the terminal voltages and the reactive power of a generator, the shortcomings of the available scheme to protect generators in parallel from overvoltage have been pointed out, and a novel overvoltage protection scheme is put forward. For machines connected directly to busbars, especially for powerformers, a novel type of high voltage generators Many well-known innovations and discoveries, both modern and historical, have Swedish origins. This book presents technical products and methods which represented a sufficiently high degree of Powerformer är en generator utvecklad av ABB på 1990-talet och slutligen lanserad 1998.

Powerformer is a high-voltage generator; the limitation in its rated voltage is set solely by the AC Power cable and the cable accessories (terminations and joints) used in its stator winding. This means that Powerformer of voltage ratings up to 400 kV can be realized, although has not been proved yet.
The Powerformer can generate electricity at voltages between 20 kilovolts (kV) and 400 kV. generatorn är baserad på Powerformer™ teknologi [3,4,5] med en permanentmag-netiserad rotor med variabelt varvtal, som är direktansluten till turbinen. Den lågfrekventa spänningen (> 20 kV) från generatorn är omvandlad till likström via dioder. Vindkraftverken kopplas ihop i grupper, där överföring av effekten sker Abstract: Powerformer(R), a new high-voltage generator, was presented by ABB. It offers a direct connection to the power network without the need for a step-up transformer.
The Powerformer — which can generate at high voltage, feeding electricity directly into the transmission network without the need for a step-up transformer — will be installed at Höljebro hydro power plant on the Ljusnan river.

Alright so here is what I am looking for. I need a small generator that could fit inside of a box-fan. I've seen things about stepper motors and all but I need the absolute most simple generator you can come up with. I'm no electrician and

Installing Powerformer in Höljebro, together with the environmental benefits of the high voltage cable technology applied in the generator, will give a saving equivalent to a value of US$1.7M. The Swedish National Energy Administration is also backing the installation in Höljebro by providing Fortum Kraft with support for the project.
