The invention relates to a continuously adjustable power unit,
designed to supply the voltage needed by some testing
installations from the electrical equipment laboratories. The
solution consists from a two columns magnetic core, having
placed on one of the column a primary winding divided into two
immobile semi-coils, serial between them and placed at the ends
Description of the column; on the same column is positioned a secondary,
moving, coil, connected in short-circuit.
Applications: The power unit can be used to supply the voltage
needed by some testing installations from the electrical
equipment laboratories.
Advantages: The power unit increases the electrical operating
safety and is leading to the improvement of the electro security
conditions.
