The transformer includes a soft magnetic core on which a primary winding arrangement, a secondary winding arrangement, and a compensation winding arrangement are arranged. The compensation winding arrangement is connected to a current control device which feeds a compensation current into the compensation winding arrangement using a control signal. A magnetic field measuring device measures the magnetic field in the core of the transformer or the stray magnetic field that closes outside the core via an air path and provides the control signal.

THE IMPROVED STATIC SHIELDING IS COMPRISED BY INSERTING SERIES CAPACITANCE BETWEEN THE WINDING TURNS IN A MANNER SUCH THAT THE VALUE OF A FIRST SERIES CAPACITANCE CS1 ON THE LINE OF THE TRANSFORMER IS RELATED TO THE VALUE OF A LAST SERIES CAPACITANCE CSN ON THE EARTH SIDE OF THE TRANSFORMER IN ACCORDANCE WITH THE EXPRESSION

WHEREIN K IS A CONSTANT HAVING A VALUE BELOW 0.05 AND CG1 IS THE CAPACITANCE TO EARTH OF ALL THE TURNS THE VALUES OF SERIES CAPACITANCE OF THE INTERMEDIATE TURNS BETWEEN SAID SERIES CAPACITANCE CS1 AND CSN AND ARE RELATED IN A

MANNER SUCH THAT SAID INTERMEDIATE VALUES VARY APPROXIMATELY LINEARLY BETWEEN THE VALUES OF SAID SERIES CAPACITANCES CS1 AND CSN.
