ABSTRACT:
The low-voltage winding of a line transformer consists of a foil winding. In order to tune the line transformer to the third or the fifth harmonic, the coupling factor is adjusted by sliding the high-voltage winding with respect to the low-voltage winding. The length of the leg of the core whereabout the low-voltage winding and the high-voltage winding are arranged substantially exceeds the width of the low-voltage winding. The high-voltage winding can be partly slid beyond the head face of the low-voltage winding, with the result that the coupling factor is reduced.
