<p>An inductive sensor of alternate current, preferably for use in an electronic current meter basically consists of two coils (1,2) containing each two windings, one winding for current measurement and another serving as a static armour of the first winding, whereby both coils (1,2) are positioned on a printed circuit board (3) that can be independent or part of a printed circuit board of a large electronic assembly and function as a secondary winding of the sensor. The sensor of the invention is characterized in that a primary winding (4) is of such shape that its free ends are adapted to various types of connectors (DIN, BS, ANSI) of electronic electricity meters, whereas the central part of the primary winding is shaped in a way that it at least partially embraces both coils (1,2) in a relatively small distance or runs between them. <IMAGE></p> |
