According to a first aspect of the invention, there is provided a coil for measuring electrical current in a conductor surrounded by the coil, the coil comprising at least one geometrically closed loop. In an embodiment, each loop comprises an incoming conductor, an outgoing conductor and an intermediate loop-defining conductor that bends round and crosses over itself. In an embodiment, the coil comprises a plurality of geometrically closed loops that are electrically interconnected. In an embodiment, the coil comprises a first loop, an end loop and at least one intermediate loop between the first and end loops, with adjacent loops being electrically interconnected. According to a second aspect of the invention, there is provided a method of constructing an electrical current measuring coil of the type described above. |
