1. A current sensor comprising:
a flexible printed circuit board including:
a first layer;a second layer coupled to the first layer; anda third layer coupled to the second layer, wherein the second layer is disposed between the first and third layers, and at least one of the first, second, or third layers is pivotably coupled to another of the first, second, or third layers; and a Rogowski coil including:
an outer coil having:
an upper portion disposed on the first layer of the flexible printed circuit board and defining a first opening therethrough; anda lower portion disposed on the third layer of the flexible printed circuit board and defining a third opening therethrough; andan inner conductor disposed on the second layer of the flexible printed circuit board and defining a second opening therethrough, the first, second, and third openings each configured to receive at least one active lead therethrough, wherein the flexible printed circuit board is movable between a first configuration, in which the first, second, and third layers are disposed in the same plane, and a second configuration, in which at least one of the first, second, or third layers is disposed at an angle relative to another of the first, second, or third layers. |
