Claim Text:
1. A power measurement transducer for a conductor having a current and a voltage to be measured, the measurement transducer comprising: a lower housing enclosing a lower pole piece; an upper housing enclosing an upper pole piece, said upper pole piece and said lower pole piece enclosing a conductor to be measured, said upper pole piece and said lower pole piece having faces which are in contact with each other when closed, said lower pole piece and said upper pole piece thereby forming a magnetic circuit when in contact with each other; a winding coupled to said magnetic circuit; an eccentric conductor support for positioning a conductor enclosed by said lower pole piece and said upper pole piece to within a piercing region of the eccentric conductor support; at least one piercing pin positioned beyond a conductor axial extent of said lower pole piece or said upper pole piece, said piercing pin positioned to penetrate through an aperture in said eccentric conductor support proximal to said piercing region and into an enclosed conductor supported by said eccentric conductor support; where said piercing pin is adjustable and includes threads which engage with matching threads coupled to either said lower housing or said upper housing.
