  • Line-mounted electrical energy measurement device with integrated voltage pickup and clamp
    Patent number: 9500684
    Abstract: A tap assembly for a measurement device has a clamp base, a main assembly, a piercing member, a clamp member defining an anchor surface, and a bolt member defining a shaft portion and a head portion. The clamp base has a brace portion defining a bolt opening. The piercing member is supported by a contact plate of the main assembly. The clamp base is attached to the main assembly to define a clamp notch. The contact plate is adjacent to the clamp notch. The shaft portion of the bolt member extends through the bolt opening and engages the anchor surface. At least a portion of the conductor is arranged within the clamp notch between the clamp member and the piercing member such that axial rotation of the bolt member displaces the clamp member towards the piercing member to cause the piercing member to engage the conductor.
