Line-mounted electrical energy measurement device with integrated voltage pickup and clamp

摘要

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.

主权项

1. A measurement device for generating measurement data associated with at least first and second conductors of an electrical distribution system comprising:
at least first and second tap assemblies each comprising a clamp assembly comprising a main housing, a clamp base is secured to the main housing, a brace defining a bolt opening, the brace is formed on the clamp base, a piercing member supported by the clamp base relative to the brace, a clamp member defining an anchor surface, and a bolt member defining a shaft portion and a head portion, where the shaft portion of the bolt member extends through the bolt opening and engages the anchor surface such that axial rotation of the bolt member displaces the clamp member towards and away from the piercing member; and at least one cable operatively connecting the first and second tap assemblies; whereby at least portions of the first and second conductors are arranged between the clamp member and the piercing member of the first and second tap assemblies, respectively, such that displacement of the clamp member of the first tap assembly towards the piercing member of the first tap assembly causes the piercing member of the first tap assembly to engage the first conductor, and displacement of the clamp member of the second tap assembly towards the piercing member of the second tap assembly causes the piercing member of the second tap assembly to engage the second conductor.
