Non-contact electrical parameter measurement device with clamp jaw assembly

A clamp jaw assembly for measuring an electrical parameter in an insulated conductor, the clamp jaw assembly comprising:

• a first clamp jaw comprising a proximal end and a distal end opposite the proximal end;
• a second clamp jaw comprising a proximal end and a distal end opposite the proximal end, the first clamp jaw and the second clamp jaw being movable in relation to each other between a closed position and an open position wherein, in the closed position, the respective distal ends of the first and second clamp jaws meet to define a measurement area that is enclosed between the first and second clamp jaws, and in the open position the respective distal ends of the first and second clamp jaws are separate from each other to define a gap that allows a conductor under test to pass therethrough into or out of the measurement area;
• at least one sensor positioned within an interior of the first clamp jaw or the second clamp jaw;
• and
• a visual indicator disposed proximate the at least one sensor on a surface of the first clamp jaw or the second clamp jaw, the visual indicator operative to guide an operator to position the conductor under test proximate the visual indicator to provide electrical parameter measurements, wherein the visual indicator comprises a first color of a first portion of the surface of the first clamp jaw or the second clamp jaw that is different than a second color of a second portion of the first clamp jaw or the second clamp jaw that surrounds the visual indicator.

A device for measuring an electrical parameter in an insulated conductor, the device comprising:

• a body;
• a clamp jaw assembly coupled to the body, the clamp jaw assembly comprising:
• a first clamp jaw comprising a proximal end coupled to the body and a distal end opposite the proximal end;
• a second clamp jaw comprising a proximal end coupled to the body and a distal end opposite the proximal end, the first clamp jaw and the second clamp jaw being movable in relation to each other between a closed position and an open position wherein, in the closed position, the respective distal ends of the first and second clamp jaws meet to define a measurement area that is enclosed between the first and second clamp jaws, and in the open position the respective distal ends of the first and second clamp jaws are separate from each other to define a gap that allows a conductor under test to pass therethrough into or out of the measurement area;
• a first sensor positioned within an interior of the first clamp jaw proximate the distal end of the first clamp jaw;
• a second sensor positioned within an interior of the second clamp jaw proximate the distal end of the second clamp jaw;
• and
• a visual indicator disposed proximate each of the first and second sensors, the visual indicator operative to guide an operator of the device to position the conductor under test proximate the visual indicator to provide electrical parameter measurements, wherein the visual indicator comprises a first color of a first portion of a surface of the first clamp jaw or the second clamp jaw that is different than a second color of a second portion of the first clamp jaw or the second clamp jaw that surrounds the visual indicator;
• a display;
• and
• control circuitry communicatively coupled to the first and second sensors and the display, in operation, the control circuitry:
• receives sensor data indicative of signals detected by the first and second sensors;
• processes the sensor data to determine at least one electrical parameter of the insulated conductor;
• and
• causes the display to present the at least one electrical parameter to a user.
