Abstract: A cable clamp system comprises a base assembly defining a base notch defining a notch axis and a carriage assembly defining a drive axis. The drive axis is substantially orthogonal to the notch axis.

Abstract: A clamp assembly comprises a base housing, an anchor member, at least one bracing member, an engaging member, and a clamp bolt. The anchor member supports the at least one brace member. The clamp bolt engages a threaded bore in the anchor member. When the at least one brace member is in an extended position, at least one set of brace teeth engages at least one set of base teeth to brace the at least one brace member against the base housing. When the at least one brace member is braced against the base housing, axial rotation of the clamp bolt applies a clamp force on the engaging member to clamp the cable between the engaging member and the base housing.

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.

Abstract: An impedance dropping dc power supply having an impedance controlled converter whose impedance adaptively changes as a function of the power supply's load impedance, to maintain the ac voltage across the primary winding of its power transformer below a predetermined maximum level, and to minimize the waste heat generated by the power supply that would otherwise have to be dissipated.

Abstract: An AC current sensor comprising a generally C-shaped main coil with a fixed gap between its ends. A pair of compensating coils are positioned at fixed locations in the main coil's gap. The longitudinal axes of the compensating coils lie on an imaginary straight line which extends between the centers of the main coil's ends; and their electrical centers are each spaced the same distance from their respective ends of the main coil. A compensating coil gap is defined between the electrical centers of the compensating coils. The main coil defines a measuring recess in which the sensed AC current carrying conductor is located when a measurement is taken. When the ratio of the size of the main coil gap to the size of the compensating coil gap is equal to the square root of three, the AC current sensor's accuracy and outside signal rejection increase most rapidly with increased distance of the sensed AC current carrying conductor from the compensating coil gap, and the AC current sensor's size can be minimized.
