Non-contact current measurement system

A method of measuring current in an insulated wire without galvanically contacting a conductor in the insulated wire, the method comprising:

• clamping, via an adjustable clamp assembly, the insulated wire between first and second clamp surfaces such that the insulated wire is held adjacent to a magnetic field sensor;
• autonomously determining a position of the insulated wire clamped between the first and second clamp surfaces;
• sensing, via the magnetic field sensor, a magnetic field generated by the current flowing through the insulated wire;
• and
• determining at least one characteristic of the current flowing through the insulated wire based at least in part on the determined position of the insulated wire clamped between the first and second clamp surfaces and the sensed magnetic field generated by the current flowing through the insulated wire.

A current measurement system, comprising:

• a housing;
• a movable clamp coupled to the housing that is movable to clamp an insulated wire under test;
• a position feedback sensor that generates a position feedback sensor signal that is indicative of a position of the movable clamp;
• a current sensor, wherein the movable clamp is configured to hold the insulated wire under test adjacent to the current sensor, wherein the current sensor is operative to generate a current sensor signal that is indicative of at least one characteristic of a current flowing through the insulated wire;
• and
• control circuitry communicatively coupled to the position feedback sensor and the current sensor, wherein, in operation, the control circuitry:
• receives the position feedback sensor signal from the position feedback sensor;
• receives the current sensor signal from the current sensor;
• and
• determines at least one characteristic of the current flowing through the insulated wire based at least in part on the received position feedback signal and the current sensor signal.
