Embodiment Construction

[0022] A current measuring device disposed around the electrical conductor can measure the magnetic field induced by the current flowing through the electrical conductor and estimate the amount of current in the electrical conductor based on the measured magnetic field. However, existing current measurement devices suffer from several disadvantages. In one example, an electrical conductor adjacent to the electrical conductor being measured may generate a magnetic field that interferes with the measurement of the magnetic field generated by the electrical conductor being measured.

[0023] In another example, the current measurement device is calibrated to be positioned around the electrical conductor such that the measurement is sufficiently accurate, but the current measurement device is not properly positioned relative to the electrical conductor to a sufficiently accurate degree. When the electrical conductor is not in a nominal position relative to the current measuring de...

Abstract

A testing device measures a characteristic of an electrical conductor. The testing device includes a substrate having at least one flexible portion, at least one sensor located on the substrate, and a holding mechanism. The at least one sensor is configured to generate a signal indicative of the characteristic of the electrical conductor. The holding mechanism is configured to hold the testing device to an outer portion of the electrical conductor such that the at least one sensor is held in a position with respect to the electrical conductor.

Description

technical field [0001] The present application relates to test devices for measuring characteristics of electrical conductors. Background technique [0002] Current measurement is usually done either by momentarily disconnecting the circuit to be measured ("cut-off current") and inserting a sensing element in series, or by sensing the current without disturbing the circuit. There are many methods and techniques for measuring off current. However, disturbing the circuit to measure current would require breaking the circuit, and in many applications, breaking the circuit is not feasible. [0003] Solutions have been developed to sense current without disturbing the circuit. These solutions typically involve measuring the magnetic field generated by the circuit and estimating the current in the circuit based on the measured magnetic field. Devices that estimate current flow by measuring a magnetic field are typically placed around electrical conductors to measure the magneti...
