Device and Method for the Nondestructive Testing of Electrical Conductors

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a device and method for nondestructive testing of electrical conductors, such as wires or cables, by measuring the magnetic field around the conductor while compensating for its natural magnetic field using a specially designed, symmetric surrounding conductor. This compensation enhances the visibility of magnetic field deviations caused by material defects within the conductor, allowing for more accurate detection of faults without damaging the conductor.

Use CasesContent extracted from patent full text and abstract with AI.

• Quality control in manufacturing of cables and wires to detect defects before installation.
• Routine inspection of power lines and electrical grids to identify faults or weak points.
• Testing of conductive components in fuel cells, motors, and transformers for internal defects.
• Safety inspections of railway or subway electrical wiring systems.
• Maintenance of industrial automation systems that rely on electrical conductors.

BenefitsContent extracted from patent full text and abstract with AI.

• Provides a much higher sensitivity and precision in detecting internal defects in electrical conductors compared to conventional methods.
• Allows entirely nondestructive testing, meaning the conductor is not damaged during inspection.
• Enhances safety and reliability by identifying potential failure points before they cause breakdowns or accidents.
• Can be applied to various shapes and sizes of conductors due to the adaptable geometry of the compensating element.
• Improves efficiency and reduces costs in maintenance by enabling early detection and targeted repairs.

Patent Abstract

The invention relates to a device and a method for the nondestructive testing of electrical conductors (1). The inventive method and device enable the magnetic field of the homogeneous conductor (1) to be fully or partially compensated (4) and thus the deviation of the magnetic field to be detected to be much more striking. The total amplitude is caused, to a larger extent, by the material defects (2) to be detected.
