Abstract

A current measurement system includes a magnetic field shield (3) that is configured to capture, to the inside thereof, a magnetic field (H) that is generated by a current (I) that flows through a cable (9), a magnetic field sensor (4) that is installed inside the magnetic field shield (3), a predetermined sensor, and a current measurement apparatus (2). The predetermined sensor is a sensor for detecting the cable (9), the magnetic field sensor (4) detects the magnetic field (H) at an installation location, the current measurement apparatus (2) acquires a detection result of the predetermined sensor and a detection result of the magnetic field sensor (4), identifies a center position of the cable (9) based on the acquired detection result of the predetermined sensor, and calculates a current value of the current (I) that flows through the cable (9) based on the identified center position and the acquired detection result of the magnetic field sensor (4).
