摘要

SYSTEMS AND METHODS FOR MEASURING ELECTRICAL POWER USAGE IN A STRUCTURE AND SYSTEMS AND METHODS OF CALIBRATING THE SAME A magnetic field sensing device (110) is disclosed. The magnetic field sensing device (110) comprises two or more magnetic field sensors (211) configured to detect a magnetic field in a current carrying conductor, and a phase detector electrically coupled to outputs of the two or more magnetic field sensors. The magnetic field sensing device further comprises a phase indicator electrically coupled to the phase detector, wherein: the phase indictor comprises a display that indicates when the two or more magnetic field sensors are in a predefined position in relation to the current carrying conductor. 10026815_1
