full range current sensor using multiple current sensors

摘要

According to an aspect of the present invention, there is provided a power measurement apparatus for measuring power using a magnetic field generated from a power measurement object, the power measurement apparatus comprising: a plurality of fixed grooves having different distances from the booth bar; A magnetic current sensor inserted into at least one of the plurality of fixing grooves and installed therein; And a current value receiver for receiving a current measurement value from the magnetic current sensor. The present invention relates to a full range current sensor using a plurality of magnetic current sensors. According to the present invention, one or more magnetic current sensors are attached to the object to be measured with a distance from the electric power measuring object, so that a more accurate current value can be obtained through the current value measured by the magnetic current sensor located at a distance corresponding to the predetermined current intensity It is possible to provide a full range current sensor using a plurality of magnetic current sensors that can be derived.
