Hall Sensor Power Measuring Apparatus Having Improved Accuracy Using Temperature Sensor

摘要

The present invention provides a hall sensor power measurement apparatus for improving accuracy by using a temperature sensor, which comprises: at least one main measurement module connected to a bus bar to measure voltage, current, and power; at least one sub-measurement module; at least one hall sensor; and a state display unit displaying a value measured by the at least one hall sensor. The hall sensor power measurement apparatus further comprises a temperature sensor unit and a voltage sensor unit, and further comprises a filter unit preventing power factor values from varying, which are generated in the measurements of the main measurement module, the sub-measurement module, and the hall sensor. In the filter unit, a resistor and a bead are connected to a current signal (-) terminal, and a capacitor, a noise filter circuit, and a bead are connected to a current signal (+) terminal.
