INTERFERENCE COMPENSATING SINGLE POINT DETECTING CURRENT SENSOR FOR A MULTIPLEX BUSBAR
First Claim
1. An interference correction type single-point detection current sensor for multiple busbars, the single-point detection current sensor comprising:
- a plurality of magnetic sensor modules which are brought in insulation contact with or installed adjacent to a plurality of respective busbars, measure currents flowing into the busbars using magnetic sensors, and output the measured currents;
a signal collection module which collects the measured signals output by the plurality of magnetic sensor modules; and
a signal interference correction module which derives corrected current values from which interference has been removed by calculating amounts of interference between the plurality of busbars in the signals collected by the signal collection module.

Abstract
A single point detecting current sensor includes a plurality of magnetic sensor modules, wherein a magnetic sensor module is installed onto each busbars with an insulation displacement contact or is installed adjacent to each busbar, and outputs the current through a busbars measured by a magnetic sensor; a signal collection module collecting measured signals output by the plurality of magnetic sensor modules; and a signal interference compensation module deriving a corrected current value for which interference has been removed, by calculating the mutual interference between said busbars using the signals collected by said signal collection module.
