Abstract
A compensating apparatus for installing variation of a non-contact current sensor on a two-wire power cable includes a non-contact current sensor, a sensing element characteristic measuring unit and a non-contact current measurement module. The non-contact current sensor mounted top to the two-wire power cable further has a first current sensor, a second current sensor, and a third current sensor. The sensing element characteristic measuring unit is to construct a space characteristic measuring database for the non-contact current sensor respective to the two-wire power cable. The non-contact current measurement module is to pair the space characteristic measuring database so as to compute and further output a measured value of the current I in the two-wire power cable.
