1. An apparatus comprising:
a ferrite core;
a first winding inductively coupled with the ferrite core, wherein the first winding is configured to connect to a power generation system using a power line;
a second winding configured to transmit or receive a signal on the power line using the ferrite core, wherein the second winding is inductively coupled with the ferrite core and is connected to a first circuit;
a third winding inductively coupled with the ferrite core;
a sensor comprising a fourth winding configured to measure a magnetic flux produced in the ferrite core by the first winding, and
a second circuit connected to the third winding and the sensor, wherein the second circuit and the third winding are configured to produce a cancelling magnetic flux that cancels at least in part the magnetic flux produced in the ferrite core by the first winding.
