This could also be done by connecting a LED across a shunt resistor
on top of the toroid and getting the current to flow through resistor
and LED. The light from the LED can then be detected by remote sensor
and the output monitored at a safe distance. Trouble is it will
be half wave and difficult to calibrate.
For better measurements use FM to encode more acurate current measurements.
A single PLL chip, battery, and di-cast Al box should do it.
