[Lowfer] Hz question.

: I've been doing some similar experiments recently with toroid ferrites for
: LowFER current sampling,

What have you found to be the best ferrite form for your sampler?  I want 
the AC line to pass through the ferrite without turns and maximum sampling 
capability.  I had thought about just running the sampling wire parallel to 
the AC line, but I think it will detect anomalies on the other lines, hence 
my idea of using a ferrite to help corral the currents to the sampling wire.
