Agricultural
Electrical Networks as a Livestock Facility Management
Parameter
Neutral/ground networks have the characteristic of
using the ground as the return path of current because
it’s safer and more reliable. A portion of the
return current flows on the grounding network of livestock
farms. On an electrical basis, livestock is in parallel
with the grounding network, thus whatever is flowing
back includes a portion of current going through the
animal.
There is nothing exceptional about the presence
of current in the body of an animal providing the
voltage doesn't exceed the animal's sensitivity threshold,
which varies between species. Nevertheless, excess
current produces stress in the animal, and over time
affects its immune system, thus increasing the incidence
of diseases and reducing its performance.
The present
trend of farm automation is considerably increasing
the electrical load in animal environments.
Consequently, the return current increases, therefore
leading to more stress in the animal.
The return
current for traditional equipment is of 60 Hz and
may even reach more than 100,000 Hz
due
to new technologies that facilitate farm automation.
Besides
return current linked to the electrical network,
there also exists leakage current provided
by faulty
electrical equipment.
Of all livestock, the
dairy cow is more likely to be affected by this current
due to its low
resistance and an environment which regularly
puts it in contact
with complex electrical systems.
Our expertise
enables measuring, analyzing and neutralizing these
types of current.
