Hello all,
   I believe that a type of fuse is used that essentially melts when 
there's a short (near the actual xfmr). A few years back, lightning 
hit a pole right outside my father's business, knocking out one of 
the legs of the 3 phase that fed his building. There are 3 small 
bushings on the pole that contain the fuses. They can usually be seen 
hanging out of the bottom of the bushing. If one blows, it falls out 
of the bushing, and can no longer be seen protruding from the bottom. 
This serves as a visual indicator (from the ground) that something's 
amiss. There are other 'active' breakers, but they're usually at the 
substation (or another distribution hub).

Does anyone know if it is possible to intergrate a GFI into the
primary of a pig ? I know some distribution Transformers seem to have
thier own, breakers or GFIs. Last year a Squirrel climbed up on our
distribution transformer and hit the HV bushing. The Squirrel died of
course but only had two small burns, one on it's feet and one on the
nose. They were very superficial. This knocked out our power and the
local power company had to come and reset the breaker / GFI. In the
past I have seen Squirres explode when they contacted the HV bushing.
Does anyone have any Idea of what the power companies are using as
lnterruptors ?
