Those are overcurrent detectors. They have a spring loaded "eye" that
changes color when there is a fault on a phase; so it can be seen from the
ground.

Subject: [TCML] Mystery Cylinders on Primary Lines
Hi all,
Although this is certainly not directly Tesla coil related,
this was the only place that I figured that someone would
probably know the answer ;^) Can someone please tell
me what these "mystery cylinders" are that are clamped
on the primary lines in the first photo of my Flickr page?

Please read the description for the full description.
To keep the moderators happy, you may want to send
your response to me directly and off-list. ;^)
David Rieben
