"Highpotter, wouldn't the arrestors only blow if they exceeded their rating? How often does this really occur?"
Lightning strike. Phase to phase fault.
Nick, when the right situation happens, they are "designed" to explode. All you find is a hanging tail with some of the arrestor still attached.
Any idea why they didnt spec out elbows, load break or deadbreak? Does the padmount have a oil switch? How is the system fed?
