Blown up surge suppressor module

This is a picture of a surge module taken from an LEA series type surge suppressor:

Looks like it took a pretty significant power hit, enough to explode several MOVs.  This site is at the end of a long transmission line that stretches across an entire county.  Over the years, the station has made many complaints to the utility company about the quality of their power and the frequency of interruptions encountered at this transmitter site.  Occasionally, something will happen.  Often times it is the figurative shoulder shrug.

That is why we installed the surge suppressor.
