Line surges may have caused panel damage?

A vendor skid control panel was recently damaged. According to construction, intermittent ‘line surges’ were occurring and may have caused the internal devices and components to be “fried” in their own words.
I am perplexed as to where and how these so called line surges may have occurred since there was very little load present on the panel at the time.
The vendor skid is supplied by a 480V 3 phase temp power, 60A fused disconnect switch. Any ideas?

Or they don't actually know what happened so blamed it on line surges. Sort of like people blame things they don't understand on bad grounding.
