Lots of variables to determine as each case is different. You need to know the voltage in the area, some areas are 13.4, some 34.5, etc. and you also
need to know what the area load requirements are.
There are numerous potential reasons for what these individuals believe they saw at this time. if a three phase fault or internal fault occurred on a
transformer or breaker it can and will cause conductor gallop, regardless of wind which would result in this type of display.
Typically distribution service has automatic reclosing which allows a breaker to reclose after a fault in order to restore service automatically, in
many cases they reclose three times before they lock out.
If such an event occurred, and the local provider had the reclosers on, and the source of the fault was not removed, it would have continued to occur
up to four times before the system would lock out.
In my opinion, this is a misunderstanding of the events due to poor communications by the local service provider.
