The possibility of a disgruntled employee has been floated but not confirmed. The following article shows that it could just be bad actors who know something about grids and are testing what they can get away with.

Just days after what officials are calling a “targeted” attack at two Duke Energy substations in North Carolina, NewsNation has obtained federal documents showing evidence of at least six other “intrusions” at Duke Energy substations in Florida.

In September, Duke Energy Florida experienced at least half a dozen “substation intrusion events,” according to an incident report obtained by NewsNation.

On Sept. 21, an intruder “forced entry” into the Zephyrhills North substation in Pasco County, manually tripping equipment that caused an outage lasting nine minutes, according to a report filed with the U.S. Department of Energy.

You have to be either ignorant or just plain crazy to attempt to manually trip a breaker at a high voltage Substation.  Typically, the voltages on the high side are anywhere from 25kV to 500kV, depending on whether they are serving the Transmission or Distribution system.  If that current arcs to your body while you are tripping the breaker, you could be talking 50 to 200 amps coursing through you, which would burn holes thru your body and stop your heart from beating.  Sort of like the electric chair times 20. We had incidences of line crews finding dead people fused to the inner coils of garden variety padmount transformers because they cut the cover bolts and were trying to steal the copper coils out of a live transformer, back when theft of copper was an epidemic in the early 2000's.
