You dont get this on mainland....snake causes fault in feeder line. Fault causes isolation of a chunk of load. Sudden loss of load causes trip of 2 steam units due to generator overspeed (63hz at 2 seconds)....poor operators have to now spend a few hours checking and starting units back up LOL

So that overspeed trip is 5%? 3960 or 1890 rpm? When our coal units tripped we had to manually clean out the atom smashers (coal pulverizers). That BIG diesel (korean job) was 3% OS trip (103 rpm) ws

63hz relay that trips the gen breaker then the rest of the shit trips. The turbine overspeed trip didn't kick in...and guy said it never has since he been there except when they test it.
