What caused the Guri failure? Corpoelec union leader Ali Briceño said it was brush fire under the 765 KV trunkline which caused a surge in the system and caused Guri to shut down. There are no skilled operators left there to restart it.
Most people I talked to say the problem had to occur inside Guri’s turbines themselves. And that’s a scary thought. If they are damaged, they will be very hard to replace or repair. No money or skilled people.
I heard the turbines were damaged when the outgoing power impulse fed back upon itself after the transmission lines failed.

I don’t want to put this in the classification as “idiocy”, but it’s close.
ANY ‘short’ on any of the HV transmission lines is REFLECTED BACK into the rotating machinery as a change in TORQUE and this will be seen as stress and strain on every winding in the ROTOR and STATOR.
They likely killed some steam turbogenerators as they are termed.
This will take some time, maybe years, to fix at their rate of pace (into the ground) ...
