Jones took pictures and posted them on the f150gen14.com forum, saying, "2021 F-150 PowerBoost's 7.2kw Onboard Generator Saves the Day (3 days!) During Texas Power Outage. //
Took the keys with me and locked my door. It started and stopped the engine occasionally. Cell service was out also so I didn’t get a chance to try the Ford Pass App. Much quieter than the neighbors generator and I didn’t have to refill it in the cold every 8 hours. No filling stations open so he was in the dark after his two 5 gallon cans ran out.
According to Stat Trade Times, the An-124 was chartered from Antonov Airlines for a special ferry mission by Rhenus Project Logistics USA. The logistics company needed the aircraft to carry a massive power generator with a unique shape, requiring more cabin space to accommodate it.
This was no problem for the An-124, which has a payload capacity of 150 tonnes, more than enough to carry the 54-tonne generator. However, fitting the 10.5m long, 3.89m wide, and 4.13m high item required experts to be on hand for loading and unloading. The flight flew from Accra to Mumbai and then back once the repairs were complete.
A protective relay attached to that generator was designed to prevent it from connecting to the rest of the power system without first syncing to that exact rhythm: 60 hertz. But Assante’s hacker in Idaho Falls had just reprogrammed that safeguard device, flipping its logic on its head.
At 11:33 am and 23 seconds, the protective relay observed that the generator was perfectly synced. But then its corrupted brain did the opposite of what it was meant to do: It opened a circuit breaker to disconnect the machine.
When the generator was detached from the larger circuit of Idaho National Laboratory’s electrical grid and relieved of the burden of sharing its energy with that vast system, it instantly began to accelerate, spinning faster, like a pack of horses that had been let loose from its carriage. As soon as the protective relay observed that the generator’s rotation had sped up to be fully out of sync with the rest of the grid, its maliciously flipped logic immediately reconnected it to the grid’s machinery.
The moment the diesel generator was again linked to the larger system, it was hit with the wrenching force of every other rotating generator on the grid. All of that equipment pulled the relatively small mass of the diesel generator’s own spinning components back to its original, slower speed to match its neighbors’ frequencies.
On the visitor center’s screens, the assembled audience watched the giant machine shake with sudden, terrible violence, emitting a sound like a deep crack of a whip. The entire process from the moment the malicious code had been triggered to that first shudder had spanned only a fraction of a second. //
The test director ended the experiment and disconnected the ruined generator from the grid one final time, leaving it deathly still. In the forensic analysis that followed, the lab’s researchers would find that the engine shaft had collided with the engine’s internal wall, leaving deep gouges in both and filling the inside of the machine with metal shavings. On the other side of the generator, its wiring and insulation had melted and burned. The machine was totaled.
In the wake of the demonstration, a silence fell over the visitor center. “It was a sober moment,” Assante remembers. The engineers had just proven without a doubt that hackers who attacked an electric utility could go beyond a temporary disruption of the victim’s operations: They could damage its most critical equipment beyond repair. “It was so vivid. You could imagine it happening to a machine in an actual plant, and it would be terrible,” Assante says. “The implication was that with just a few lines of code, you can create conditions that were physically going to be very damaging to the machines we rely on.”
But Assante also remembers feeling something weightier in the moments after the Aurora experiment. It was a sense that, like Robert Oppenheimer watching the first atomic bomb test at another US national lab six decades earlier, he was witnessing the birth of something historic and immensely powerful.
“I had a very real pit in my stomach,” Assante says. “It was like a glimpse of the future.”

Load banks carry ratings for voltage, power, frequency, and other parameters. Using load banks where parameters differ from rated values makes them useful in a wider range of circumstances, but requires users to understand how circuit characteristics impact their maximum capacity. This article provides guidance for de-rating load banks accordingly.
De-Rating Maximum Capacity for Actual Circuit Voltage
Load banks should never be operated above their maximum rated voltage, but can be used for testing at lower voltages. Doing so, however, will affect the maximum amount of load a unit can apply according to the following formula:
[(Applied Voltage)2/(Rated Voltage)2] x Rated Capacity
The maximum load that a 400-kilowatt 240-volt load bank could apply to a 208-volt circuit would thus be calculated as follows:
[(208 V)2/(240 V)2] x 400 kW = 300 kW

Automatic Transfer Switches (ATSs) are available with and without provisions for switching the neutral conductor. These options accommodate backup power systems where a generator’s neutral conductor is grounded either (1) to the grounding conductor that leads to the facility’s grounding electrode near its service entrance, or (2) a separate grounding electrode near the generator. This article summarizes when a separate grounding electrode is needed.

The growing importance of power reliability has led a significant number of facilities to install multiple generators to meet their requirements for emergency/backup power. For facility executives who manage more than one generator, it’s worthwhile to evaluate the option of using a power control system to parallel generators.

Want to run your oil longer than you used to? Lots of people do. We take many factors into consideration when determining your optimal oil change. Many people think choosing the right oil is important, but in reality, you can run any API-certified oil indefinitely, as long as it’s not contaminated. That’s the real key: not contaminated, with metal, solids, moisture, or fuel. So what can you do to keep your oil in pristine condition? Enter bypass filtration.
In-line oil filtration — the oil filter that comes installed from the factory — filters oil entering the engine down to roughly 30–40 microns (millionths of a meter). This is about the most the in-line system can achieve, because when the oil is cold or the filter is partially plugged, a finer filter would cause too great a pressure drop, forcing open the filter bypass valve and allowing unfiltered oil to circulate through the engine.
Bypass filtration works differently. When this type of auxiliary system is installed, some of the oil bypasses the in-line filter system, flowing though a bypass filter and then returning to the oil sump. Using this method, sump oil is constantly being cleaned any time the engine is running, and it can be filtered down to a very fine size. All you have to do to maintain the system is occasionally change the bypass filter.
Bypass filtration systems remove blow-by and oxidation products from the oil and can help reduce silicon accumulations.
Base number is still needed in diesel engine oils to neutralize acids that form. Also the metalorganic additives which contribute to alkalinity reserve in the form of base number also provides important detergency properties to the engine oil. These are most commonly represented by the calcium and magnesium containing additives. Even though the base number starts out lower in today’s engines oils base number retention is actually better in today’s API diesel engine oil classifications. There is still some level of sulfur present, which can create highly corrosive sulfuric acid. And due to exhaust gas recirculation NOX compounds react and form a weaker nitric acid back in the oil. But the general rule used in years past of 50% reduction no longer has any real relevancy and the base number can go to very low levels while in service and not be a great concern. The level of base alkalinity is adequate to combat the level of acid creation in today’s diesel engine oils, even when the base number gets to low levels during service.
