bullet resistant power transformers

A sniper attack on two California power stations near San Jose on 2014 raised fears that such attacks could be carried out by people or groups that could lead to complete blackouts and the surveillance cameras at the station showed a seemingly organized attack to stop the station from work
The attack began before 1 am on April 16, when someone sneaked into an underground cellar not far from the busy motorway at a distance from the station and the telephone cables.
"Within half an hour, the sniper opened fire on a nearby power station and continued for 19 minutes,
Seventeen giant transformers were hit and a minute before the arrival of the police car, the attackers disappeared. To avoid power outages, electric network officials recharged areas from other stations and asked the Silicon Valley power plants to produce more electricity. But the return of the affected station to the service took 27 days
The station was targeted with at least 100 rounds, and one rifle was used while it was unclear whether this was a single attacker or group, and the reason for doing so was unknown. The person or people who made the attack were not found
The attack on the station raised doubts about other worrisome situations across the United States and what the Americans realize is that they now have something called a smart grid system, where the electrical network is connected to other networks over the Internet and computers. That a major attack on part of the network could cause a devastating disruption that could put tens of millions of Americans in the dark "
In 2015, three highly trained hackers stormed a power station in north Seattle last year with an electronic hacking of the station site. No warning bells or bright lights drew attention to the error, even with a host of malware on the computer, even if the intention was subversive. It was possible to cut off power from 325,000 subscribers
Concerns about the consequences of these incidents have become a concern, "a few months after a systematic attack on three electric facilities in Ukraine, which led to the interruption of electricity supply to about 225 thousand homes
In a two-month study, seven national security reporters at Medil University of the Pacific Northwest Press traveled to the Northwest Pacific to determine whether subversive attacks were possible, possible or even inevitable, and whether the measures taken were sufficient to secure the US electricity grid.
Northwest Pacific is a logical point of contact to study efforts to protect the electricity grid not only from the Internet but from physical and natural threats as well. The need for long power lines linking dams to the Columbia River to key population centers such as Portland and Seattle creates many bottlenecks as scientists expect the region to see a 9.0-magnitude earthquake over the next 50 years, prompting local and federal authorities in Washington and Oregon for summer training In preparation for such a disaster.
The investigation found that government officials, industry experts, engineers and scientists are well aware of the challenges they face and are working to combat threats to the network. But the dire predictions of total collapse in the event of a simultaneous and organized attack are exaggerated.
However, weaknesses remain and are not limited to one region. The network covers the entire country and parts of Canada, the network is a network of more than( 7,000) power plants, hundreds of thousands of miles of high voltage transmission lines and more than 55,000 switching stations
Back to electronic penetration After eight hours of work, security personnel had complete domain control, including control over data supervision and data acquisition, or complete control of the SCADA system
At the beginning of the year, the United States received from the Siemens Laboratories the transformers equipped with explosives (lead), in particular the capacity of one transformer 970 mega polt Amp and 345 kV
