Sound 10: Power Outage Effect

This strong low pressure system is expected to bring higher than normal tides, heavy rains, exacerbating flooding concerns and increasing the risk for mud and landslides as the soils are saturated. The saturated soils will also increase the risk for potentially widespread power outages as trees could give way to the high wind gusts over the next few nights.

Make sure to be prepared for power outages. Charge the electronic devices, and make sure you have candles and flashlights ready. Also, be cautious if you have large trees near your home. It's probably a good time to take down or secure the Christmas decorations before the winds arrive.

How loud something sounds to you is not the same as the actual intensity of that sound. Sound intensity is the amount of sound energy in a confined space. It is measured in decibels (dB). The decibel scale is logarithmic, which means that loudness is not directly proportional to sound intensity. Instead, the intensity of a sound grows very fast. This means that a sound at 20 dB is 10 times more intense than a sound at 10 dB. Also, the intensity of a sound at 100 dB is one billion times more powerful compared to a sound at 10 dB.

System files are the largest concern. A sudden cut will corrupt the file if the operating system is busy editing an important file when the power outage hits (such as during a system update). Then, when you try to reboot the computer, the operating system crashes over this corrupted file and fails to boot.

Furthermore, frequent power outages can reduce the hard drive's physical lifespan. This is because the read-and-write head, which hovers over the spinning platters during operation, snaps back into its original position upon power loss.

A power surge will overload and fry the electronics within your PC. While an outage doesn't do a great deal of damage to a power supply or motherboard, the subsequent surge will. This will result in a computer that won't turn on after a power outage occurs.

As such, if you want to stay safe from a power outage, it's also worth investing in power surge protection. There's nothing worse than skillfully negating a blackout, only for everything to fry due to the surge afterward!

While power outages won't tear through a computer as a power surge will, they can still do damage. As such, if you want to take care of your data's health, it's a good idea to invest in some anti-outage precautions.

However, those few minutes give you plenty of time to shut down your computer manually to prevent damage. In addition, UPSs can sound an alarm to alert you of an outage or even tell your PC to shut down immediately.

Of course, it doesn't feel good to buy a laptop just because your power situation isn't ideal. Fortunately, grabbing a work laptop doesn't have to break the bank. Be sure to check out the cheapest high-quality laptops for an affordable way to continue working through outages.

Power outages can damage system files and data, and the subsequent power spikes can destroy hardware. As such, if you live in a neighborhood with unstable power, you should take the time to protect against both and save some headaches.

Conclusions and relevance: Among older adults with hearing loss, a community health worker-delivered personal sound amplification device intervention, compared with a wait-list control, significantly improved self-perceived communication function at 3 months. Findings are limited by the absence of a sham control, and further research is needed to understand effectiveness compared with other types of care delivery models and amplification devices.

"If one sums residential and small C&I [commercial and industrial] losses, the total is $2.5 billion in outage costs. If one assumes only residential customer impact, $65 million," he said in a tweet on Tuesday. He arrived at his estimate using the "Interruption Cost Estimate Calculator" created by the Lawrence Berkeley National Laboratory and Nexant, which compiles data on the estimated costs of power interruption.

Power outages often hit local businesses the hardest since they don't always have the same large-scale infrastructure and power generators that bigger businesses might have. A day of lost business can also have a greater impact on their bottom line, since it's a larger portion of annual revenue. Since the power cuts are concentrated in "suburban/rural" areas, Wara did not include "large C&I customers."

"The safety of our customers and the communities we serve is our most important responsibility, which is why PG&E has decided to turn power off to customers during this widespread, severe wind event. We understand the effects this event will have on our customers and appreciate the public's patience as we do what is necessary to keep our communities safe and reduce the risk of wildfire," PG&E's senior vice president of electric operations Michael Lewis said in a statement ahead of the intended power outage.

Take an inventory of the items you need that rely on electricity. Plan for batteries and other alternative power sources to meet your needs when the power goes out, such as a portable charger or power bank. Have flashlights for every household member. Determine whether your home phone will work in a power outage and how long battery backup will last.

Talk to your medical provider about a power outage plan for medical devices powered by electricity and refrigerated medicines. Find out how long medication can be stored at higher temperatures and get specific guidance for any medications that are critical for life.

Planned power outages are sometimes necessary when we make improvements to the electric system throughout our service territory. Most of the time, we can do this with no impact to you. Occasionally, we need to turn off your power for your safety and the safety of our crews. We know being without power is inconvenient and we appreciate your patience during these planned outages. We'll turn the lights back on as soon as we can!

To help us inform you of upcoming planned power outages, project updates or schedule changes, please check to make sure your PSE online account information is up to date with your current email and phone number.

A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user.

Modern power systems are designed to be resistant to this sort of cascading failure, but it may be unavoidable (see below). Moreover, since there is no short-term economic benefit to preventing rare large-scale failures, researchers have expressed concern that there is a tendency to erode the resilience of the network over time, which is only corrected after a major failure occurs. In a 2003 publication, Carreras and co-authors claimed that reducing the likelihood of small outages only increases the likelihood of larger ones.[1] In that case, the short-term economic benefit of keeping the individual customer happy increases the likelihood of large-scale blackouts.

Restoring power after a wide-area outage can be difficult, as power stations need to be brought back online. Normally, this is done with the help of power from the rest of the grid. In the total absence of grid power, a so-called black start needs to be performed to bootstrap the power grid into operation. The means of doing so will depend greatly on local circumstances and operational policies, but typically transmission utilities will establish localized 'power islands' which are then progressively coupled together. To maintain supply frequencies within tolerable limits during this process, demand must be reconnected at the same pace that generation is restored, requiring close coordination between power stations, transmission and distribution organizations.

Cascading failure becomes much more common close to this critical point. The power-law relationship is seen in both historical data and model systems.[7] The practice of operating these systems much closer to their maximum capacity leads to magnified effects of random, unavoidable disturbances due to aging, weather, human interaction etc. While near the critical point, these failures have a greater effect on the surrounding components due to individual components carrying a larger load. This results in the larger load from the failing component having to be redistributed in larger quantities across the system, making it more likely for additional components not directly affected by the disturbance to fail, igniting costly and dangerous cascading failures.[7] These initial disturbances causing blackouts are all the more unexpected and unavoidable due to actions of the power suppliers to prevent obvious disturbances (cutting back trees, separating lines in windy areas, replacing aging components etc.). The complexity of most power grids often makes the initial cause of a blackout extremely hard to identify.

This power outage came at a time of economic struggles, which some blame for the ensuing riots and looting. Many neighborhoods were hit hard, especially Crown Heights and Bushwick. Crown Heights had 75 stores within a 5 block stretch looted, while arsonists forced Bushwick to deal with fires well into the next morning. By the end of the blackout, around 4500 looters were arrested and 550 police officers were injured.

The first power outage was caused in Idaho, where there just wasn?t enough electricity. This caused severe voltage instability and the grid failed. Many areas within the United States were affected including, Idaho, Montana, Utah, New Mexico, California and Arizona. Luckily for the 2 million people affected, power was restored with in 1-2 hours.

The second major power outage was caused by the intense summer heat. Many major lines overheated and flashed, grounding to trees and in some cases, starting small fires. Ultimately, in about an hour, Oregon was disconnected from California and Northern California from Southern California. In total, around 4 million people went without power from anywhere between a few minutes to several hours. 041b061a72
