If you have experienced a power outage due to a blown transformer, you may be wondering why it happened. You’ll find a few possible causes in this article. These include Overheating, Animals, Tree branches, and Storms. Hopefully one of these causes is yours! Here are the steps you can take to determine the cause of the power outage and to make sure your transformer is safe.
Overheating
An overheated transformer can be an immediate sign of a blown transformer. It can also be an indication of a larger problem, like bad weather or lightning. In either case, the extra strain on the transformer can lead to component failure. Additionally, high wind conditions can blow debris and trees onto power lines, causing an overheated transformer. In addition to causing an overheated transformer, freezing rain and ice can disrupt air flow and impede cooling.
In most cases, overheating occurs because the current in the winding is too high. However, a shorted turn can also cause overheating. In general, power transformers are designed to dissipate their internal heat, but they cannot do this in an enclosed transformer. This is why it is important to check the voltage supplied to the primary and the voltage generated by the secondary on the transformer before replacing it.
A blown transformer can cause a power outage within minutes, but in some cases it can take days to repair. A power crew may have to travel to the affected area to repair the transformer. If this is the case, it is important to be patient as the electrical provider works to restore power to most homes. While you’re waiting for the power to return, keep yourself and your belongings safe. If possible, have a flashlight nearby. Also, know where to exit the building if the power goes out.
Tree branches
High winds in central Pennsylvania have knocked down trees and snapped branches, resulting in a power outage. The outage has also disrupted the morning commute for many residents. On Wednesday morning, a WGAL reporter saw a transformer blow on top of a utility pole in Lititz, Pennsylvania. By the time he arrived at the scene, the transformer had blown through the pole’s wood support, and the fire had already started. In addition to a downed tree, Route 382 has been closed because of downed wires. Paola Tristan Arruda has an update on the trouble spots.
Another common cause of power outages is the striking of lightning on a power line. These storms can overload local transformers and cause major power problems. When a tree limb strikes a power line, it can cause a short circuit and collapse onto nearby power lines. Power lines are vulnerable to lightning, and tree branches can fall over them. It’s best to avoid standing in these areas if at all possible.
The outage began at 3:33 p.m. Monday, May 28, after a tree branch fell on power lines near Pennsylvania Avenue and Vermont Avenue. A similar situation occurred at West Outer Drive on June 11. A tree branch fell on the power line and shorted three wires. It took 45 minutes to restore power to all but 11 customers. This incident has been reported at a number of different locations in the city.
Storms
A blown transformer has cut power to nearly seventy thousand people in the Tompkins County area. The outage was caused by a surge of electricity that travelled through the neighborhood’s power lines. Affected customers can expect power restoration within an hour, and power should be restored by nine p.m. for customers closest to the blown transformer. Power was also knocked out for eight2,000 customers across the state.
If your transformer has blown or blew off its socket, stay indoors until it is repaired. Keep flashlights, extra batteries, and non-perishable foods and water close by in case you lose power. Also, remember that power surges can damage electrical appliances, which could result in a fire. Be sure to turn off all electronics and appliances while waiting for the power to be restored. To avoid causing a power surge in your home, make sure that you have all necessary supplies before going to bed.
Lightning can cause a power outage. During thunderstorms, lightning can strike power lines. As a result, a power surge can overwhelm local transformers and cause major problems. Lightning also damages equipment by blowing fuses, and trees may fall onto power lines. Fortunately, most power outages are not life threatening, but they can be extremely expensive. Lightning can also knock out electrical equipment and a whole city’s worth of other homes.
Animals
A recent blown transformer in Kalamazoo, Michigan has killed a squirrel. The power company blamed the animal’s presence for the blackout, which affected more than 2,000 customers inside the city and another 921 outside. The local politician visited the blown transformer and took pictures of the incinerated squirrel. The company has not yet released the name of the deceased bird, but the local media has reported that it is a common sight in the area.
While many of these outages are caused by weather or storms, animals can cause an electrical issue in a variety of ways. Birds, for example, frequently perch on electrical poles and power lines. The birds can then contact the wires and cause a power outage. The amount of damage an animal can cause depends on its size, location, and type. However, when the outage is small, it can affect a limited number of commercial customers.
Some utilities attribute power outages to wildlife, and some studies have even concluded that up to two-thirds of them are caused by squirrels. Squirrels, raccoons, and snakes are notorious culprits, but the worst culprits are arguably squirrels. Squirrels use power lines as a highway, so they often jump from one to another. Despite this, they still contribute to about half of all power outages in their territory.
Train tracks
Network Rail said that the outage was caused by vandalism and that the problems were contained within the signalling system. The problem lasted eight hours and affected some trains running to and from the area. In addition, more than a thousand passengers were evacuated to trackside areas. After eight hours, normal working hours resumed, but the outage caused a total of 14,522 minute delays and more than five hundred cancellations.
There are many implications for a railway undertaking, including a potentially damaging effect on reputation. Communications teams and the media may not be able to attend work if the railways are closed. Fires can also occur and the fire alarm system may not work. Alternative heating sources may not be as safe as electricity. In addition, the train crew may have to use non-electric equipment for heat. Ultimately, the issue is one of safety and reputation.
As of Monday afternoon, no injuries have been reported, but the incident has caused chaos for some commuters. Some of the affected areas include the University of Hawaii at Manoa’s lower campus. The incident also caused a power outage and forced Sac RT to suspend its light rail service. In addition to preventing the fire from spreading, it is also causing delays for local commuters.
Explosions
While it’s rare for a transformer to burst into flames, this type of electrical outage can cause explosive events. While transformers don’t normally explode, they can be damaged by lightning, falling trees, and damaged wiring. Explosions can also happen due to overheating insulation fluid. Here’s how to stay safe around a transformer. Keeping a hundred foot distance is a great way to avoid a transformer explosion.
On Wednesday evening, an electrical transformer blew and exploded in the San Francisco Bay Area. Witnesses reported hearing two explosions. The explosions were so large, firefighters in the area responded to reports of downed power lines and an apparent structure fire. Despite the lack of immediate dangers, residents of the surrounding neighborhood were unable to turn on their lights, due to the explosion. Fortunately, there were no injuries.
An electrical transformer is a vital part of our electric grid, and a sudden surge can cause an explosion. While they’re designed to shut down when they detect an energy spike, they may not be able to stop the electrical outage in time. Normally, they have a chamber of mineral oil to keep the circuits cool. Too much electricity can fry or melt the circuits, causing the mineral oil to combust explosively.
Repairing a blown transformer
If you have a blown transformer, you might find yourself in a power outage for hours or even days. To prepare for an outage, you should stock up on non-perishable food and flashlights. Power surges can cause electrical appliances to break down and even start a fire, so be sure to unplug any appliances before going indoors. Likewise, avoid opening your refrigerator or freezer as power surges can cause spoilage of food.
If you are able to isolate the damage, you can perform repairs yourself. This process usually takes an hour or two, though more extensive damage may require a longer time. Most transformer repairs can be done quickly, within a few hours. Depending on the extent of the damage, you may need the assistance of a professional to complete the job. Once you’ve completed the process, make sure you follow the manufacturer’s safety guidelines and follow any instructions, particularly if you don’t know much about electricity.
If you cannot fix the problem yourself, contact the electric company and get the transformer repaired. Depending on the extent of damage and the type of replacement, it could take several days. During this time, you can try to find a way to stay in the area and save energy by using alternative energy sources. During the time it takes to repair the transformer, you should avoid getting in close proximity to it.
