The sleet clings to power lines and Transformers. As the weight of this ice builds up, it breaks the line away from the power pole. It also knocks branches from trees which can also break the power lines.

It is also essential for industrial processes, communication networks, and healthcare facilities. Additionally, electrical energy plays a key role in supporting renewable energy sources like solar and wind power, which are vital for reducing carbon emissions and combating climate change. Overall, the importance of electrical energy lies in its versatility, efficiency, and sustainability in meeting our modern energy needs.
What causes power black-outs in rainy days in electrical engineering perspective?
Many things cause faults, which are the cause of blackouts. A fault occurs when the dielectric isolation of a high voltage power line to ground, or to other phases is compromised, allowing current to flow between phases or to ground. In rainy conditions, this most likely occurs due to either high winds blowing conductors into each other (phase to phase faults, this would be known as galloping), or lightning, which causes molecules in air to line up, which reduces the dielectric strength of air and usually results in phase to ground faults. On lower voltage linesit is likely trees may make contact with a line (due to wind), which could cause faults requiring fuses to operate. Fuses are one time use devices, thus these sort of outages often require more time.
Can you run wire through the side of an outlet box?
Yes. Generally speaking you should use only existing knock outs. But it is certainly acceptable to make your own access. Be careful to use the correct connector, if required, and that your connector and wire do not interfere with installing the device safely into the box.
What is the source of electricity in Philippines?
The Philippines' total consumption is dependent upon traditional hydrocarbon sources of energy. Oil consumption, at 53 percent, accounted for the majority of the Philippines' final energy consumption mix in 2005, followed by coal at 19 percent. Renewable energy sources comprised 15 percent of consumption, followed by natural gas and hydroelectric consumption at 7 percent and 6 percent, respectively. The updated Philippine Energy Plan of 2005, which is a major reform agenda of the Arroyo Administration, is designed to move towards energy independence by first attaining a level of 60 percent self-sufficiency by 2010. The plan indicates that between 2005 and 2014, the economy's final energy demand will grow at 4.7 percent per year. To help meet growth in demand, part of the strategy is to increase the country's oil and gas reserves by about 20 percent and to reduce coal imports by 20 percent. The development of biofuels, as mandated under the Biofuel Act of 2006, will also contribute to the energy mix needed to eventually meet the goal of self-sufficiency
How do I calculate what gauge wire I need to use over very long distance runs - like 500 ft on 3 conductor solid copper wire at 1.5 amps and 120V-formula-or way to calculate for various lengths-amps?
If this is an electrical installation that needs to comply with the National Electrical Code, I'd advise you to read the code book article 310. It's not exactly easy to summarize, there are many ins and outs. For NEC purposes you would likely size according to Table 310.16. If you're experimenting, or just want some math to figure out what you need, check out NEC Chapter 9, Table 8. It lists the specific resistance per length of wire for different wire sizes. You can use this to determine how much resistance your circuit will have to overcome. As far as formulas, everything is based on Ohm's law. It is: Voltage (in Volts)=Current (in Amps) x Resistance (in Ohms). also: Current = Voltage divided by Resistance Resistance = Voltage divided by Current For example, NEC rules aside: If you have a 1.5 amp load at 120 volts, 500 feet away from your voltage source, that gives you 1000 feet round trip. If you were to use #18 copper, it's 8.08 ohms per 1000 feet. Dividing 120 (volts) by 8.08 (ohms) gives you 14.85 (amps). This wire's resistance will allow 14.85 amps to flow @ 120v, and your circuit is only 1.5 amps @ 120v. Of course, this would most likely not be allowed in your application by the NEC, as the smallest wire permissible for general use is #14. #18 is commonly used for low current loads, such as a fluorescent lighting ballast, and in this application it is permissible. Here is a way you can calculate the answer: First, You must determine how much voltage drop your device can tolerate. The NEC suggests no more than 3% drop for branch circuits. I will use 3% in the example. 3% of 120V is 3.6V, so the wiring run must drop no more than 3.6V. Now calculate the maximum resistance of the wiring run using R=E/I (resistance = voltage divided by current). Your example uses 1.5A, so let's use that. R = 3.6V / 1.5A R = 2.4 ohms Remember, use the voltage dropped across the wiring divided by the current through the wiring to get resistance of the wiring. Now, consult a table of wire resistance per size, such as NEC Chapter 9. The resistance in the table will be for a standard length, such as 1000 feet, so you will need to factor for your length. Remember to add both wires because the current has to make the round trip! Example: My distance from breaker to load is 350 feet. Double this because there are two wires = 700 feet. The 700 feet of wire can have no more than 2.4 ohms of resistance, so 1000 feet of the same wire can have no more than 3.43 ohms: 2.4 * (1000 / 700) = 3.43 Check your table for a wire that has 3.43 ohms per 1000 feet or less of resistance. According to my table, #14 copper has a resistance of 3.07 ohms per thousand, and will do nicely. I did not use your example of a 500 foot run, because it worked out to 1000 feet of wire, too easy and nothing to learn! #14 is normally good for 15 amps, so in this case we are not using it because we need the current capacity, but because we need to minimize voltage drop over a huge distance. Now, just for fun, let's reverse engineer your example using #18 wire to see what performance we could expect: #18 = 8.08 ohms per 1000 feet. Wiring run = 1000 feet (500 * 2) Voltage drop (E=IR): E = 1.5A * 8.08ohms E = 12.12V Voltage delivered to the load = 120 - 12.12 = 107.88V

Check power source (wall outlet), check any fuses or cut-outs. Get an electrician.
Can snow cause a black outs how?
Yes, heavy snowfall can cause power outages by weighing down power lines and poles, causing them to break. Additionally, ice accumulation on power lines can cause them to snap or sag, leading to disruptions in the electrical supply. Snow and ice can also create hazardous driving conditions, increasing the likelihood of accidents that may damage power infrastructure and result in blackouts.
How does an inline UPS protect computer equipment against electrical power brownouts and blackouts?
Online ups protect their computer equipment against electrical power browns outs and blackouts by using multiple power generators that have a back up system.
What does brown-out protection mean?
I am no expert at all, but it is like the opposite of power-surge. So the electrical power is reduced which may mean that your electrical devices and appliances may be damaged if a brown-out occurs. It is also related to a 'black-out' when all power is lost (black-outs are safer for your electronics and appliances because mostly it is just like turning them off at the wall socket). You should have a power protection board that protects you from brown-outs (low voltage) and power-surge (high voltage).
What does it mean if you black out?
It is time to see a doctor. Black-outs can be caused by low blood oxygen and low blood sugar. There are many drugs that can cause black-outs as well as physical problems that can cause black-outs..

Hyperthyroidism can cause black outs and a lot of other medical symptoms. I tis important to balance the thyroid and see your medical professional for help in doing this.
