Power Outage (Electricity Loss Part 2)

A power outage (also called a power cut, a power out, a power blackout, a power failure, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. ... Other critical systems, such as telecommunication, are also required to have emergency power. 2.1 10 Common Causes of Power Outages 1. The most common cause of power outages: severe weather By far, the most common cause of power outages is severe weather. But there’s often more than a single cause of a power outage; you can have multiple reasons for a blackout. For instance, lightning can bring down a tree that cuts through power lines. Heavy rains can lead to floods or mudslides. Extreme heat and extreme cold can also damage components of the electricity grid. A study found major outages caused by severe weather occur at these rates: 8% by wind, including hurricanes, tropical storms and tornadoes 3% by lightning that can zap a transformer or fry wires 5% from snow and ice, leading to winter power ou...

Blackout and Brownout (Electricity Loss Part 1) (6-17-2020)

Blackout or brownout?  This topic is all about blackout, brownout and their difference.  1. Blackout Blackout is the failure of electrical power supplies. Blackout or power cut is the loss of the electrical power network supply to an end user. It is said that this is a period when lights are off because of an electrical and power failure. Blackout is also known as power cut, power outage, power out, power blackout, power failure. Blackout's first known use was in 1913.  2. Brownout Brownout is an intentional or unintentional drop in voltage in an electrical power supply system. It is also said that this period when the amount of electricity in an area is reduced. Brownout is originated from blackout by combining the words brown + blackout. Brownout's first known use was in 1942.  Now since we know their definition, we will know what is their difference.  1. A brownout is a partial, temporary reduction in total system capacity, while a blackout is a complete inte...

Hallucination Stages

Hallucination refers to when a person sees, smells, hears, feels or tastes something that does not exist. Hallucination is a common feature of schizophrenia, bipolar disorder and dementia but can also occur as a result of extreme fatigue or bereavement. Fever is another cause of hallucination in children. People who abuse drugs or alcohol are also more likely to experience hallucinations, particularly if they try to withdraw too quickly from the substance they are addicted to. Stages of Hallucination The most common type of hallucination is the auditory hallucination seen in schizophrenia, where patients experience invasive thoughts and start to hear voices. Hallucination can occur at different levels, ranging from mild to severe. The stages of hallucination are described below. 1. Stage 1 Also referred to as the comforting stage,a person may begin to experience a sense of anxiety, loneliness or guilt that can cause them to focus obsessively on thoughts that will relieve those feelings...

What Are The Different Climates

There are approximately five main climate types on Earth: Tropical Dry Temperate Continental Polar Climate is the average weather conditions in a place over a long period of time—30 years or more. And as you probably already know, there are lots of different types of climates on Earth. For example, hot regions are normally closest to the equator. The climate is hotter there because the Sun’s light is most directly overhead at the equator. And the North and South Poles are cold because the Sun’s light and heat are least direct there. Using this information, in the late 1800s and early 1900s a German climate scientist named Wladimir Koppen divided the world's climates into categories. His categories were based on the temperature, the amount of precipitation, and the times of year when precipitation occurs. The categories were also influenced by a region’s latitude—the imaginary lines used to measure our Earth from north to south from the equator. Today, climate scientists split the E...
