Clearly, harnessing electrical powers that are fundamentally similar to lightning is no easy task, and when you throw all the above factors into the mix, you start to see how power surges can be dangerous. Knowing that power surges can take several paths and do not The actual spike in electrical current is usually extremely quick, less than a thousandth of a second. The electricity going to your outlets is typically around 120 volts, although it fluctuates between 0 and 169 volts. Lightning storms or irregularities in the power grid can sometimes cause electric current to jump to levels higher than normally required for household appliances. Bad wiring will need to be replaced. There are four main types of power disturbances: Voltage dips (also called "sags" or "brownouts") Remember that the performance of naked surge strip components in an electrical system is unpredictable. A surge in the electrical system is a short, quick rise within voltage that can cause an increase in electrical current. They can originate when an electrical utility company performs power grid switches, or when a thunder and lightning storm rolls into town. Electrical surges occur when an incident increases the electrical charge running through a power line at some point. When it exceeds 169 volts, that’s when a power surge occurs. have to enter through the electrical panel indicates a good All about the joules. Another cause of a power surge is the use of high power electrical devices like refrigerators and air conditioners. One problem with surge protectors is that the MOVs can burn out with one good surge. dish cable, through the incoming telephone lines, or through Voltage from the surge can vary, from a hundred to thousands of volts. Most home appliances and devices use around this much power, though the actual voltage level fluctuates between 0-169 volts. However, lightning causes electrical surges only every once in a while. These types of motors need an extra push of power to get them started. voltage of 169 volts as seen in the graphic below... A spike Only surge protections actually help protect your gadgets against power surges. thousand volts. High powered electrical devices can cause power spikes when switched on or when a particular, high energy component like a motor kicks in. Power surges – you probably know they can trigger a circuit breaker and shut off electricals, but do you know what causes them, or how they can potentially damage equipment around the home? What Are Surges In general a surge is a transient wave of current, voltage or power in an electric circuit. A surge arrester is device that intercepts electrical surges and sends the spike to ground before it can hurt a connected device. Lightning strikes are the one condition that’s mostly out of your control. contractor or other expert to determine the best application Power small power surges shorten the life of appliances and electronics. surges occur until the integrity of the electronic components However, during a power surge, the voltage exceeds the peak This is usually a sub-cycle overvoltage lasting less than a half-cycle of the regular voltage waveform, and can either be additive or subtractive with positive or negative polarity. house and its contents should be assessed individually. Repeated, Power surges can originate inside a home A power surge that destroys appliances is a rare event, but it can happen, especially in instances of lightning strikes. They can also occur if there’s a malfunction in a nearby transformer or transmission line. As a result, power surges can be seen as one of the “silent killers” of electronic devices. Startup current is the amperage / power draw peak that occurs when an appliance is operating in its most strenuous condition or cycle. Power surges have the ability to knock out your delicate electronics, cause fires, and wreak havoc up and down the circuitry of your home or business. Tripped circuit breakers might protect your home, but if they are damaged in the process, they can become a risk down the track. Basically, it’s a significant and often sudden increase in voltage that is above and beyond what your circuit was designed to handle. There are several sources of power surges. We cannot, however, guarantee the performance of all items demonstrated components. Expert knowledge is perhaps the best protection against power surges in the home. These arresters are also known as surge protectors or lightning arresters, but there are some very small differences between these devices. within the appliance. A whole house surge protector must be properly grounded, since without proper ground even the best surge protector will be unable to perform its job. Take pictures of any local trees that look at risk to damaging power lines and notify your council immediately. Most appliances and electronics used surges can enter a home through several paths. A number of different things can cause this to happen. A power surge in your electrical system can also be referred to as transient voltage. of lightning, it can take the path of the cable TV or satellite There’s no point spending over $1000 on fancy devices just to have them implode after your first electrical surge. Power surges occur when something boosts the electrical charge at some point in the power lines. Many power strips are just glorified extension cords without any protection. When lightning strikes near a power line, the electrical energy can increase the electrical pressure as high as a million volts. Alternatively known as a line surge or power surge, a surge is a short, fast rise in voltage that inherently causes an increase in electrical current or vice versa. or described in all situations.
