Did your television suddenly shut down after a storm? Perhaps the internet? Well, whether you work from home or just want to relax and enjoy your evening off, such inconveniences are not pleasant at all. They are caused by overvoltages which happen when the voltage in a circuit is raised above its peak limit.
To make things worse, personal belongings and residential building insurance do not always cover overvoltage damage. Spoilt electronics, therefore, give you the arduous task of determining whether the insurance company will even pay for the damage. Luckily, there is a simple solution to this problem. Just buy overvoltage-protected extension leads or an overvoltage-protection adaptor and you’re good to go.
Multiple extension leads with overvoltage control can lower voltage peaks, preventing harm to connected equipment. Alternatively, you can use an overvoltage protection adaptor to keep your electrical devices safe. Here is all you need to know about overvoltage protection:
What are Overvoltages?
Overvoltages are any voltages that intermittently exceed the mains voltage’s threshold level. Unfortunately, this problem rarely stops at the 230V main switch, but it also spreads to aerials and telephone lines, affecting any connected devices. Unfortunately, any additional current and voltage peaks are too much for the tiny motherboards, printed circuit boards, and ethernet cables. As a result, all these electrical devices end up getting spoilt.
That said, the final impact of this power surge, also known as overvoltages, is the electrical devices. However, if a protective device is installed to even out the power surge, these devices can be saved. Mostly, overvoltages can be caused by swapping impulses from powerful motors, welding equipment, or other powerful electric appliances.
Besides this, very high voltage peaks can be induced by indirect lightning strikes are they are more deadly. This is because there is hardly any device that can stand such high power surges. That said, it is important to protect all electrical devices and appliances from overvoltages. In addition, all power lines and aerials should be fitted with inbuilt power guards to reduce the impact of lighting strikes.
Why is Overvoltage Protection Important?
Device protection products can protect against overvoltages and electromagnetic current peaks. Mostly, these protection devices are used between the power socket or source and the device. Gas discharge valves and voltage-dependent resistors are critical components that ensure that harmful overvoltages are earthed in milliseconds. That way, they do not get to the protected electronics or devices.
Manufacturers exclusively employ high-performance modules that can be combined to create a wide range of products. This is because a well-thought-out range of protection levels ensures that the proper product is available for any need.
Overvoltages in the power supply can result from lightning strikes, causing damage to interconnected electrical appliances. These include food and coffee processors, TVs, internet routers, and laptops. In recent years, the number of pricey electronic equipment in private houses has increased dramatically. Electric appliances are likewise becoming smaller and more efficient. However, they are also becoming more susceptible to overloads.
When expensive electric items like televisions, laptops, and food processors are destroyed by lightning strikes and overvoltages, the financial loss and inconvenience are significant. Overvoltage prevention can lower voltage peaks to a level that is safe for the device, preventing these overvoltages. This is especially helpful during winter when the risk of lightning and thunder is substantially higher than in summer.
