Power plugs are used to supply the electricity from the mainboard to the necessary electronic device. But when it starts raining, we always need to plug out and switch the board off. So that no electricity passes through. But most of the time it is seen that before plugging out, there is an unwanted electrical surge due to lightning. This results in the damage of the electronic device because it can only tolerate a limited amount of voltage. But when an electrical surge occurs, there is the momentary transmission of a higher amount of electricity.
So, before being too late, you must buy a Plug with a Surge protector (ปลั๊กไฟ คอมพิวเตอร์, which is the term in Thai). It helps to protect the electronic devices by acting as a mediator between the electrical surge and the devices. There are varieties of surge protectors’ plugs depending upon its use. They can be used at home, in the office or other complexes, malls, etc. But what is common in them is that they let you plug multiple components.
For the homely surge protectors, they only have a singular function. When the current flows to any electronic device, these protectors keep the voltage from reaching a certain level. If the limit is exceeded, the fuse of the board may burn, or the power supply may burn. Sometimes, the short circuit also takes place. So, it is the surge protector that sucks up all the high voltage electricity to keep your electronic devices safe.
How Surge Protector Functions?
A surge is so-called when a sudden increase in voltage remains for three nanoseconds or more than that. But when it lasts for one or two nanoseconds, it is called a spike. So, when this happens, the wire heats up and starts burning. Sometimes, multiple components of the devices get damaged. So, a plug with a surge protector diverts this extra electricity to the grounding wire by metal oxide varistor (MOV). This MOV is the connector between the hot power line and the grounding line. After this extra surgical current gets diverted to the ground, the voltage in the main power line becomes normal again. Thus, the sudden increase in electricity does not harm electronic devices.
As per the latest modification in surge protectors, they come up with USB ports. The USB Power Plug Price (ปลั๊กไฟ USB ราคา, term in Thai) is higher than the normal ones. But still, it is beneficial for our multiple using purposes in computers and laptops.
