lightning surge protection devices should i use surge protection for my home appliances

Whether to protect your home appliances with surge protection is a personal issue, but this is something you should take seriously, especially if you use sensitive or expensive equipment.Compared to the price of replacing equipment such as audio or video equipment, the cost of basic surge protection or surge suppression is the lowest.Surge suppression should really be used for all electronic devices such as computer monitors, TVs, printers, and DSL devices.
In fact, any equipment is halfBased on conductors.Some components in these devices are very vulnerable to sudden changes in voltage, especially the increase in voltage.How does surge protection work?Surge protectors are usually placed in the AC power cord between the wall socket and the device it intends to protect.
Some surge protection devices can also protect telephone devices by placing them on telephone lines.Short circuit caused by poor line maintenance or corrosion.Surge suppression devices often prevent most of these possible situations, but lightning strikes can create a surge in voltage up to thousands of volts.
Even if there is surge protection, if there is a possibility of lightning, then the equipment should be completely isolated from the power supply, including surge protection.It is worth noting that in order to affect the supply of consumers, lightning does not have to directly impact the transmission line.In addition to lightning, the surge in peak voltage is usually several hundred volts, and most commercial protection devices will be designed to prevent power transient in this order.
The device designed to prevent voltage spikes will have a rated clamping voltage, sometimes called let-Through voltage.This is the voltage level at which the device will transfer the unwanted voltage from the line.The clamping voltage should be slightly higher than the voltage required for the protected device.
Most surge suppression devices will be at 330-500 volts, 330 volts are common.Another parameter to consider when purchasing a voltage spike protection device is the protector Joules rating, which is the unit of energy.The rating of the surge protection device will define how much energy can be absorbed in the event of a voltage transient, in the event that the device does not fail.
A well-designed protection device only needs to absorb a certain amount of energy before it fails, because by absorbing energy, the energy will dissipate elsewhere in the system.Surge Protection devices should be designed so that they fail at a reasonable rating, so that energy can be dispersed to the ground and away from sensitive equipment.The higher the rating, the protection and typical rating of surge suppression devices designed for the home should have 200-600 Joules.
The time required for the protection device to respond to an increase in voltage is called the response time.If the response time is too long, then it may have caused damage, so look for the device with the response time around 1 ns, which should ensure adequate protection.Finally, a good surge protector will have an indicator light that gives you an intuitive view of the full protection provided by the device.
Most devices "burn out" after some voltage spikes, especially if the magnitude of these spikes is large because the life of the metal oxide rheostat (MOV) assembly is limited.Most of themAfter the MOV fails, there is no surge protection and the socket surge strip can still be used as a basic power strip, but you will not be able to know if there is no indicator light.If you don't have surge protection at the moment, or are considering buying a new computer or video device, it would be wise to invest in a relatively cheap surge suppression device to protect your investment.
