Should I use surge protection for my household appliances?

The question of protecting your household appliances with surge protector is not a personal one, but its something you should take seriously, especially if you use sensitive or expensive equipment. The cost of basic surge protection or overvoltage is minimal compared to the price of equipment replacement such as audio or video equipment.

Surge protection should really be used for all electronic devices like computers, televisions, printers and DSL equipment. In fact, any equipment that is semiconductor based. The components of any of these devices are highly susceptible to sudden changes in voltage, especially voltage increases.

So how does surge protection work?

An overvoltage protection is usually placed in the power cord between the wall outlet and the device it is intended to protect. Some surge protection can also be used to protect telephone equipment by placing on the telephone line. They are designed to protect against what are known as voltage cuts or transients in an electrical circuit that can be caused by many different actions, some of which include:

Circuit Breakers tripping

Short circuit as a result of poor maintenance of wiring or corrosion.

Power failure

Fluctuations in force caused by the power-producing company

Lightening Strikes

Surge arresters generally protect against most of these events, but lightning strikes can give great tension in the tension of thousands of volumes. Even if there is a risk of lightning, the equipment should be completely insulated from power supply, including overvoltage protection. It is worth noting that the flash does not need to directly put power transmission lines to affect consumer supply. Other than flash, peak voltage voltages are usually in the order of several hundred volts and most commercially available protection devices will be designed to protect against power transitions in that arrangement.

An apparatus designed to protect against voltage chips will have a rated voltage voltage, sometimes known as voltage voltage. This is the voltage level at which the device will divert the unwanted voltage away from the line. The tension voltage should be a bit more than the desired voltage for the devices to be protected. Most surge arresters will have a voltage voltage somewhere in the range of 330 - 500 volts, with 330 volts being very common.

Another parameter to consider when buying voltage protection protective equipment is Joules rating protection, where a Joule is an energy device. The surge protection value will define the amount of energy that can be absorbed when voltage exceeds without the device failing. A properly designed protection device should only absorb a certain amount of energy before it fails, because by absorbing energy, this energy will be released elsewhere in the system. An overvoltage protection device must be designed to fail at reasonable value so that energy is released to the ground and away from the sensitive equipment. The higher the grade, the better the protection and typical ratings for surge suppression devices designed for the home should have grades in the range 200-600 Joules.

The time it takes for the protection device to respond to the increase in voltage is known as the response time. If the response time is too long, the damage can already be done, then look for devices with response times of approximately 1 nanosecond, which should ensure adequate protection.

Finally, good surge protection will have an indicator light to give you a visual representation that the device provides full protection. Most devices will burn out after a number of voltage tips, especially if these nails are of high size because the Metal Oxide Varistor (MOV) component has a limited life. Most multifunction headlights still work as a basic power cable without overvoltage protection after MOV has failed, but without the indicator light you had no opportunity to know.

If you currently do not have surge protection or are considering buying new computer or video equipment, it would be wise to invest in a relatively cheap surplus protection to protect your investment.
