The Importance of Electric Surge Protectors

Electrical surges can damage our electrical devices Protect them from being damaged with a surge protector.

Electrical surges are the number one culprits that damage our electrical equipment, especially computers. Electrical surges burn the wire of our computer equipment or even wear down the internal components of the computer or other devices. This can wipe out the data saved in our equipment. Because of this surge protectors have been manufactured.

What are electrical surges exactly? It is also known as power surges. It happens when a power is interrupted all too suddenly, such that a device currently plugged goes off and on in a matter of minutes. It can be caused by a lightning, or malfunctioning in the electrical company.

Surge protectors are designed to protect the electrical from any spikes in voltage. It serves to regulate the voltage of our electrical devices. They block or short the voltage to the ground which is at the safe threshold. These surge protector channels the excess voltage to the ground wire of the outlet so that these excess voltage would not flow directly to the electric device. Only the normal voltage continues to flow to the electric device. Even your telephone and cable lines can be protected by the surge protectors.

These surge protectors are placed in between the electronic devices and the main electrical outlet. This simply protects devices from electrical surges. Whatever power that comes from the main electrical outlet will always pass through these surge protectors. Most of the surge protectors found in the stores are displayed in a form of boxes of tissue.

We all know that electrical devices like refrigerators and air conditioners do need large amounts of energy for the switch and compressors to function well. Surge protectors also protect equipment that needs higher voltage surges.

Let us take a computer for example. We have different intensity of using the computer. If your computer is supplied with uneven power, it may have shorter life span. This can cause not only the loss of your data but also the damage of your hardware.

If you want to buy a surge protector, you should choose the one that fits the peripherals and appliance that you will plug on the surge protector. You should also check the energy rating. For computer, look for the one with an input jack for your internet connection.

Bear in mind that power surges can damage your surge protector's metal oxide varistors (or MOVs). You have to sacrifice your surge protector in exchange of your equipment. It is best that you buy the surge protectors that have light indicator for you to know if your surge protector is still functioning. These surge protectors may come in different variations. The very basic has only one plug outlet. The large surge protectors intended for multi plug cost a lot. But you can always be sure that your equipment is safe with surge protectors.

Surge protectors work like a sponge. They have a limited capacity to absorb the excess voltage. They work as absorber of excess voltage that may be dangerous to our equipment. They act as a guard of our electrical equipment because they prevent excess voltage from reaching the devices. Your surge protector must have a lower clamping but higher current rating. The one with higher current rating are more long lasting.

The surge protector's MOV is the one that diverts that extra voltage. This is the one that forms the connection of the two important components of electrical devices - the grounding line and the hot power line.

The MOV has three parts: metal oxide material, joined power and semiconductor grounding line. Remember that semi conductor's resistance depends on the voltage. When voltage is just above the correct level, the resistance is low. When it is too high, it is the time the MOV eliminates the current. If it is correct, the MOV does nothing.
