The reason for installing a surge protector is because power surges are inevitable when dealing with electrical systems. Many people may assume that the electrical current flows at a consistent rate, but the truth is that spikes in the power flow can occur and for a number of different reasons. Lightning strikes can cause random spikes of electrical current flow, and when it happens, the power surge can overpower the electrical circuitry. Electrical components can become overstressed, destroyed and damaged to the point of requiring repair and even replacement. What’s worse, these surges are not limited to standard plug-in equipment; they can enter cable lines as well.
A surge protector that contains cable connections is utilized to protect devices, and are positioned between the electronic device and the cable cord. It is a buffer to divert electric current away from the devices to a grounding area. Within the cable surge protectors lies a Metal Oxide Varistor (MOV), which will grab and trap any excessive flow of energy, and in this way, it will give the devices the protection they require. In time however, each power spike degrades the effectiveness of the MOV and it would make a cable modem surge protector useless.
On these devices a cable surge protection signal will alert the owner if the device is working correctly. Otherwise, without the indicator light, a failure of the MOV, would result in the strip shorting out and may cause a fire. With a good protector, the contained circuit breaker will shut down the device’s power whenever a power surge occurs. A good quality surge protector may be purchased for $20 – $30.
The decision to use cable surge protectors is a good one since it will protect expensive high quality electronic devices such as entertainment center components. Electronic devices which have coaxial connectors can be protected using coaxial cable surge protection. They will protect your electronic equipment from the extreme damage that can be caused by major power surges, and they will also lengthen the life of those units.
Do cable surge protectors work for cable modems? Yes, they certainly do. A computer system can be protected from power surges with the use of a cable modem surge protector. Within the computer system, voltage sensitive components will be easily damaged by power surges. Not only can electrical surges damage the important data on the computer, but they will also reduce the computer life as well. Given the money invested in the computer and the important information it contains, the risk of losing it all to an electronic surge is not a risk to be taken lightly. A good quality surge protector installed in the electrical system, will provide the necessary protection to prevent data and hardware damage.
High power surges can be transmitted through any lines in the house that carry signals. Surges of that intensity can be triggered by lightening. Even for computers that are connected with the use of Ethernet cables, you should invest in a good quality Ethernet surge protector to protect the entire system. A computer system connected to a phone line by means of a modem stands a great risk of being damaged by power surges, so a protector that contains phone jack input should be purchased to prevent damage from happening. If coaxial cables are attached to any expensive device, coaxial cable surge protection must be purchased to protect those devices.
