Most of us have purchased a TV from a major retailer and almost always purchase a point of use surge strip with it. Despite this being a common add-on for this purchase, many people don’t know why they would need it and why it is important for a television.
The fact is televisions are sensitive electronic devices that do not react well to electrical surges. Most home appliances today such as dishwashers, washing machines, microwaves, and refrigerators are packed with electronic circuits. The majority of voltage surges in the home originate from some of these same appliances.
Voltage surges are caused when an appliance with a motor is turned on. Just think about how many times a day the refrigerator alone cycles on and off. A second source of voltage surge comes from outside of your home, most commonly when the utility power goes off and on from storms, accidents and regular system maintenance.
Voltage surges can be highly dangerous, and surge protectors will help prevent damage or injury. If a surge protector is not properly installed, anything higher than 120 volts may cause issues such as decreased device lifetime, burned wires, permanent damage or personal injury. A surge protector is made of an iron core transformer and a zener diode, and when a voltage surge occurs the surge protector provides additional internal protection.
The point of use surge strip for the TV is only one layer of protection which is commonly called stage 2. An additional layer of protection is called Stage 1, most often a piece of equipment attached to your service panel. This device provides protection from the small surges originating inside the home as well as those generated externally from the power grid. These two devices working in tandem will extend the life of the electronic components in all of your homes appliances.
It is important to check your surge protectors regularly to keep your devices safe. Generally, a green light indicator shows the device is functioning. One small add-on to the purchase of a new television can be trusted protection against any dangerous high-voltage scenarios. To ensure the protection of your electronics and your home, a surge protection system which includes stage 1 and stage 2 units is a good and safe plan.
