Every decent consumer pays his precious dollars for quality products or services. We always like to get the best values for our hard earned moneys. For home appliances and other electronic and electrical devices, we want to make sure it lives out its service life, at the least. There are many ways of protecting our home appliances from unexpected circumstances we have no control over such as voltage spikes or power surges.
Sudden power outages are very critical to the life of every electronic device. Such gadgets or equipment follow a certain protocol of powering on or shutting down for good reason. Pulling the plug abruptly could damage the internal operating systems. The same holds true with power interruptions.
It is in this line of thought the surge protectors were invented. It is a protective device that protects electrical appliances from the ill effects of voltage spikes by attempting to regulate the voltage supply. This device does it in either of two ways. First, it can block the excess voltage. And second, it shortens to ground excess voltage.
A power surge happens when electrical charges down power lines get an unusual boost for one reason or another. This sudden increase in potential energy translates to an increase in the current flowing through your electrical outlet.
There are many causes of power surges. The most common is lightning. When lightning strikes near a power line, it increases the current flow along that line a million volts, possibly more. Your regular surge protectors are useless in this case and if you have any electrical devices plugged in, they’re going to be toast in a split second.
It could also be due to high-power electrical gadgets or devices. Elevators, refrigerators, air conditioning units, flat irons and similar devices require a lot of electrical energy to switch on and off, or to operate smoothly. This sudden demand for huge power output upsets the flow of electrical current along with your power system.
Sometimes, power interruptions could be out of faulty electrical wiring or any disturbances in the power lines, from the generators to the complex system of transformers and outlets. In the myriad of power lines and connections, there are numerous possible points of failure and a variety of reasons.
Obviously, power surges are unpredictable, unavoidable and damaging. The need for surge protectors only became significant in recent years as the trend to go micro also meant the minute devices modern tech and gadgets are more sensitive to surges than the pre-internet age electrical devices. Computers, particularly, have very sensitive microprocessors that work only with stable power supplies at the right voltage levels; not all electrical devices need surge protectors.
Procuring a surge protector is both practical and cost-efficient in the long run. Practicality-wise, if a device is able to handle the usual fluctuations in power supply and current flow, you don’t need to hook it up to a surge protector. A good example is your light bulb. However, if the device is sensitive to fluctuations and performance is sorely affected by fluctuations, you need to hook it up to a surge protector. Example: your computer.
Cost-efficiency-wise, if it is easier on the pocket to replace a busted device for an unusual, infrequent surge it can’t handle, leave it be. Otherwise, get a protector. It’s easier to replace a busted light bulb, which doesn’t happen often, than to replace your computer’s hard drive. Light bulbs are cheaper than surge protectors; hard drives are a lot more expensive than surge protectors, not to mention the data stored in it.
Groundfault circuit interrupter is a brand-new breaker which can not only protect household circuits from damages but also can protect people from electricity. The GFCI can inspect the current in circuit of null line and firing line. When there is no problem, the currents in two lines are the same, while when firing line is grounded like someone get electricity shock, then the current in firing line will increase quickly while the null line won’t. In this case, the GFCI will cut off power at once to protect people from electricity shock. A surge protector can protect connected devices from surges or spikes caused by lightning or other reasons. it can cut off power of a power strip when there is instant overcurrent. The GFCI responses faster than a surge protector to cut off power.
