Surge Protectors: 5 Fast Facts

Fact #1. Power strips are not the same as surge protectors. However, many power strips do have built-in surge protection capabilities. The main use of a power strip is to provide additional outlets for one location. On the other hand, the priority of a surge protector is to protect devices from an overload of electrical current.
Fact #2. They work by blocking or shorting to ground any unwanted voltage spikes that occur above a particular threshold. When there is a spike or surge in electricity, special semiconductors inside are activated. The extra current flows through these semiconductors into the grounding wire. The grounding wire then directs the overflow safely back into the ground.
Fact #3. Power surges occur when something boosts the charge at some point in the power lines. The most familiar source is probably lightning. When lightning strikes near a power line, the energy can boost electrical pressure by millions of volts. A more common cause is the operation of high-power devices such as elevators, air conditioners and refrigerators. These pieces of equipment require a lot of energy to switch on and off. This switching creates brief and intense demands in power.
Fact #4. Many modern electronics are more sensitive to electrical current spikes than older appliances. This is because new technology uses increasingly small and delicate components. Microprocessors like the ones in computers and smartphones are particularly sensitive to this kind of fluctuation.
Fact #5. When picking the right surge protector, you should be aware of the response times. When there is a spike, it won't operate instantaneously. There is a very short delay. The longer the delay, the higher the exposure of dangerous voltage to your electronics.
