SURGE PROTECTION 101: ( Article intended for Home & Small Commercial & Industrial )
A Surge Protection Device (SPD) shields computers and other electronic devices from surges in electrical power, which flow from the power supply. Standard nominal voltage for home and office buildings is 230 V with + or - 10% tolerance from Utility. Long duration Over and Under Voltage can be solve by Automatic Voltage Stabilizer (AVS) but for short duration Swell / Surges / Transient Over voltages this must be protected by Surge Protection Device. Even though power surges are so brief that they are measured in milli, micro and nanoseconds, their magnitude can reach up to 6000V (6kV) which can cause considerable damage to electronic equipment.
"How it Works"
A surge protector works by channeling the extra voltage into the outlet's grounding wire, preventing it from flowing through the electronic devices while at the same time allowing the normal voltage to continue along its path. Electrical surges can damage computer equipment by burning its wires or gradually over time wearing down the device's internal components and even wipe out any saved data. Surge protectors can also protect telephone and cable lines as these also carry electric current.
"When to Use a Surge Protector"
Most people think that the main cause of an electrical surge is lightning, but that’s not true at all. Yes, lightning can and does cause electrical surges, but the voltage of lightning is so great that most surge protectors won’t be able to withstand their power. The main cause of electrical surges? Electrical devices that require lots of power to operate. Depending on the wiring of your home, you may notice at times that your lights flicker when powerful devices turn on and off, like your air conditioner. When these devices are switched on, they demand a lot of electricity, which puts a lot of strain on the grid and can cause surges.
When should you use a surge protector? All the time. The real question is really which devices you should connect to a surge protector. You don’t need a surge protector for your desk lamp or your standing fan, but you do want a surge protector for expensive devices that have intricate microprocessors, like computers, televisions, stereo systems, media centers, high-tech kitchen appliances, etc.
Commercial:
Surge Protective devices are used in commercial facilities to protect emergency lighting, computers, data systems and more.
Industrial:
Surge protective devices are used to protect machinery, telecommunications, control systems and more.
Residential:
Surge protection devices are used throughout today’s homes and apartments. There are two types used, plug in devices and hard wired protection.
