• Protect against surges, damage caused by induced lightning, electrostatic dis­charges, noise, and ground loops.
• Surge protectors are available for various network types.
• Protectors are also available for various communication lines.
• We even carry surge protectors for special equipment, such as CATV, keyboards, and more!
OVERVIEW
Here’s why you need a surge protector:
In an ideal world, the flow of electrical current in your com­puter systems would be equal at all times. No outside power disturbances would disrupt the balance of power in your electronic devices.
In the real world, however, several forms of power disturb­ances can wreak havoc on your electrical devices. These power disturbances come in the forms of induced transients (which include lightning, electrostatic discharge [ESD], and noise), ground-loop currents, and surges.
Although only a lightning arrestor can protect against direct lightning hits, a surge protector can guard your equipment against damage caused by induced lightning. To understand the need for this protection, consider the enormous magnitude of energy that a lightning strike generates. As this large current flows through conductors, the expanding magnetic field causes induced current to flow in nearby conductors that could then carry damaging impulses to computers.
A surge protector can also guard against the second type of induced transient, electrostatic discharge (ESD). What we commonly think of as static is that zap we get when we grab something metallic after walking across a carpet during the winter. This static is actually called triboelectricity, from the Greek word tribo, which means rubbing. When two unlike materials rub together, the electrons from one and the electrons from the other produce a negative charge (or electrostatic discharge), causing a potential difference between the two surfaces. The excess electrons look for a discharge path, which they find in any good conductor. The excess energy can damage your equipment.
A third type of induced transient, noise, can also damage your equipment. Noise is a signal appearing in a circuit other than the desired signal. It can result from lightning or ESD, but more commonly results from other events happening in the
environment. Low-magnitude noise does not bother a PC, but high-magnitude noise or impulses can interfere with data processing or damage internal components. Noise as it appears on power lines comes in two varieties: normal-mode and common-mode noise. Turning large loads off or on, or shunting utility power-factor correcting capacitors across the line, creates normal-mode noise. Lightning, tripping and reclosing utility breakers, poor grounding techniques, ground faults, radio transmitters, time clocks, and machine tools can cause common-mode noise.
Another hazardous form of power disturbance is called a ground loop. A ground loop is formed when a potential difference exists between any two places that are, by definition, at ground potential. A ground loop may form in a circuit when the circuit contains two or more different ground connections. This circuit may also be formed between boards inside a PC or in a local area network. Whenever there is some impedance existing between two points, voltage can appear across these points and current can flow. Ground loops can also develop because of a circuit wire’s length.
The final type of power disturbance which the protectors guard against is, quite obviously, surges. A surge is a short­term voltage increase that exceeds established upper limits for less than 2.5 seconds. Each type of electrical interface contained in your data communications equipment has an acceptable operating voltage range. Voltages above the range of the particular device’s interface can damage the device in two ways. First, a massive voltage (called a spike) can immediately damage your equipment. Second, multiple smaller out-of-range voltages can gradually damage your equipment over time.
Our surge protectors provide an immediate path to ground, so power disturbances go straight to ground instead of to your equipment.
