Why is it important to have an indicate light on a surge suppressor?
the circuitry inside the suppressor that handles a surge can burn out if a surge is too high or lasts too long; in which case the cord would continue to work without surge protection making the connection vulnerable.
What is meant by a surge limiter?
A surge limiter (or surge suppressor) can be installed into your electrical panel to help protect your home from dangerous electrical spikes. It is usually installed in conjunction with a lighting arrestor. You can also buy single use surge protectors for sensitive appliances, such as computers, tv's, and stereo systems.
What is a surge suppressor is designed to do?
When the power applied to a surge suppressor goes above the rated amount, a certain amount of that power diverted down a ground wire and dissipated. Surge suppressors wear out and should be replaced every two years. Answer: Any suppressor that degrades or 'wears out' in two or ten years is grossly undersized, is ineffective protection, and may even create a fire. Suppressors must be properly sized to not fail. For AC mains, a suppressor must connect short to earth (be adjacent) to what actually absorbs energy). Suppressors that make an effective (short) connection to earth are also rated at least 50,000 amps. To not fail even on direct lightning strikes. An effective suppressor connects transients (even tens of thousands of amps) to what harmlessly absorbs that energy: earth ground. A completely different suppressor adjacent to an appliance must somehow block or absorb that energy. These hundreds joule devices require frequent replacement when absorbing destructive surges that exceed tens of thousands of joules. Suppressors that need frequent replacement are undersized and are typically too far (many tens of feet) from earth. Completely different devices, called suppressors, last for decades and are located adjacent to earthing electrodes.
What would be a typical joules rating for a surge suppressor designed for home use?
Destructive surges can be hundreds of thousands of joules. A protector rated for hundreds of joules does not claim to protect from the other and typically destructive surge. In fact, a 250 joule surge will simply be converted by electronics into low voltage DC to safely power its semiconductors. A destructive surge may be 20,000 amps. So a minimal 'whole house' protector for all homes should be at least 50,000 amps. Any protector that fails on a surge did not provide effective protection. And was a potential house fire.
What unit or measurement is used to describe the amount of work a surge suppressor can do before it stops protecting the circuit?
Depends on a type of protector. Some protectors work by absorbing energy. These might be rated in joules (pronounced 'jewel'). Are typically hundreds or a few thousand joules. Another protector for all types of surges works differently. It is measured in amps. For example a typically destructive surge (lightning is one example) might be 20,000 amps. So a 'whole house' protector is minimally 50,000 amps. Protector must not stop working. If properly sized, it only degrades. Protector that is grossly undersized stops working in a manner that violated the manufacturer's specifications. And that is a potential fire. A typically destructive surge can be hundred of thousands of joules. What does that do to the first type protector that must somehow absorb that energy? Two type protectors. One rated in joules. The other in amps.
How much is a surge suppressor?
It really does vary as to how much a surge suppressor costs depending on where you buy it from. They usually range from $15 to $25. Here is one site you can buy them: www.tigerdirect.com/.../category_slc.asp?...Surge%20Suppressors

How many Joules of protection do you need in a surge suppressor?
A suppressor is rated in joules, and a suppressor is rated as to the amount of joules it can expend before it no longer can work to protect the circuit from the power surge.I think you can find the answer to this question in Dehn-usa.com's "Lightning Protection Guide" or their "ABC's of Lightning". I put the link under the related links below.
The first measure you should take to help prevent damage against electrical problems?
A surge suppressor. Better yet,an UPS (uninterpretable power supply) with a built in surge suppressor.
Is a surge protector used for electrical fouls?
a surge suppressor or protector protects your equipment from spikes on the electrical line.
Why is it important to have an indicate light on a surge suppressor?
the circuitry inside the suppressor that handles a surge can burn out if a surge is too high or lasts too long; in which case the cord would continue to work without surge protection making the connection vulnerable.
What is difference between surge absorber and surge suppressor?
There is likely no difference. Neither is accepted terminology for a surge suppressive device (SPD). If these products have been tested by safety organizations such as CSA (Canada) or UL (US) or tested to international surge standards (IEEE, IEC), then they should bare the correct terminology, otherwise, they are not tested to provide protection to equipment during a surge. Surge Absorber acts as a load that utilizes the high current until it exhausts. but the surge suppressor diverts the high current into ground without reaching the sensitive parts of the circuit. Surge absorber degrades faster than a surge suppressor.
What device diverts extra electrical voltage on the line to the ground?
Surge suppressor
What is the purpose of a surge suppressor?
A surge suppressor or protector is used to protect electronic devices in case of voltage spikes. A surge protector works by limiting the amount of voltage supplied to the plugged in electronic devices by blocking or shorting to ground any voltage above the safe threshold.
What device protects a system against lighting strikes but does not protect against sags and brownouts?
A surge protector, also called a surge suppressor.
What unit of measurement is used to describe the amount of work a surge suppressor can do before it stops protecting the circuit form an electrical surge?
joules
Is it necessary to use an surge suppressor while testing a zener diode?
A: There is no reason if the source is stable
