The protective components inside surge protectors work by either absorbing over-voltage spikes outright or shunting them to ground. This keeps the amount of over-voltage reaching your device(s) to a minimum.

- Common causes of surges include: 1  Lightning strikes. 2  Power outages and downed power lines. 3  Tripped circuit breakers. 4  On/off cycles of large appliances and tools. 5  Accidents and malfunctions at the power company or on the electrical grid.

Surge protector help Surge protector help. My flat panel lcd tv died a couple of weeks ago, so I replaced it with a Panasonic projector. (Panasonic PT-AR100U) I'm a little lost and concerned on how to connect this into the rest of my home theater. My entertainment system has conduit running through the wall to the attic for the speaker wire, so I can run the hdmi cable to the projector with no problem. The problem comes with how to power the projector.

- Electronic equipment is far more susceptible to power surges or lightning damage than compressors or well pump motors. The possible exception would be if the insured has purchased a good surge protector for electronic equipment. 2. Find out if the neighbors have had damage due to lightning or a power surge. If lightning or a power surge came in on the power line, then all people off of the same utility transformer should have been affected. 3. Burned insulation on electric wiring is not necessarily an indication of a power surge due to lightning.

Have You Checked Your Surge Protector Lately? In Nebraska surge protectors with 2,000 joules of protection or less usually last around a year to two years before they should be replaced. Keep in mind that even if your surge protector has shielded you from one surge, the protector is now damaged slightly.hen a surge hits your surge protector, the impact of the surge is measured in joules. If you have a 1,000 joule surge protector and you take an 800 joule surge, you only have 200 joules of protection left.

Surge protectors do indeed go bad. But the reason they go bad has more to do with their environment than with their age.

Supressing the Surge In in some cases, if your home is near a large factory and you share the same transformer or electrical system, even simply powering heavy machinery on or off could cause a surge. A power surge can reach your home, fry your circuit breakers and spread to your outlets. If a device or appliance is plugged in, it may not survive the sudden surge of electricity. So what can you do to make sure your electronics survive an electrical surge? Start with surge protectors, both large and small.

How Surge Protectors Work 1 There are three levels of protection in the UL rating -- 330 V, 400 V and 500 V. Generally, a clamping voltage more than 400 V is too high. 2  Energy absorption/dissipation-This rating, given in joules, tells you how much energy the surge protector can absorb before it fails.

- Here are four things to look for when buying surge protectors: 1  First, the clamping voltage. 2  This is the voltage at which the varistor will kick in. 3  Common clamping voltages are 500 volts, 400 volts, and 330 volts. 4  A surge protector with a clamping voltage of 400 volts or 330 volts will give you the best protection.

Surge protector It is often claimed that a lower joule rating is undersized protection, since the total energy in harmful spikes can be significantly larger than this. However, if properly installed, for every joule absorbed by a protector, another 4 to 30 joules may be dissipated harmlessly into ground.

- Would be a great follow-up! Whole house surge protectors are another way to go. They are more expensive, but can be rated at 70-80,000 amps and 3-4,000 joules, or more. I think they start around $100, and many are $200-300, plus you might need to hire an electrician to install.150 for an 8-plug surge protector is a bit steep, considering a $30 will protect your stuff around the house just the same. The $30 surge protectors do not protect against in rush current. They only work on voltage rise.

Best Wall Mounted Surge Protectors This BESTEK surge protector runs all of the power through a single heavy-duty breaker located on the bottom of the device. This protects your devices from two angles. First, if you simply have too many things plugged in, the breaker will automatically flip off to reduce the risk of fires or component failure.

- HDMI Surge Protector. protects HDMI devices against Cable Discharges, Electrostatic discharge and Lightning as the clock within the HDMI technology is very susceptible to surge damage. It has a passive design and no power supply is supplied so surges cannot blow the HDMI Surge Protector out.

How Surge Protectors Work 1 A higher number indicates greater protection. 2  Look for a protector that is at least rated at 200 to 400 joules. 3  For better protection, look for a rating of 600 joules or more. 4  Response time-Surge protectors don't kick in immediately; there is a very slight delay as they respond to the power surge.

- Compressor surge is a phenomenon experienced when boost pressure inside the intake tract builds up and has no convenient relief method. This is usually caused from the throttle plate closing quickly.Changing load conditions (off throttle) resulting in varying amounts of exhaust gas can also simulate such conditions.he unique sound is caused by the pressure charge encountering the spinning compressor wheel on its escape from the engine. Compressor surge goes by many other names such as compressor stall, turbo dose or dosing, pigeon, turbo flutter/chatter and sometimes mistakenly wastegate chatter.

Whole-House Surge Protectors Prevent Damage “Most people wouldn’t think of not using a surge strip on a TV they just paid $1,500 for,” Mossop says. “But there’s a lot of electronics in your home that don’t plug into a surge protector.” For example, stoves, heat pumps and clothes dryers can’t plug into power strips.

- For this reason, all important electronics and appliances should be connected to a surge protector. Most surge protectors resemble power strips, but they actually contain additional circuitry designed to absorb excess electrical energy and prevent it from reaching connected equipment. Some models feature telephone/modem, coaxial and Ethernet jacks, which provide surge protection on those lines as well.

How Often Should I Replace My Surge Protector and Why Every time a power surge comes through the number of joules it surges is actually subtracted from the number of joules that the surge protector is rated for. What this means is that all surge protectors should be replaced every 6 to 12 months depending on where you live.

What to do when a power outage or surge damages your PC A power outage left it unusable. Electricity doesn’t always behave itself. Sometimes a power surge can fry a piece of your computer, rendering it useless. A surge protector significantly reduces the risk, but it’s still a possibility. And yes, a power outage often ends with a power surge. Should an electrical disaster leave your PC useless, you’ll want to protect your data, and then figure out what’s damaged. It’s easier and cheaper to replace a power supply than a whole computer.

Surge Protectors 1 You may see this rating on some surge protectors, instead of the newer VPR rating. When comparing SVR to SVR, a lower number usually indicates better protection. The lowest possible SVR rating is 330 volts.  Joule rating is the total amount of energy a surge protector is capable of absorbing over time.

How Often Should I Replace My Surge Protector and Why How Often Should I Replace My Surge Protector and Why. Hopefully you have your electronics plugged in through a surge protector. Not just your desktop computer but your laptop computer and printer too. In fact anything that is electronic and plugs in is going to survive longer if it is connected to power through a surge protector.
