Electrical Repairs: Protect Your Electronics

Electrical Repairs

How to Protect Your Electronics from Electrical Surge Events

1.0 INTRODUCTION

Avoid Electrical Repair. In this modern world, we have become very dependent upon our electronic gadgets. We use personal computers to work, communicate with friends, family members or business associates.

We often times store valuable files (such as financial documents, memos, reports, *.mp3 files, and now we also store important personal pictures) onto the Hard Drives of our Computers. Electronics are a very important part of our daily living and therefore so is electrical repairs. However, you can protect yourself and your wallet by taking the right steps. Don’t let electrical repairs rob your family of more important things.

We use the following electronic systems to entertain, educate, enlighten and comfort us. So consequently, at some point you will have to either replace these items or pay for electrical repairs.

DVD Players

HDTVs (e.g., LCD and Plasma)

Video Recording Equipment (for those of you upload your videos on to YouTube)

Gaming Systems (e.g., Nintendo, Wii, X-Box, etc.)

Central Air Conditioning System, Heat Pumps

Microwave Ovens

Refrigerators

These and other electronics gadgets require a significant investment to obtain in the first place; and are very expensive to do electrical repairs and/or replace.

And yet, amazingly, we do very little to protect our electronics from damage or attempt to make them last (and serve us) longer when it is so much cheaper than even doing electrical repairs. If you take the right steps.

This article is one of a series of three (3) articles on electrical repairs and other electrical subjects that discusses how to protect your electronics against the following destructive mechanisms that shorten its operating life.

Electrical Repairs

Heat

Electrical Surge/Spike Events, and

Electrical Noise

In this particular article, we are going to talk about “Electrical Surge/Spike Events”.

In particular, we are going to discuss the following topics associated with “Electrical Surge/Spike Events”.

What are Electrical Surge/Spike Events and How are they generated?

Electrical Repairs. How do you protect your electronics from Electrical Surge/Spike Events?

What are some guidelines that you should use when selecting a Surge Protector?

2.0 WHAT ARE ELECTRICAL SURGE/SPIKE EVENTS?

Electrical Surge/Spike events are typically defined as a “large current/voltage transients that occurs in an electrical signal or the power-line.” The right equipment can keep you from unnecessary electrical repairs.  .

Surge events typically last for a few microseconds and are then gone. Similarly, spike events will typically last for a few nanoseconds and are then gone. It makes no sense to have to replace electronics or make electrical repairs because you didn’t take the time to protect your home.

NOTES:

  1. 1 microsecond = 1 millionth of a second, and
  2. 1 nanosecond = 1 billionth of a second.

Both electrical surge and spike events can cause considerable damage to any electronic systems that are electrically connected to these power-line or signal-lines that are carrying this transient current and voltage. Electrical repairs can be quite expensive compared to the cost of protecting yourself.

For a typical person that lives in a home and own some consumer electronics, electrical surge/spike events can fall into one of two categories.

External Surge/Spike Events, and

Internal Surge/Spike Events

I will briefly define each of these types of Surge/Spike events below.

2.1 EXTERNAL ELECTRICAL SURGE/SPIKE EVENTS

External Surge/Spike events are called “External” because they occur “External” to (or outside of) your home.

 

External Surge/Spike events typically originate from one of two sources.

Lightning Strikes (during an Electrical/Thunderstorm), and

Switching events within the Electrical Grid. Not protecting your self can not only cause expensive electrical repairs but can also start a fire in your home.

External Surge/Spike events tend to be very large and damaging (especially if they originate from lightning strikes).

If these external surge/spike events were to enter your home (via the main power line and through the circuit breaker panel), they will destroy pretty much any piece of electronics that is connected to an electrical outlet in your home.

 

NOTE: These pieces of electronics do not need to be powered on to be destroyed.

 

They only need to be plugged into an outlet in your home at the time when this catastrophic electrical surge/spike event occurs causing damage that could need electrical repairs.

Fortunately, the External Electrical Surge/Spike events do not occur very often (e.g., a few times a year depending upon what part of the world you live in).

2.2 INTERNAL ELECTRICAL SURGE/SPIKE EVENTS

Internal Surge/Spike Events (as the name implies) are generated “internal” (or within your home).

 

Internal Surges/Spike events typically occur whenever the motor or an appliance (such as an Air Conditioner or the Refrigerator turns ON or OFF).

 

Internal Surge/Spike events tend to be much smaller than External Surge/Spike events but can still cause damage needing electrical repairs.

However, Internal Surge/Spike events occur much more often than do External Surge/Spike events (several times a day).

Over time, these smaller (though more frequent) internal surge/spike events will do damage to your electronics as well. Meaning you will need to replace your electronics or do electrical repairs.

Each time a motor of an appliance (such as an Air Conditioner or a Refrigerator) requires surge current (for it to turn on), or anytime the magnetic field (within the motor of an appliance collapses) whenever it is turned OFF, a damaging surge or spike is generated and can propagate throughout some of the power supply lines in your home. Doing electrical repairs to an air conditioner or electrical outlets can get expensive

Internal surge events will shorten the operating life of any electronic gadget that is plugged into an electrical outlet in your home.

NOTE: The electronics gadget does not need to be powered ON for it to sustain some damage from these internal surge/spike events.

3.0 HOW TO PROTECT YOUR ELECTRONICS FROM ELECTRICAL SURGE/SPIKE EVENTS

One of the most common ways of protecting many of your electronics from damage (due to electrical surge/spike events) is through the use of “power strips” that contain “surge protection” circuitry within them. These are much cheaper than doing electrical repairs.

Many power strips have surge protection built in, and in most cases, these types of power strips are clearly marked to reflect this.

Electrical Repairs. CAUTION:

There are some power strips that do not provide surge protection for your electronics. Be sure to get the strips that do provide surge protection.

Often times, people will still (incorrectly) refer to these products as “surge protectors”.

If you are looking to purchase a Power strip that contains “Surge Protection” circuitry, make sure that the labeling (on the box that you have in your hands) clearly indicates “Surge protection” or something like that.

If you cannot quickly find those words on the box, then I recommend that you put that Power-Strip box back on the shelf and go find a Power-Strip that has “Surge Protection” clearly marked on it.

3.1 HOW DO SURGE PROTECTORS WORK?

Surge Protector circuitry typically works by having devices (like an MOV – Metal Oxide Varistor) that “sits” between the “power-line” path and electrical ground within the power strip.

Many Surge Protectors will have several of these MOV devices in order to make them more robust.

Under normal operation, these MOV devices will do nothing at all and do not affect the operation of your appliances or electronic systems.

For you electrical engineers out there, I will tell you that these MOV devices presents a very high impedance between the “power-line” and “electrical ground”.

If a surge event occurs such that the “power-line voltage” exceeds a certain “threshold” voltage level, then the MOV devices will start to conduct current (and will then present a very low impedance path) between the “power-line” and “electrical ground”.

At this point, all of this excessive energy (from the electrical surge event) will be “routed” through the MOV devices (to electrical ground) and will be diverted away from your valuable electronics.

Once the “power-line voltage” returns to a normal level, the MOV devices will then return to their “high-impedance” state and will cease to conduct current between the power-line and electrical ground.

3.2 SHOULD YOU USE SURGE PROTECTORS FOR EVERY ELECTRONIC SYSTEM/ELECTRICAL APPLIANCE IN THE HOME?

In general, you should use surge protectors on all sensitive electronics that you would like to keep and use for some period of time.

If you have Surge Protectors for each of your sensitive electronics, then they will do a very good job protecting your electronics, for the duration that they (the Surge Protectors) function.

3.3 WHAT ARE SOME THINGS THAT I SHOULD LOOK FOR WHEN SHOPPING AROUND FOR SURGE PROTECTORS IN MY HOME?

In general, you should look for the following parameters/metrics whenever you are shopping around for Surge Protectors.

Clamping/Let-Through Voltage

Joules Rating

Response Time (if available)

 

I will explain each of these items below.

3.3.1 Clamping Voltage:

The “Clamping Voltage” level is also (often times) referred to as the “Let-Through Voltage” level.

Basically, this is the voltage level that will cause the MOVs (inside the Surge Protect system/Power-Strip) to conduct electrical current between the “power-line” and Electrical Ground.

At this voltage level, the Surge Protector will start to shunt the destructive electrical energy (from an incoming surge event) to Electrical Ground and will divert it away from your valuable electronics.

As I mentioned before, the MOVs will continue to shunt electrical current (from the power line) to Ground for the duration that the “Power-Line Voltage exceeds this “Clamping” or “Let-Through” Voltage level.

In general, the lower the “Clamping” or “Let Through” Voltage level the better the protection for your electronics.

Typical values for “Clamping” or “Let Through” voltage level are 330V, 400V, or 500V.

For 120V AC applications, I recommend that you use a Surge Protector with a Clamping Voltage level of 330V.

3.3.2 The Joules Rating

The “Joules” Rating for a Surge Protector will typically define the cumulative amount of energy that it (the Surge Protector) can absorb (throughout its operating life-time) without failing.

In general, the higher the number, the longer the Surge Protector will last and continue to protect your electronics.

Good Surge Protectors are ones that have a “Joules Rating” of 1000J or better.

NOTE: The “Joule” Rating does not reflect the total amount of electrical energy that the Surge Protector will shunt (to Electrical Ground) before failing.

The “Joule” Rating reflects the amount of energy that the components (mostly the MOVs) within the Surge Protector can absorb without failing.

In most cases, whenever an MOV shunts excessive voltage and current to ground (during a Surge Event), it (the MOV) is only absorbing a fraction of this energy.

Most of this energy is “being dumped” to Electrical Ground.

If your Surge Protector is properly installed, then for every joule absorbed by the components (inside the Surge Protector) another 4 to 30 joules was harmlessly shunted from the Power-line to Electrical Ground.

However, each time your Surge Protector responds to a surge event, the MOV devices do absorb some energy, and the cumulative amount of energy that these devices have absorbed moves closer and closer to the “Joules Rating” number and “failure”.

3.3.3 Response Time

Surge Protectors do not respond immediately to Surge Events.

There is a slight delay (or response time) before they respond.

The longer this response time, the longer your electronics sits exposed to the incoming surge event. Fortunately, most surge events do not happen immediately either. Most surge events take several microseconds before they reach their peak voltage.

By that time, most Surge Protection schemes (especially those using MOVs) will “kick in” within nanoseconds after the voltage level has exceeded the “Let Through” Voltage.

3.4 DO SURGE PROTECTORS LAST FOREVER?

Just like the smell of a brand new car, Surge Protectors do not last forever.

As these MOVs respond to Surge Events and “shunt electrical energy to ground” over time, they absorb some of that energy.

This process causes “degradation” and “wear and tear” on the MOV devices (and in-turn) on the Surge Protectors as a whole.

Eventually these MOVs will fail in one of two ways.

  1. The MOVs will fail to the point that they will no longer shunt excessive electrical energy to ground. In this case, the MOVs (are said to fail in an “Open” state).

Whenever this occurs, all of your precious electronics that is “downstream” from your Surge Protector are now “officially” un-protected and are now vulnerable to the next surge event that comes around.

  1. At least one MOV device will fail into a “Short Circuited” Mode. In this case, the MOVs may (though rarely) fail in the “Short Circuit” state.

Whenever this happens, the “failed” MOV device would continue to conduct high currents (from the Power-line to Electrical Ground) even when the power-line voltage is less than the “Let Through” voltage.

This type of failure mode could be very dangerous.

Fortunately, most Surge Protectors will typically have a fuse that will “blow” and will turn OFF the Surge Protector entirely, rather than risk catching on fire.

The main message here is this. Internal Surge Events occur many times throughout the day.

As these events occur, and as your Surge Protectors continue to function and shunt the excessive electrical energy to ground, these Surge Protectors eventually wear out and will need to be replaced.

SOME GUIDELINES ON WHEN TO REPLACE SURGE PROTECTORS:

You should replace your Surge Protectors under the following conditions.

  1. Whenever the Green “Protected” Light (on the Surge Protector itself) goes OUT.
  2. If you’ve owned your Surge Protector for more than 3 years.

NOTE: Having the Green Light ON is encouraging but is not a guarantee of adequate protection for the next surge events.

Replacing your Surge Protectors every three years is a good practice to keep your electronics protected.

Hire an Electrician for a Day: Tips That Promise More Bang for Your Bucks

Every home has a minor or major electrical work that goes unnoticed on a day to day basis. It may be due to busy schedule or sheer negligence on the part of the homeowner. But, before the situation goes out of the hands, it is better to hire an electrician who can solve all problems easily.

Homeowners prefer an electrician who can finish work in a day. Electrical work includes major renovation projects such as upgrading the electrical panel and repairing the aluminum wiring system. It includes minor repair work such as repairing a ceiling fan and changing lighting fixtures. Small renovation projects, maintenance touch-ups, and troubleshooting are also a part of the electrician’s job.

Homeowners shy away from contacting an electrician because they consider it to be an expensive affair. But the reality is different. To get more bang for your bucks, remember the following tips:

Amount of work

Before thinking about an electrician, you must make a list of the work which he will be doing for you. The list can include the following things:

 

  • Installing a new device or appliance in your home,

 

  • Wiring new switches,

 

  • Troubleshooting existing problems,

 

  • Repairing the faulty wires, etc.

 

Simply create a list of all the small electrical tasks which are pending since long. It will save your time and also get you more bang for your bucks.

 

Precautions before beginning the work

When you hire an electrician for an entire day, it is possible that your home will be devoid of power supply. For the same reason, keep your electrical devices fully charged and finish all your urgent work before the power supply is cut off. Also, make sure that your refrigerator is empty. If it contains food items, there is a chance that the items will go bad. So, plan well and execute your plan properly before the arrival of the electrician.

 

Time of work

Usually, an expert electrician can repair any electrical problem in a time span of 7 to 8 hours. But, a more wide-ranging work will take more time. For example, a list of small repair work can be finished easily in 7 to 8 hours. But if it is a major installation work of a number of appliances, then it will take more time to finish.

 

Overall, it is the sole duty of the electrician to come with his tools and equipment. Discuss each and every aspect of the work before agreeing to the quote. Moreover, you also have to take care that the electrician works according to the safety standards. Make sure that there is no additional problem due to the repair work. After the work is over, you have to check that the power supply is restored properly.

 

A safe and shock-proof home is a relief for all homeowners. And electricity is an important part for smooth functioning of every home. A slight glitch and the entire home can be at risk of unwanted consequences. To get more bang from your bucks, hire an electrician who will help you bid adieu to all your electrical worries.

Why You Need an Electrician

Electricians are required when you are building a new home and when you are need to do repairs, even those as minor as repairing a fuse. Hiring a fully qualified electrician is vital to ensure the job is done correctly and that it is also completed safely. Many house fires are started due to faulty electrical wiring, so problems with your electrical equipment and the wiring of your home needs to be attended to as soon as you notice a problem. Today most electrical work is illegal unless it is completed by a qualified electrician. There are many tasks involving electrical services around your home that require the hire of an electrician.

 

Construction

 

Many electricians are involved with the building industry and are hired to work on new homes. They will install all the necessary wiring that will bring power to your home. They will fit light switches and power outlets, connect the heating and cooling system to the power and install overhead lighting. They are also employed by construction companies and work on multi-storey buildings and any structure that requires electricity.

 

Maintenance

 

Another task of electricians is maintenance. These electricians will go out to homes and businesses and complete any repairs on electrical services. They will also install any new services that you may require, such as extra lighting or added power outlets. Electricians are often called out to older homes when renovations are being undertaken and also, as more electrical appliances are being used, adding the extra power outlets to cope with these technological advances.

 

Repairs

 

The repairs an electrician may undertake include fixing blown fuses, replacing any loose or dangerous wiring, fixing lighting and addressing any security system problems in both houses and businesses. Heating and cooling systems can break down, and electricians can be called out to repair white goods, such as washing machines, dryers, fridges, freezes and other appliances.

 

Inspections

 

Electricians will often conduct inspections of homes. People who are selling their home hire an electrician to do an inspection to update any problems and increase their chance of a sale. Buyers will send in an electrician for the same reason. When looking at buying a home you are facing the unknown in terms of any existing problems. For the safety of yourself and your family it is a good idea to have a professional electrician do a check before you consider buying the property. If you do purchase a home with electrical issues then you know what needs to be addressed before you move in.

 

Do It Yourself

 

You may be a bit of a handy man and do everything yourself, but when it comes to electricity you can not take the risk. With anything involving live wires you would be putting yourself at risk of serious injury or even death, so hire a professional and have the job done properly. Electricians have the knowledge and the proper tools, so it is not worth trying to cut costs by doing it yourself.
