There are a confusing amount of options for protecting home electronics from power surges coming both from within the home and outside it. Within the home, surges can come from refrigerator or air conditioner compressors turning on; and outside the home, surges can come from electrical storms or power company lines. Looking for answers on the internet is only slightly helpful, since there appears to be a dearth of black and white information from reputable sources, while there is a wealth of arguing shades of gray on forums.

This post does not propose any definite answers to the trickiest questions about surge suppression because there is a strong element of safety at issue, both to electronic equipment and to a home and its inhabitants. When it comes to solving electrical problems, there is no substitute for calling in a trustworthy and knowledgeable professional electrician. Clerks at electronics stores may or may not possess those qualities. Their primary quality lies in selling electronics, which doesn’t necessarily negate the other qualities, but the wise customer regards their advice skeptically so as not to end up like the customer played by Albert Brooks in the running store scene from his 1981 film Modern Romance, in which his brother, Bob Einstein*, plays a store clerk who ruthlessly upsells Brooks.
The first thing to know is that a power strip is not a surge protector. The second thing to know is that if a surge protector has coaxial cable connections for television or internet service, it is not absolutely necessary to use them. This is a matter of some controversy, and a researcher can end up floundering in internet forums looking fruitlessly for a black and white answer. Mainly it is important to understand that the best protection for electronics from surges traveling over coaxial cables coming from outdoors is proper grounding of those cables, preferably with a metal gas discharge tube integrated into a grounding block. Grounding is a complex subject and as such should be addressed by a qualified electrician when there is any doubt about it.
There is the question of signal loss when using a plug-in surge protector’s coaxial cable connections, and despite all the argument about it, throwing around of terms like “insertion loss”, difficulty of determining said insertion loss from manufacturer’s specifications, or use of expensive diagnostic equipment, the simplest answer comes from taking advantage of the signal diagnostics included within the settings menus of all modern televisions. Check the signal strength and quality with the surge protector connected in the cable loop and then again without it connected. A decent plug-in surge protector should show negligible signal loss. Signal is signal, and therefore the same diagnostic results for a particular plug-in surge protector should apply to internet signal. Length of cable runs and quality of the cable and its connectors will usually be the more important factor affecting signal loss.
The last thing to consider when using the coaxial cable connections of a plug-in surge protector is whether it creates a ground loop. That’s a subject which can make anyone but an experienced electrician dizzy, and for those folks who are hopelessly confused and have thousands of dollars invested in home electronics, it would be best to consult an electrician. For everyone else, it is best to understand a ground loop is not inherently dangerous, as long as everything is indeed grounded. A ground loop caused by differences in electrical potential between pieces of equipment introduces a buzz or hum of interference, and the easiest and cheapest way to minimize the problem is to clamp ferrite beads, or chokes, on the ends of coaxial cables and power cords.

Again, the best safety feature of any home electronics setup is proper grounding of coaxial cables and power cords, giving a path of least resistance for power surges, whether they arise from inside or outside the home. Add a quality surge protector to prevent damaging current from traveling the live wire into sensitive electronics and it will save them most of the time as long as dangerously high current has a path out of harm’s way.

A strong nor’easter – or northeaster, if you prefer – is causing havoc along the east coast from North Carolina to Maine and into Canada to kick off the first weekend of March 2018. Nor’easters typically occur in the colder months, almost always in the eastern third of the country, though occasionally slightly farther west, as in November 1975 when a storm whipped up Lake Superior, sinking the SS Edmund Fitzgerald, and they can be as destructive as hurricanes when taking into account the wider swath and longer duration of a nor’easter over a hurricane. Blizzards with heavy snowfall, downpours and consequent flooding, beach erosion, and power outages and damage to houses, businesses, and infrastructure from gale force winds, all can be attributed to nor’easters.
The winds of a nor’easter never reach the highest speeds of hurricanes, but even 30 and 40 mile per hour winds in winter can cause trees and tree limbs to topple onto overhead power lines. The ground does not dry out as quickly in winter as in summer, and that can make the difference between a tree staying upright in high winds or falling over. Add the weight of snow and sometimes ice, and not only tree limbs and trees fall, but even utility poles may snap off at ground level. It’s not uncommon then to hear reports during a strong nor’easter, such as the one currently blowing along the upper east coast, of millions of utility customers being without power, sometimes for days.

After every particularly bad storm that causes massive power outages, many people want to know why in this country most of the power lines are still above ground, where they are vulnerable to storm damage. They want to know why more of the lines aren’t buried, seemingly out of harm’s way. The blizzard of 1888 brought New York City to a standstill, and the effect was that city leaders made a determination afterward to start placing essential services underground, in particular building a subway system to help city inhabitants keep moving no matter what the weather. Putting in new facilities at a time when the city was still in the process of being built out to its full potential turned out to be not as disruptive and expensive as it would be today, now that every square mile of Manhattan real estate has something already built on it.

Developers building new upper middle class subdivisions sometimes put the power lines underground because those developments can absorb the extra cost, typically 10 times more than overhead lines, and because the pleasing aesthetics and perceived security of underground lines enhance property values. There are drawbacks, often overlooked, such as the vulnerability of any overhead lines feeding into the new development, and the increased time and expense for power company crews to locate and fix compromised underground lines. One of the ways an underground power line can become compromised is through flooding, in which water or even water vapor will find its way into any vulnerability in the line’s sheathing and short out the line. Lines are usually buried from 24 to 48 inches deep, which in most cases is deep enough to insulate them from digging accidents and the soil water pressure of ordinary rainfall. In floods, however, the soil can become so waterlogged that pressure builds high enough to force its way in toward the power line.
There is no one absolute answer to lessening the risk of losing power during a storm, other than to disengage from the power grid entirely. For those who remain hooked in to the grid, some peace of mind can be had by purchasing a portable generator or installing a standby generator. Power companies should put more of this country’s grid underground in spots where the benefits can be greatest, leaving the rest of it above ground where the costs are prohibitive. Utility customers may wail once again about all the damaged above ground lines once this latest nor’easter has moved on out to the open ocean, but they often quiet down once they hear how much their power bill would have to be hiked and for how long in order to pay for putting the service below ground. The people who have it worst in some ways during a storm and for days or weeks afterward are the power company workers who have to be outside in dreadful conditions doing what is a dangerous job even in sunny, balmy weather, and is many times worse in soaking rain, blowing snow, pelting ice, and winds that could throw anyone off course.

Few things are more frustrating than dealing with poor or indifferent customer service. Calling a company’s customer service number – if you can track it down – usually involves navigating a phone tree of options that may or may not result in discussing your problem with a human being, and then only after waiting on hold. When you do get to talk to a person, that person may be based at a call center in India, and while they are almost always polite and professional people honestly trying to do a good job, there can be language and cultural barriers getting in the way of resolving your problem. Some companies have reacted to customers’ frustrations by touting that their customer service representatives are based in the United States, and to avoid long hold times they offer to call customers back.
Email is a somewhat better route for dealing with a company’s bureaucracy if you don’t mind delays of a day or two in getting a response. If you have follow up questions, the back and forth can stretch to a week or more and can feel like dancing with an elephant. Even though you might think there is an advantage to having your questions and their answers in writing, it has come to be more of a stumbling block than it used to be as reading comprehension deteriorates in the population. Consider how many times you have written an email to a company’s technical support only to find out after the usual one or two day delay in getting a response that they obviously misunderstood your question. They read the first sentence, and whatever followed made their eyes glaze over, because after years of exposure to television and the internet, they no longer have the attention span to comprehend anything longer than a snippet or a sound bite.

Of the three major technological ways of interacting with customer service, that leaves chat, and it turns out to be the most satisfactory in many ways for both customers and companies. Unlike a phone call, chat leaves a customer freer to do other things while waiting for a representative to come online or even while the chat is taking place. Unlike email, chat response times from companies are far quicker, and in many cases quicker than phone call response times. And like a phone call or face to face interaction, chat allows for immediate clarifications of misunderstandings. There is back and forth between the customer and the representative as in a phone call, and at the end the customer can print a transcript. Companies prefer chat, too, because it is cheaper to run than a call center on account of the flexibility the representatives have in handling multiple customers at once, and because the experience leaves customers more satisfied than dilatory email responses.

But what about older folks, who are often not as technologically savvy as the rest of the population, or what about people who simply don’t want to hassle with computers? These people prefer to contact customer service the old-fashioned way, either in person or by phone. They experience even more frustration than the rest of us because companies have mostly moved away from those older methods as being too costly, and even seem to actively discourage their use by making the experience unpleasant and time wasting. That can lead to serious consequences for the elderly especially, as their frustration with modern customer service options leads them to take foolish risks, like trying by themselves to dislodge a fallen branch from the power line service drop to their house after a storm rather than calling the power company to have them remove it, a service power companies perform for free because the hazard is serious and people should not be discouraged by a fee from having the problem resolved safely.
The 120 volt insulated line connecting to a house or apartment building can be every bit as dangerous as the higher voltage lines going from one utility pole to the next, and you have only to make one mistake with it and you’ll never make another. For safety reasons like this, it is vital that companies who deal in dangerous products like electricity and home generators and space heaters not hide their old school customer service contact points as some modern companies have done. We can gripe as much as we like about the cable company’s lousy customer service, but their product can’t kill us if we mess with it (physically, that is; mentally – that’s open to question). A power line is another matter entirely, even when the birds seem to tell us it’s okay.

That may be, but for purposes of this post it is important to note that birds can perch safely on a power line because they come into contact with it at only one point, and therefore do not provide a path to ground. An exception can be found in the case of large birds such as raptors, whose extensive wing span can bring them into contact with two lines at once, or with a line and another point, electrocuting them.
