Lightning surge protection that works

Most of us have “surge protector” power strips. They are supposed to protect against power line surges due to lightning and certain power line faults.

But do they?

Well, yes… To a small degree.

But if you want some serious protection, you need a whole-house surge protector.

From a brief intro to lightning, to how surge protectors work and how to install them safely, this episode has everything you really need to know…

Smart Meters are worse than you think

I recently learned the hard way what’s happening with smart meters in Europe. The same type of smart meter they’re using here in France has already been deployed in many EU countries.

Mostly, we hear only about the negative health effects of wireless smart meters, but the ones here only send data back over the power lines.

Nevertheless, it turns out smart meters here are still being used to pretty much screw many over.

In short, smart meters may mean less juice to power stuff, and more frequent main breaker trips as people exceed their (now reduced) capacity.

Waterproof cable and wire splicing made easy

If you’ve ever accidentally chopped through a wire or electrical cable, you know how much fun it can be to try to repair it so that it stays waterproof, dust proof, weatherproof, etc.

I recently had just such a fun experience myself. It turns out that there are quite a few nice products out there to make the splicing process WAAAAY easier.

Keep in mind that the type of splice you use depends greatly on the application – and even the type of wire (solid vs stranded).

A wire splice for an automotive-type application must be pretty strong, because vibration is obviously an issue.

An underground electrical cable doesn’t have to withstand vibration, but it definitely needs to be waterproof!

DEAR GOD the circuit breaker keeps tripping – What to do?!

First, remain calm. Second, watch this video!

A tripping circuit breaker or GFCI/RCD/differential breaker can be really annoying. It normally doesn’t happen.

When it does, the end result can be that you run around the room with your undies on your head, screaming like a wildperson.

Obviously, if your vacuum cleaner is charred and black and there’s a funny smell in the room, you’ve just figured out why the breaker tripped. But usually, the problem is a bit more subtle than that…

It turns out that with a bit of work, you can often cleverly narrow down the problem to one gizmo and save yourself some money – without setting anything on fire!

Yay!

EEK! #4 – What the heck is Power Factor?

Power factor is one of those things that sounds really complicated, but it’s pretty simple when you boil it down. And every now and then, knowing a little something about power factor comes in handy.

In short, power factor is the ratio of the real power consumed by a gizmo to the apparent power needed to be generated and delivered by the power company.

The reason for this “extra power” from the power company is the inductance and capacitance in your gizmo that results in shifting the AC current sine wave away from being perfectly in sync with the voltage sine wave.

You don’t really need to understand how all that works; just watch the vid to see why it matters!

EEK! #3 – 3-phase power

Why does AC electrical power come in 3 phases? What the heck is a “phase”, anyway?

In this episode of the EEK! Series, you’ll learn about 3-phase power and its advantages.

In short: fewer wires, more power, and the Earth itself is a conductor.

In addition, 3-phase industrial motors are more efficient and don’t require a starting capacitor since the 3 phases are “rotating” already.

Be sure to watch EEK! #1 and EEK! #2 first!

EEK! #2 – DC vs The Magic of AC

In episode 2 of the EEK! series, we cover the basic difference between direct current (DC) and alternating current (AC). Why is your home powered by AC, and not DC?

Simply put, AC allows the use of transformers to step up the voltage, step down the current, and therefore bypass the little problem of too much current flowing over a thin wire.

DC cannot be easily converted in this way for efficient power transmission over long distances. There’s more to say about AC, so look for a 3-phase video soon.
