Electrical Saving Device

Now I would like to share knowledge of mine with all this blog visitors. Electrical saving device or some products may say as inverters is actually the same thing in my view.

Electrical saving devices acts as a power stabilizer in your home, when there are sudden surges, hills and valley in your electrical transmission, electrical saving device acts as a defense for your home electrical appliances. The present of this devices helps the electrical appliances life span increases as all the power that going through the power outlet to the electrical appliances is regulated at stabilize power output.

When there is a surges, the electrical saving device will act as a filter, it will filter the excess electrical pulses brought by the power lines. Hence constantly supplying the needed current only to the outlets. What happens to the excess current? Well capacitor in the device store the charges and use it when necessary.

How about valley? Capacitor that stores excess electrical charges caused by the surges than used to compensate the current decrement in the transmission. I don't know if we realized that our fan or lamps, sometimes flickering for a sec but not a while. That is because where there are too many power demands, the current has to be subsided equally among residential. But when there are no demands on the particular day, hills will appears. Your current will increase suddenly but no too high.

From this point of view, electrical saving device acts as power filter, stabilizer and whatsoever you want to call it. Although some salesperson out there do claimed that it could helps to save your electricity bills. Well it's up to you to monitor how the device works, it's either works for you or otherwise. The bottom line here, make the right decision for your home.

If you a electrical or electronic engineer, perhaps you could fix one ESD to your home and test for the amps [Ampere/Current] usage.

How to calculate

Power = voltage x current

For normal air conditioner, I've cited the info from other sites, if your house use 1.0HP it requires about 3.76amps of current.

So as believed or demonstrated at the shopping malls, your current running at 1.5amps to 0.7amps. So the are slight reduction there. But that reduction is at the mall. Is it works to your home? Now get your hands dirty, do some experiment [advised to professional only] with the current. But if you a common housewives, please don't try it as if you get electrical jolts. I will not be responsible for any loss.
