How to Reduce Electricity
Reducing Electricity Bill:
A 100 watt device with Low POWER FACTOR consumes more power then a device with high power factor. Many of us will think that if 2 devices with same rated power will consume the same power. But the power consumption depends up on the power factor.
POWER FACTOR:
Real Power is the power required for the device to do the job
Apparent Power is the power consumed by the device to do the job.
Example: If an electric motor need 500 wats to do the job. But actually It consumes 700 to perform
its job.
The remaining 200 watts will be wasted in the form of heat and is of no use.
So, to save electricity and to reduce electricity bill, we have to reduce the wastage of unwanted power consumption.
Now a days most of the manufacturers are using appropriate CAPACITORS used for the device, this is one of the way why energy star rated devices get such good mileage.
CONCLUSION:
- Power Savers merges the cosine spikes in electrical waveform resulting in less spike height, so they can save bills a bit. They are simply plugged into wall plug and they do that by help of a capacitor. There are some indicator lights in the device which does nothing but just shows power ok. It can save power around 10% actually.
- Only inductive loads produce cosine waves and it can be useful in cases of electric heaters, air conditioners, electrical motors, induction cookers, etc.
Power Saver Simple Circuit:
To design a Simple Power Saver You just need a capacitor of 5-10µF
of 220V or 440V according to your area grid voltage is 110V or 220V.
For this, I’d recommend buying the oil based capacitors that are used in
ceiling fans. They are just 2.5µF, so you need to parallel 2 to 4 capacitors. After that, just connect them into plug and see it works.
