An electrical power saver device was a revolutionary invention introduced a few years ago. The device was designed to be a means of tackling and offsetting the ever-increasing electricity prices all over the United States in cities such as Greenville, SC. However, since its advent, the device has been the subject of much controversy, with many consumers deeming it to be ineffective in lowering the power bill while others call it a technological marvel.

In this article, we will talk about what an electrical power saver device is and whether or not it is smart to use an electric power saver with a line meter to reduce electricity bills in Greenville, SC.

What Is an Electrical Power Saver Device?

An electrical power saving device is a small electrical device that essentially works to improve the efficiency of your energy consumption from the grid. The device is simple to use and can simply be plugged into any electrical socket, generally close to the line meter, for maximum effectiveness. The device is small enough in size that you can fit it in your hand and lightweight enough that you can carry it around anywhere you go.

The core principle of the device is to cut down energy wastage from appliances and make energy consumption more efficient. This helps you transform the majority of the electricity drawn by your appliances into useful output, thereby minimizing the power loss. This means that using an electrical power saver device; your appliance will be able to do more work than without it for the same amount of supplied energy.

As a result, your electrical appliances will require an overall lower amount of energy to fulfill your day-to-day needs and, therefore, will help you reduce your monthly electric bill. The device employs a network of capacitors to achieve this and requires no special installation or supplementary equipment.

Furthermore, the electrical power saver device in Greenville is the same as in the rest of the country. This means that the device is universal and can be used anywhere throughout the United States, making it all the more practical, especially when you’re on the road and have limited access to electricity.

Where Can the Electrical Power Saver Device Be Used?

Thanks to its ease of installation and universality, the power-saving device can be used in almost all types of settings, be it commercial or residential. For instance, you can use the device in hotels, motels, restaurants, offices, shops and stores, and of course, in homes.

The device is gradually evolving to become a staple of most business workplaces seeing as how the energy costs account for a large portion of the monthly and annual operating expenses for businesses in Greenville, SC. The ability of the device to reduce the electrical bill makes it a great tool for businesses to lower their expenses and increase their profitability.

The device is especially useful for states that have high electricity costs, such as California, New York, Vermont, and Hawaii. States such as South Carolina lie somewhere in the middle where the electricity cost is neither the highest nor the lowest, and so the effectiveness of the device boils down to the energy consumption of the person.

Seeing as how the average energy used by a home in the United States is 893kWh, using the electricity power saver with a line meter to reduce electricity bills would be a practical approach for most homeowners.

Using an Electricity Power Saver with Line Meter to Reduce Electricity Bills – How Much Can You Save?

Electrical energy savers have been in the market for many years now, over a decade in fact, and over the years, the effectiveness of the devices has only improved. The amount of energy you can save using these devices depends largely on a few key factors, which are:

  • The model and brand of the electrical power saver device you use
  • Your energy consumption
  • Whether or not you have any existing energy-loss reduction controls in place
  • The amount of inductive electrical load consumed at your property
  • The number of resistive losses due to poor electrical wiring

Generally, high-end models of the saver will be able to help save you more energy. Furthermore, the more energy you consume, the greater the power loss and hence the more potential your property has for power-loss reduction and energy savings. Also, if you already have certain control measures for reducing power loss for your home or workplace, the energy saver device will have a less noticeable effect on your electricity consumption.

When reducing the power wastage of your property, electrical power saver devices mostly reduce the wastage caused by your inductive loads, such as fans, pumps, and refrigerators. This means that the greater the portion of the inductive load in your net energy consumption, the more energy you’ll be able to save.

Moreover, if an outdated or poorly designed electrical wiring network causes a lot of resistive losses, power-saving devices can help you there as well. Since these devices work by reducing the current in the wiring, they can help reduce the resistive losses, thereby saving you energy.

All in all, this means that a home or commercial property owner will observe greater energy savings using power-saving devices if they have a high inductive load, high resistive losses due to electrical wiring, and a high-end power-saving device.

Overall, many manufacturers have claimed that the devices can help save anywhere from 25% to 40% energy. However, these figures were for the older models, and as mentioned before, the devices have only improved since then. As a matter of fact, some newer models claim an energy savings of 80% to 90%.

How Does an Electrical Power Saver Device in Greenville Work?

Before you understand how these miraculous power saver devices work, you should know where these power losses come from in the first place. The electricity that is supplied to our homes and commercial buildings from the grid is not stable in nature and is plagued by random and frequent fluctuations. These unpredictable spikes and drops in electricity make it unusable for the most part.

This means that the appliances in our homes and offices cannot convert this haphazard electricity into useful output resulting in it going to waste. This unusable waste electricity is converted into thermal energy due to the internal resistance of the electrical wiring and appliance components. As such, the wiring and appliance begin to heat up.

Knowing this, the fluctuations do not only cause wastage of power, but they also damage our appliances and wiring network due to the thermal energy they inadvertently contribute to. The thermal energy can deteriorate the wiring and appliance material, shortening their lifespan and increasing the risk of short circuits and other electrical hazards.

An electrical power saver is a device that tries to remediate this power loss and heating problem by smoothing out the fluctuating electricity profile and providing a more stable and consistent current supply using surge prevention technology. The fluctuations in the voltage, and consequently in the current as well, are unpredictable and therefore uncontrollable.

To tackle this problem, the power savers use a network of capacitors to filter out the fluctuations and only allow smooth current to flow through by storing and releasing the fluctuating current at the right time.

When there is a sudden spike in the current, the capacitors start storing the excessive current to negate the fluctuation. As the current starts to drop suddenly, the capacitors begin releasing the stored current again, trying to balance the downward fluctuation of the current.

The result is a smoother current profile with minor fluctuations, much less significant than before and, therefore, much more useful than before. Also, the resultant current has a value that lies between the minimum and maximum values of the previously fluctuating current.

Some manufacturers also claim that the power saver removes any form of carbon from the system, allowing for a smoother flow. In view of all of this, we can conclude that the electrical power saver device in Greenville offers two major benefits. First of all, you can use an electrical power saver with a line meter to reduce electricity bills.

Secondly, a smoother current profile means that less heat is generated in the circuit and appliance, as well as no more current spikes that can potentially kill an appliance. This entails that power savers not only protect but also extend the life of your appliances and other electrical devices.

It is worth noting that it takes at least a week for the system to properly adjust to the circuit before it begins to work at its best. In addition, the greatest amount of voltage savings will be experienced in regions where the fluctuations in the grid-supplied electricity are the highest.

The Negatives of Electricity Power Savers in Greenville

Like any other electrical device, power savers have their own sets of flaws, some of which have been the cause of displeasure for many homeowners. The first shortcoming of these devices is more of a false advertisement problem rather than a system fault. Many manufacturers advertise their electrical power savers as “intelligent power saving” devices.

However, a thorough analysis of the internals of the device has revealed that the device is essentially a network of capacitors and does not contain any integrated smart chip or system as its name or advertisements imply.

Another drawback, and perhaps the biggest one, of these power savers, is that they are only effective against inductive loads and not resistive loads. Confused? Let us explain!

There are two types of loads in any household or commercial facility. These are inductive and resistive loads. For resistive loads, these are those appliances that directly transform the grid-supplied electricity into useful output, such as heaters and lights, and as such, the amount of energy supplied to these appliances is almost entirely converted into their respective outputs and therefore has a power factor of 1. This means that resistive loads have very high efficiencies and minimal power wastage.

On the other hand, inductive loads are appliances that use electricity to create a magnetic field and have a power factor of less than 1. This leads to a phase difference between the current and voltage which in turn results in the loss of power. The energy used by the appliance can be calculated using the following formula:

By smoothing out the current profile and reducing the fluctuations in the current, power savers essentially enhance the value of the power factor. A higher value of the power factor means that the phase difference between the current and voltage is reduced, resulting in less power loss.

Also, keeping the above equation in view, we can see that a higher power factor means less amount of energy has to be used from the grid per kWh of energy used by the appliance.

To put it simply, electrical power saver devices will only reduce the electrical energy requirement of your inductive loads and not of resistance loads. So, for properties that do not have a lot of inductive loads in their systems, as is for many residential properties, the power saver will only marginally reduce their electric bills.
