CHANGE AFTER USE (V, A, PF, W)

There is no difference in voltage before and after use of the GREENPLUG. Some already existing power savers save power by lowering the voltage; however, lowering the voltage will also lower the output of the devices and cause them to malfunction.

The GREENPLUG maintains the constant voltage, so it does not affect the output. It is a smart device designed to save power without lowering the output.

The power factor means the ratio of active power to apparent power in an alternating current circuit.

In a Direct Current (DC) Circuit, the product of the RMS value of the electric current and the voltage is applied.

In an Alternating Current (AC) Circuit, the product of the current and the effective value of the voltage does not necessarily appear as energy.

In an AC circuit, the product of the electric current and the effective value of the voltage is called the apparent power.

An effective or available power is the product of the apparent power multiplied by the power factor.

The voltage or electric current of an AC circuit fluctuates in the shape of a sinusoidal wave so that the sinusoidal phases do not nearly match. If the difference in the phase angle is represented by φ, and the voltage by V and the current by I,

the value of the effective power becomes VIcos φ. Since the apparent power is V (Voltage) x I (Current), if the effective power is divided by the apparent power VIcosφ / VI = cosφ, it becomes the power factor that is usually represented in a percentage.

For example, if φ = 0 and cos φ = 1, then the electric power is at it’s highest; the highest value of the power factor is 1 and the lowest value is 0.

For electric appliances that use thermal energy, such as electric heaters or incandescent bulbs, the power factor becomes 1. However, the power factor becomes lower in the electrical devices that have coils such as electrical motor, transformer and condenser that converts electric energy into magnetic energy and electric devices such as capacitors, which store electrostatic energy. Therefore, we can say that the power factor is bad when the power factor is low.

The electric power we use in our daily life is usually representing a lagging power factor. The reason is because most electrical appliances such as air conditioner, fan, vacuum cleaner, laundry machine, and other motor electric appliances that consume large amount energy are products that represent the lagging power.

The GREENPLUG is a product that increases the power factor of the entire power system through our specialized condenser and series reactor. It significantly reduces the power loss by compensating the low lagging power factor close to 1.

Using a GREENPLUG will reduce the reactive power. When the reactive power decreases, the apparent power decreases also then the power factor increases.

Since the effective power value is fixed to VICOSφ, the current I and COSφ are inversely proportional.

If the power factor is improved by using the GREENPLUG, the electrical current will be reduced therefore, any energy loss (I2R) that may have result from it will also be reduced.

In our daily life, the amount of energy used for a certain period of time is more important than the energy used for a unit time.

Therefore, how much the kWh comes out by multiplying power and time is very important. Electricity charges are based on the amount of electricity, including any energy loss.

Using a GREENPLUG will reduce reactive current, reactive power, and apparent power because it improves the power factor and reduces the harmonics using the harmonic filter. As in result, the noise and heat generated by the appliances are reduced,

making the power more reliable.
