Product Information

Applications

Enerkeeper a patented invention based on the state-of-the-art technology and incessant research efforts, which reduces the electricity consumption by around 15%. Enerkeeper-a power saving device can be setup for commercial, institutional and industrial usage.

During the use of electric equipments or appliances, the energy-wasting factors like ubalance, harmonics, and reactive power occur and lead to electric losses with rise in power consumption, low efficiency, and higher maintenance costs by shortening the lifespan of many electrical equipments.
Enerkeeper eliminates the energy-wasting factors, improves the quality of the power supply, and considerably reduces electrical bills, lengthening lifespan of the electrical equipments.

This innovative device is installed at the output of a transformer or a main circuit breaker. It works effectively and efficiently at any level of electrical load by improving power quality, reducing harmonics and phase current imbalance. Furthermore, this device yields good performance with just one unit whereas other compared products require a combination of two or more units. In fact, Enerkeeper is the only power-saving device that focuses on the majority of power quality problems for the total electrical load of small to large facilities.

Functions and Effects

Patented Technology

The EK ATW(Auto-Transformer Winding) technology helps in eliminating the unbalance, hamonics, and reactive power by offsetting the zero-phase current in each phase. As shown in the below in the diagram, the first coil is wound around the first and secone legs, and the third coil is wound around the third and first legs. In each phase, these coils should be wound in the opposite direction before connection to the neutral wire. This make out to keep constant magnetic-flux and opposite direction of the current flow in each phase and automatically reduces the distorted-wave-form currents, which are harmonice current and unbalance current.

Basically, an alternative current takes the form of sine wave, but as there is more increase in unbalance and harmonics, the basic sine wave form turns distorted, resulting an consumption to keep the constant output. The frequent occurrence of unbalance and harmonics results in an increase in current consumption, power consumption and highter resistance.

Enerkeeper is designed to eliminate the energy-wasting factors using the "zigzag" winding technology, increases the efficiency of electric equipments, and reduces the power consumption.

Harmonics

As electronic power controllers are used more, a rapid rise in nonlinear loads have been triggered, and the resulting harmonics has caused unexpeted electirc disturbances in the power supply systems.

Load types causing harmonics
Problems Arisin from Harmonics
  • Motor speed controllers
  • computr systmes, Rectifiers, and medical instruments
  • electronic Lighting Ballast
  • Electric are furnaces and electric welding machines
  • Factory Automation controllers
  • UPS
  • Transformers with magetic saturation
  • Overheat and overcurrent in the neutral-line conductor
  • Overheat, vibration, and noise of the transformer
  • Overheat, vibration, and frequent failure of the induction motor
  • Overheat and failure of the capacitor for correction of power factor
  • Disturbance and noise of PC and communication cables
  • Malfunction of protective devices

Unbalance

Equipment Unbalance

According to the Article 115 of the Indoor wiring Regulation of the Korea Electric Association;

  • 1-phase 3-wire type of low-voltage power -receiving units : 40% or less
  • 3-phase 3-wire or 3-phase 4-wire type of low-/high-voltage power-receiving units : 30% or less

3-Phase Load Unbalance

According to the codes and standards of the US National Electrical Manufacturers' Association,

  • A voltage unbalance of 3.0% results in approximately a 10% decrease in the capacity of the inductive motor; and
  • A voltage unbalance of 4.4% leads to approximately a 20% decrease in the capacity of the inductive motor

Reactive Power

An increase in reactive power causes a reduction in transmission capacity compared to apparent power, resulting in a transmission loss. Accordingly, there is a naturally increasing loss in the electric generator or transformer. Then offset compensatons are generally taken as the action to improve power factor by using another reactive power of an opposite direction. The improvement of power factor provides many cost-effective advantages such as a reduction in electricity rates and a decrease in power consumption and transformer capacity.
