1. Electric power quality problems
The common electric power quality issues in the world power applications include harmonics, three-phase asymmetry, notch, voltage flicker, resonance transient, impulse transient, voltage transient, noise, etc. Among them, harmonic and voltage transient are the most prominent power quality problems. The annual economic loss caused by power quality disturbance and electrical environmental pollution is amazing.
The EPRI report of the American Academy of Electric Power Sciences points out that losses caused by harmonics and other power quality problems in the United States are as high as $30 billion a year. In China, according to the data of "China Power Quality Industry Status and Customer Behavior Survey Report" among the 92 enterprises in 32 industries surveyed, 49 enterprises suffered economic losses of 250-350 million yuan due to power quality problems.
At present, the international electricity utilization rate is about 56%, while our electricity utilization rate is only about 35%. The important reason is the low power quality. If the power quality is improved on a large scale to improve the efficiency of power utilization, it will play a very important role in energy saving and emission reduction.

The special winding mode cooperates with the principle of electromagnetic balance to enhance the balance degree of three-phase current and voltage, so as to enhance the smooth operation of electrical equipment, reduce the abnormal heating, luminescence, noise and vibration of electrical equipment, and then improve the mechanical efficiency, reduce the demand for electrical energy from the power grid, so as to achieve the purpose of energy saving and protection.
4. Technology Princip
Electromagnetic balance technology / Micro magnetic field technology / Virtual capacitance technology
The core technology of SEBOS Intelligent Power Saving System is a three-phase electromagnetic balance technology with iron core and special multi-winding connection mode. Its iron core adopts anti-Z connection, balances three-phase voltage and current, balances three-phase power supply and eliminates clutter interference by overlapping magnetic fields produced by three-phase windings.
Special multi-winding connection mode can compensate magnetic flux of iron core and control the consistency of induction electromotive force of each phase to the greatest extent, so as to maintain three-phase balance, reduce additional losses such as zero-line current, and achieve the purpose of power saving.
