After the operation of the dynamic capacitor compensation cabinet - low-voltage dynamic reactive power compensation and filtering device TSFGD, the system power factor improved from around 0.83 to over 0.95. The average operating current of the system decreased from 820A to 580A, solving the user's power quality issues and saving more than 10% on electricity costs. It enhances the power factor, suppresses harmonics, and reduces system current, improving the quality of electricity usage.

Project Background
PanasonicPanasonic Wanbao (Guangzhou) Compressor Co., Ltd., PWAPCGZ was established on June 8, 1993, and officially started production on January 1, 1995. The investment ratio is: Panasonic Electric 69%; Wanbao Group 31%, with a registered capital of 113.84 million USD, covering an area of about 252,000 square meters, and employing about 5,000 people. The main products are rotary compressors for room air conditioners and automotive air conditioners, with a production capacity of 12 million units per year. In April 2003, it officially entered the automotive air conditioning compressor manufacturing field, producing three major series: H, G, and V, with an annual output of 500,000 units. It is one of the five major production bases of the Panasonic compressor group.
Electricity Overview (Automobile Manufacturing)
PanasonicPanasonic Wanbao (Guangzhou) Compressor Co., Ltd. has a transformer with a rated capacity of 1000kVA, voltage level 10kV/0.4kV,The main load ismultiple single-phase spot welding machines.。The spot welding machine can have a maximum impact current of1820A (the rated current of the transformer is 1443A), and the three-phase current is severely unbalanced, causing signs of magnetic saturation in the transformer core, excessive noise, severe temperature rise, and a power factor in the range of 0.4 to 0.8, frequently triggering the transformer current protection.。
