After the operation of the low-voltage reactive power compensation and harmonic suppression device from Lidar Electric, the system power factor of the crystal furnace at Lens Technology (Hunan) Co., Ltd. improved from around 0.80 to over 0.95. The system current decreased from approximately 2500A to 1865A, the absolute value of the 3rd harmonic current distortion reduced from 300A to 56A, and the absolute value of the 5th harmonic current distortion decreased from 125A to 93A. This solution addressed the user's power quality issues and saved over 10% in electricity costs.

Client: Hunan Lens Technology Co., Ltd.
Project Background
Lens Technology (Hunan) Co., Ltd. was established in December 2006, with a registered capital of 30 million USD, located in the Changsha National Bio-Industry Base Lens Road. The production workshop covers an area of over 10,000 square meters, with a dust-free workshop area of 2,200 square meters, and a total of more than 800 employees. It has production equipment and processing technology for glass mold opening, profiling, thermal bending, cold grinding, polishing, strengthening, plate making, vacuum coating, silk screen printing, etc. It mainly produces high-quality glass lenses and PMMA lenses required for mobile phones, watches, MP3s, MP4s, digital cameras, electrical appliances, instrument panels, and decorations.
Electricity Overview (Crystal Growth Furnace)
The E1 plant of Lens Technology Co., Ltd. has a total of 3 transformers in the central electrical room, each with a capacity of 2500kVA, voltage level of 10kV/0.4kV, and the load is the crystal growth furnace. The power factor is about 0.80, and the absolute value of the third harmonic current distortion is 300A, causing equipment failures, leading to tripping, and resulting in product scrapping, with losses of hundreds of thousands of yuan for each scrapping.
Low voltage reactive power compensation and harmonic suppression deviceDesign Plan
