Background Hankook is a world famous tire brand from South Korea. Since entering China in 1996, the company has invested more than 600 million US dollars to establish a complete production, logistics and sales network system. It is a high-tech factory with an annual output of 10 million tires in Jiaxing, Zhejiang. Due to the low power factor in the on-site distribution system, the company urgently...
Power Quality Problems With the in-depth application of power electronic technology, the automation of the petrochemical industry has been continuously improved, and the nature of the load has also undergone qualitative changes. The increase of nonlinear and impact loads has brought about voltage flicker, three-phase imbalance, and excessive reactive power consumption. , harmonics and a series of ...
Background The input terminals of switching power supply and ups of Chinatelecom cloud computing Guizhou Information Park data center generate harmonic current, and the final harmonic current is collected on the general busbar. A large amount of harmonic current will cause the following harm to the communication room. Harmonic current will interfere with the communication signals of adjacent condu...
Power Quality Problems in Data Center Due to the uninterrupted power supply of the load in the data center room, a large number of UPS, switching power supplies and inverter air conditioners are used. The input stages of these devices are all three-phase arrangements, which generate a lot of harmonics when used. The switching power supply and UPS equipment first rectify the AC into DC, and then co...
Power Quality Problems There are a large number of power electronic components in medical equipment. The more common equipment are MRI (nuclear magnetic resonance apparatus), CT machine, X-ray machine, DSA (cardiovascular imaging machine) and so on. Among them, MRI will generate radio frequency pulses and alternating magnetic fields to generate nuclear magnetic resonance, and radio frequency pulse...
Benefits of installing YTPQC Active Harmonic Filter Prevention of breakdown and equipment failure Maximum utilization of installation capacity Improvement of energy efficiency Securement of reliability and continuity Reduction of service and maintenance costs Prevention/reduction of unnecessary energy losses Increased safety by reducing fire risk YTPQC-AHF Active Harmonic Filter YTPQC-AHF A...
Power Quality Problem By the end of 2020, China railway operating mileage reached 146,000 kilometers, and the high-speed railway operating mileage reached 37,900 kilometers, ranking first in the world. High-speed rail traction transformers generally use 12 or 24 pulse rectification, which will generate 11th and 13th harmonics; power distribution transformer loads mainly include inverters, UPS...
YT Electric single-phase active harmonic filter(AHF) is improved and upgraded on the basis of three-phase equipment. The A/B/C (L1/L2/L3) three-phase output is the same to achieve the purpose of single-phase compensation. Features of Single-phase AHF The device has a variety of compensation modes: reactive power compensation, harmonics current mitigation, which can be compensat...
