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...
