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...

The History Of Reactive Power Compensation If you are in the power industry, you must have heard of reactive power compensation. But you may not know much about it. What is reactive power compensation? We know that the power output of the power grid includes two parts: first, active power: directly consume electric energy, convert electric energy into mechanical energy, thermal energy,...
Power Quality Problems The automobile manufacturing industry is a typical heavy industrial industry, and its electricity demand has many characteristics, such as large electric energy demand, low power factor of electrical equipment, many typical nonlinear loads and impact load equipment, and high power quality requirements. Hazards and Influence In the traditional four major automobil...
Gelinmei (Wuxi) Energy Materials Co., Ltd. is a company that develops and produces lithium cobaltate and ternary materials. In the process of material production, some equipment (such as atmosphere furnace, air compressor, water chiller, etc.) will generate a large number of harmonics when working, which will do great harm to the whole power grid system. According to on-site data analysis and user...
Power Quality Problems Residential community power grids are low-voltage power distribution networks, generally connected to large power grids by 10/0.4kV transformers. Most of the loads in the grid work at three-phase 480V and single-phase 220V voltage levels, mainly small-capacity loads, such as air conditioners, refrigerators, and televisions. Machines and other household appliances. Most house...
YTPQC-AHF Active Harmonic Filter YTPQC-AHF Active Harmonic Filter is a perfect and comprehensive solution to the power quality issues of power grid, such as harmonics, reactive power and 3 phase load unbalance. YTPQC-AHF which is in parallel to power grid can detect the harmonic wave in power grid in time, generate the reverse-phase compensation current through the converter and dynamica...
Power Factor PF Measurement The control unit calculates: The power factor per phase PFL1, PFL2, PFL3, from the phase active and apparent powers. The total power factor PF from the total active power Ptotal and the total apparent power Stotal: PF = Ptotal / Stotal NOTE: Stot is the vector or arithmetic total apparent power, depending on the setting. This indicator qualifies:...
