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...
Power Quality Problem The target enterprise produces shampoo, hair conditioner, moisturizing products, skin care products, liquid detergent, sanitary napkin, plastic molding products, cosmetics, washing powder, soap, etc. because the factory has more frequency conversion equipment, the harmonic current is large, and the voltage distortion rate is high, which endangers production safety and needs t...
Power Quality Problem Public utilities is indispensable to urban production and operation, residents' daily life, is the basis of urban survival and development and basic conditions, with the development and perfection of public utilities, improve the efficiency of urban labor, create a beautiful environment and good conditions for residents at the same time, also greatly increased the powe...
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:...
What is electricity? All matter in nature is composed of atoms, and each atom is composed of a positively charged nucleus and a certain number of negatively charged electrons, and the electrons revolve around the nucleus at high speed. Under normal circumstances, the positive charge of the nucleus band is equal to the negative charge of the electron band, so the general object is not charged. When...
