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:...
Power cabinet The complete power distribution device is a complete set of devices supplied by the manufacturer. According to the requirements of the main wiring, the manufacturer assembles the electrical equipment of each circuit, including control appliances, protection appliances, measuring appliances (such as circuit breakers, disconnectors, mutual inductors, etc.), bus bars, current carrying c...
Introduction To Capacitors And Reactors Reactance includes inductive reactance and capacitive reactance, and reactor includes inductive reactance (inductor) and capacitive reactance (capacitor). Inductance has the function of "blocking AC and blocking DC", that is, in the AC circuit, the characteristics of inductive reactance are used to "pass low-frequency DC and block high-frequency AC". The cap...
