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 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...
YT Electric TTU reactive power compensation project This is a reactive power compensation project of the distribution station in the community with TTU (Distribution Transformer supervisory Terminal Unit) function completed by Yingtong electric. In the power supply and distribution system, the distribution transformer monitoring terminal (TTU) is used to collect and control the information of the ...
SVG Compensation YTPQC-SVG Static VAR Generator, IGBT switching compensation systems consist of high technology IGBT drivers and modules. SVG can perform both inductive reactive and capacitive reactive compensation in both directions. YTPQC-SVG compensation systems are designed for facilities with fast load change, where the reactive power limit is very important, and thanks to high speed and sens...
YTPQC-SVG Static Var GENERATOR Static Var Generator SVG works as a dynamic reactive power source, adopts high-speed computation components like DSP/IGBT, combining with super precise control program, following the grid current variation in real time, improving Power Factor value to 0.99 within 5ms. SVG represents the latest generation technology in the power factor correction field. By elimi...
The inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but there is only one winding, which only hinders the change of current. If the inductor is in the state of no current passing through, when the circuit is connected It will try to hinder the flow of current through it. If the inductor...
