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...
What is power quality? The IEC (1000-2-2/4) standard defines power quality as follows: power quality refers to the physical characteristics of power supply devices that do not interrupt or interfere with users' use of power under normal working conditions. The most serious power quality problems are voltage sags and complete voltage interruptions. In fact, power quality refers to the...
Due to the rapid development of power electronic technology, the nonlinear characteristics of industrial and agricultural power loads, especially transportation and civil electrical products are becoming more and more serious, and the power factor of users is also declining. Therefore, reactive power compensation devices are more and more widely used. The power compensation device is used to suppl...
Three-phase lines are common: three-phase three wire, three-phase four wire The three - phase three - wire system is star connection neutral point ungrounded and Angle connection method, the general high - voltage power supply uses three - phase three - wire system, three - phase four - wire is star connection neutral point grounding, low - voltage system uses three - phase four - wire system. &nb...
Effect of Poor Power Factor The major effect of poor power factor is higher value of line current. We know that power factor (pf) is an important parameter for calculation of power in an AC circuit. For a given power and voltage, the current flowing through the line is inversely proportional to the power factor. This means that a poor power factor i.e. low power factor will result in hig...
With the development of society and the increase of demand for electricity, Reactive power compensation technology has developed rapidly, including Static VAR Compensation and Dynamic Reactive Power compensation, and has gained rich operating experience. However, some problems have also been exposed in practice. Some reactive power compensation devices are inconvenient to move, and the equipment m...
What is EMC testing EMC test (Electro Magnetic Compatibility) refers to the comprehensive evaluation of electromagnetic interference (EMI) and anti-interference capability (EMS) of electronic products. It is one of the most important indicators of product quality. The measurement of electromagnetic compatibility consists of test sites and test instruments. The purpose of EMC test is ...
