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...
Electricity is a big part of our day, powering all the tech we use. There are two main types of electricity users, or "loads," called linear and non-linear. This just means they use electricity from the power supply in different ways. This distinction affects everything from power efficiency to the longevity of devices. Categories of Electrical Loads: · Inductive Loads: Characterized b...
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...
3 phase load current imbalance In three phase systems, current unbalance is defined as the maximum deviation of any phase current from average divided by average current. Current unbalance can occur due to reasons within the control of the end user or outside the control of end user. Some of the reasons for current unbalance (or imbalance) are: Source voltage from the electric utility is unbalance...
