Variable Speed Drives (VSDs) Do you have AC motors in your facility?Do these motors need a variable output? The growing popularity of Variable Speed Drives (VSDs) is a key driver of energy efficiency, but Variable Speed Drives cause power quality problems, one of which is the harmonics within power systems. So networks requires more effective means to mitigate harmonics. In C...
Capacitive reactive power The reactive current of the load is generally inductive, so we can use capacitor bank to compensate it. However, the reactive power generated by loads such as UPS and charging pile is capacitive. Capacitor banks cannot compensate capacitive reactive power, so the latest reactive power compensation technology SVG Static var generator needs to be used to compensate cap...
Does Active Harmonic Filter can saving energy? YTPQC-AHF Active Harmonic Filter can save energy by reducing the amount of harmonic distortion in a power system. Harmonic distortion can cause power losses and reduce the efficiency of electrical equipment, so reducing it can help to save energy. How does active harmonic filter save energy？ YTPQC-AHF Active Harmonic filters can save energy by ...
Site conditions The site is located in Hangzhou Asian Games Village.The project has more than 20 power distribution rooms. Due to the main load being fire-fighting facilities, which are generally not started, the transformers almost all operate without load, and the cable length is long, resulting in capacitive reactive power at both the high and low voltage sides, which cannot be compensated by t...
Reactive currents backstreaming from Solar to Utility Reactive currents backstreaming(from Solar plant) in power supply system is not only harmful but also expensive for financial purposes. Parasite currents in both electricity transmission lines and equipment of solar power-stations cause financial losses because of converting electric energy to thermal (thus making generation amount lower, that ...
Power Quality Power electronics make modern life possible and enable all other areas of innovation. Although stable power delivery seems like a simple problem, the design of a high-efficiency power transmission and conversion system is prone to several problems that reduce efficiency by reducing delivered power. Nonlinear components are needed in power electronics to control the flow of power and ...
Achieving capable factory functional test requires meeting multiple criteria to ensure the highest quality product. These criteria include test capability and repeatability, system upgradability and supportability, and production scalability. Setting up new production test not only involves implementing new test systems, but also managing schedule risk and budget which are often impacted by techni...
YT ELECTRIC has been offering a comprehensive range of key components for Automatic Power factor correction (APFC) and power quality solutions for many years. The rapid development of industry and infrastructure resulted in the increased usage of power electronic loads which demands a highly dynamic response time for reactive power compensation. Conventional reactive power compensation only with p...
