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...
What are scenarios causing power factor displacements 1. Poorly designed electrical systems with inadequate power factor correction equipment. 2. Large inductive loads such as motors, transformers, and generators that cause lagging power factor. 3. Unbalanced three-phase loads that cause phase displacement of the current and voltage waveforms. 4. Unbalanced single-phase loads that cause current an...
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 ...
YTPQC-AHF Active Power Filter has been operating safely and stably in France YTPQC-AHF Active Power Harmonic Filter is an advanced power quality control equipment, which can compensate reactive power ,harmonics current and imbalance by setting parameters from friendly Human Machine Interface.This time French client purchased our Active Harmonic Filters mainly to improve Power Factor and mitigate h...
The reactive power consumed by the transformer is generally about 10% to 15% of its rated capacity, and its no-load reactive power is about 1/3 of the full load. Therefore, in order to improve power factor (PF) of the power system, the transformer should not operate at no-load or in a long-term low-load operation state. Vigorously improving the power factor of transformers, reducing line losses, a...

Hybrid power factor correction Hybrid Active power factor correction systems utilise power electronics and digital control to achieve active reactive current compensation for specific and high performance solutions. YTPQC hybrid power factor correction system is comprised from both capacitor based and Static Var Generator(SVG,Active Power Factor correction). Static Var Generator is use...
Harmonics and 3rd order harmonic Harmonics are the result of nonlinear loads that convert AC line voltage to DC. Harmonics flow into the electrical system because of nonlinear electronic switching devices, such as variable frequency drives (VFDs), computer power supplies and energy-efficient lighting. Today, the most prevalent and growing harmonic sources are: VFD’s, EC motors...
