YTPQC-AHF Active Harmonic Filter is a comprehensive and flexible solution for power quality problems. It provides the advanced control and proven reliability that your facility needs to solve power quality issues. It monitors the load current and very quickly responds to the power system distortion as it develops. A corrective current is injected to effectively cancel out the harmonics required fr...

Passive Harmonic Filter The simplest of all filters are the ones built using just resistors, capacitors and inductors. Such filters are called passive harmoinc filters, as they are constructed from passive components. In electronics, passive components are those which do not produce energy of their own. They are only capable of dissipating energy (in the case of resistors) or storing energy (in th...

YTPQC-AHF Active Harmonic Filter can realize 2nd to 50th harmonic compensation with full compensation or seletive compensaton, output compensation current follows the system harmonic variation, devoted to green power quality. Our AHF's compensation capacity(ratio) can be set freely by the customers, to realize harmonics compensation, reactive power compensation or imbalance compensation.   YT...

Why power factor is lower at power grid with solar? The active power and reactive power consumed by the system is fixed. When there is photovoltaic, photovoltaic provides active power, so the active power provided by the system decreases, and the reactive power remains unchanged, so the power factor decreases. If the active power provided by photovoltaics is close to the active power consumed by t...

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...

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...

Low voltage automatic contactor switched capacitor banks or filter banks typically use a delay time of 30 – 40 seconds between steps. This delay time is chosen to ensure that the capacitors have discharged prior to being re-connected. The long delay time limits the autobank’s ability to track rapidly changing loads. The slow response time may result in an overload condition in filter b...

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...
