GRT-APF series
The GRT-APF series active power filter uses instantaneous harmonic generation technology to detect the harmonic current content on the load side, generate currents of equal magnitude and opposite phase to the load harmonics, and cancel out the harmonics. The GRT-APF series active filter is designed based on a fast harmonic detection and compensation control algorithm, which can quickly respond and effectively filter out the 2-50th harmonics generated by nonlinear loads.
GRT-SVG series
The GRT-SVG series static reactive power generator is mainly used for reactive power compensation, improving power factor, and optimizing power quality. The GRT-SVG series covers specifications such as 20kvar, 30kvar, 50kvar, 75kvar, 100kvar, 150kvar, etc., with continuously adjustable compensation output, which excellently solves the shortcomings of traditional reactive power compensator step compensation.
GRT-ASVG series
The GRT-ASVG series filtering type static reactive power generator is based on a dual digital signal processor (DSP) as the core, and a self commutation bridge circuit is connected in parallel to the power grid through a reactor. Real time data acquisition technology and dynamic tracking technology are used to continuously monitor the voltage and load current of the power grid and system. Through a series of calculations by the internal DSP, the reactive power and harmonic components of the load current are extracted. Finally, the compensation current is output to the system through a converter unit with IGBT as the core, achieving the purpose of reactive power compensation and harmonic filtering.
Good filtering effect
Active power filters output waveforms with opposite phases to cancel out harmonics.
Smooth reactive power compensation curve with no range adjustment
It can quickly and indiscriminately absorb or release reactive power, and the power factor can be compensated to close to 1.
Double air duct layered design
The air duct design is more unobstructed and the heat dissipation efficiency is higher;; The operating temperature of the device decreases, resulting in a longer lifespan.
Vertical wound inductor
Using copper foil vertical winding process reactor, the temperature of the same capacity coil is reduced by 40°C, significantly reducing temperature rise and further improving safety performance.
Distributed modules address small capacity requirements, installation in narrow spaces, and distributed compensation at the end of power supply and distribution lines
Distributed modules can be used for reactive power compensation, harmonic control, and three-phase imbalance adjustment at the end of the line, improving power factor and reducing cable losses. Widely used in special occasions such as charging stations and cable distribution boxes.
Adopting on-site methods for source control of harmonics or reactive power can fully reduce the impact of harmonics and reactive power on the system and save investment.
The specifications of distributed active filtering modules cover 15A/25A/30A.
The specifications of the distributed SVG module cover 10kVar/15kVar/20kVar.
Distributed modules are usually wall mounted models, fixed in hard walls or cabinets by upper and lower edges.
Plug in installation avoids power outages caused by equipment maintenance failures and reduces maintenance costs
Plug in modules are mainly used in low-voltage distribution intelligent JP cabinets, which can be used for reactive power compensation, harmonic control, and three-phase imbalance adjustment. The modules are installed in a plug-in manner, avoiding power outages caused by equipment maintenance or faults and reducing maintenance costs.
The specifications of plug-in active filtering modules cover 35A/15A/50A.
The specifications of plug-in SVG modules cover 25kVar/30kVar/35kVar.
Modules are usually installed vertically.
