Detuned Reactor
The growing use of power electronic devises is causing an increasing level of harmonic distortion in the electrical system whichvery often leads to problem with capacitor installations.
GAE FILTER CIRCUIT REACTORFOR GENERAL APPLICATION
The growing use of power electronic devises is causing an increasing level of harmonic distortion in the electrical system whichvery often leads to problem with capacitor installations. This is the reason why more and more energy suppliers demand the installation of detuned capacitor systems.
A detuned capacitor system performs the function of power factor improvement whilst preventing any amplification of harmonics currents and voltages caused by resonance between capacitorsand inductances in the electrical system.
By adding an appropriately rated series reactor to the power capacitor, both elements form a resonant circuit with a resonant frequency belowthe lowest order harmonic in the system (usually the 5th).
All frequencies above this resonant frequencynow see this circuit as inductive hence the 5th).
All frequencies above eliminating the possibility of dangerous resonances being set up between the capacitors and system inductances.
Our filter reactors are made of high-class transformer sheets and copper coils. They are dried and impregnated in a vacuum with enviromentally-friendly, low-styrole resin which ensures they can withstand high voltages, have low noise levels, and long operating life. Depending on their rated power, the reactors are provided with either terminal blocks or terminal lugs/cables. An integrated thermal switch (reversible) allows external monitoring and/or disconnection of the reactor in the event of impermissible build up of heat.
