Variable Frequency Series Resonance System MCZYXZ01
VF Series Resonance System
General introduction
This system adopts series resonance principle, through adjusting output frequency of inverter, it make
series resonance happen between reactor induction L in circuit and test object capacitor C, resonance
voltage is the voltage applied on test object.
Widely used in power, metallurgy, petroleum, chemical and etc.
Suitable for handover test and preventive test of large capacity & high voltage capacitive object, such as
generator, power transformer, GIS, high voltage cable, instrument transformer, and bushings.
Features
1) Advanced frequency adjustment and voltage regulation software technology
2) High stability and reliability
3) High frequency adjustment resolution
4) Large resonance voltage and frequency range
5) Low waveform distortion
