Product Description

Generator AC Resonant Test System with frequency inductance modulation technology

GDTF series AC Resonant Test System for Generators can be used by adjusting inductance of the reactor, or adjusting the work way of resonant frequency of the system to achieve resonance.You can also use both two methods to achieve resonance.In the voltage boosting process, if the resonant point deviate,you can find it exactly by the way of fine tuning frequency,which ensure a high Q value and reduce power capacity and volume weight of test equipment.
