Q: Dab tsi yog qhov txawv ntawm zaus -tuned thiab inductance-tuned resonance systems?
A: VFSR kho inverter zaus (20-300 Hz). VSR kho reactor core qhov sib txawv ntawm 50/60 Hz. Txhua tus muaj qhov zoo sib xws.

Hybrid systems: coarse tuning ntawm reactor kais + zoo tuning ntawm nqaim -band VFD (45–65 Hz).
Txoj cai ntawm tus ntiv tes xoo:
• Feem ntau cables <5 km → VFSR (30–300 Hz).
• GIS / luv cables ntawm 50 Hz → VSR (tsawg zaus).
• Kev hloov pauv siab tshaj plaws (cables + GIS + TX) → VFSR nqes mus rau 20 Hz.
