1HS2858 Variable Frequency Series (Parallel) Resonance Test EquipmentOverview

Variable frequency string(And))The complete set of resonant testing equipment is based on the principle of series resonance, using an excitation transformer to excite the series(And)Connected resonant circuit, controlled by adjusting frequency conversion

The output frequency of the device causes series resonance between the reactor inductance and the sample capacitance in the circuit, and the resonance voltage is the voltage applied to the sample. The frequency conversion resonance test device is widely used in industries such as power, metallurgy, petroleum, and chemical engineering, and is suitable for the handover and preventive testing of high-capacity, high-voltage capacitive specimens.
