4kvA 54kV 132kvA 22-66kV 675kvA 270KV 1620kvA 75KV series resonance test device
Power frequency resonance complete configuration Reactor: connected in series with the subject to form LC series resonant circuit. Compensation capacitance: Compensates the subject with small capacitance to adjust the subject frequency. FM power supply: can change its output frequency, but also can change its output voltage. Excitation transformer: plays the role of coupling signal and voltage transformation, and raises the voltage according to its own changes. Capacitive voltage divider: Measures the voltage on the subject and feeds back to the FM power supply as a sampling signal.
