In the view of the electromagnetic force driven vibration of the filter reactor in HVDC transmission

which may cause environmental noise pollution

the overall vibration of the reactor is explored. Based on the laser Doppler vibration measurement technology

a vibration testing system of dry-type air-core reactor is constructed to realize vibration test under strong electromagnetic field environment. Different positions on the multi-layer encapsulation of the reactor are selected as test points

and corresponding test schemes are proposed by constructing the optical path.These test points are measured to obtain their radial vibration and axial vibration

and the vibration of the spider is also measured. The results show that the proposed test schemes are feasible

and may provide the foundation for following study of the vibration and noise mechanism of the dry-type air-core reactor.
