Abstract: It is an important part of the power system operation for the dry-type air-core reactor. This paper
investigates the experimental modal characteristics in the work condition based on the eigensystem realization
algorithm method. The result shows that the lower order resonance frequency of the dry-type air-core reactor
existed in the work excitation frequency, which was one of the most important reasons of the equipment damage
and noise enhancement during the work condition. The result provides the imperative data for improving the
resonance of the equipment.
Keywords: High voltage equipment; Dry-type air-core reactor; Experimental modal analysis; Noise control
