Dry type iron core series reactor is an important element in reactive power compensation device and plays the role in protecting capacitor bank and eliminating grid harmonics. Incorrect use or configuration will easily cause very serious consequences and likely results in harmonic enlargement or damage reactor. In this paper, the damage of dry type iron series reactor during operation in the power system is introduced, simple analysis on normal vibration of reactor is made, the reason on abnormal increase of noise of the series reactor is found out and corresponding solution is proposed, which can provide reference to the operation and maintenance staffs.
