1. A system for detecting a failure condition in one or more components of a wind turbine, the one or more components comprising a first component and a second component that is different than the first component, the system comprising:
an impact device disposed on the first component of the one of the one or more components and configured to selectively generate an impulse in or on the one or more components, wherein the impact device is mounted in a bracket, and wherein the bracket is removably couplable to the first component of the one or more components via a magnetic connection;
at least one sensor disposed on the second component of the one of the one or more components and configured to provide data indicative of vibrations in the second component of the one or more components; and
at least one controller communicatively coupled to the impact device and the at least one sensor, the at least one controller comprising at least one processor, the at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
actuating the impact device to generate a vibration having a frequency and a magnitude in the one or more components;
receiving, via the at least one sensor, data indicative of the frequency and the magnitude; and
determining whether the data indicative of the frequency and/or the magnitude is outside of a predetermined vibration range for the one or more components;
wherein the one or more components comprises a hub and a pitch bearing coupled to the hub, wherein at least one of the impact device and the sensor are disposed on an interior surface of the hub, and wherein the other of the impact device and the sensor are disposed on the pitch bearing.
