Abstract:
The present application relates to an apparatus and method for detecting defects in composite insulators used in power systems. The apparatus includes a test frame, a hydraulic cylinder connected to a first end of the test frame for imparting a load on a composite insulator, a hammer for imparting excitations into the composite insulator, and a data collection device for collecting frequency responses traveling in the composite insulator as a result of the hammer striking the insulator. The composite insulator is secured between the hydraulic cylinder and a second end of the test frame.
