Apparatus and method of vibration testing for manufacturing defect detection in composite insulators

摘要

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.
