Vibration Method for Monitoring the Technical Condition of Support-Rod Insulators Using Non-Contact Laser Vibrometry Methods

A new method of non-contact vibration control of the technical condition of support-rod insulators, which are in operation under operating voltage, is developed. Theoretical studies were carried out in the ANSYS software complex to determine the information frequencies of natural oscillations of support-rod insulators associated with certain types of defects. A new measurement and diagnostic complex and software for implementing a new method for contactless monitoring of the technical condition of the support-rod insulators using laser vibrometry methods have been developed and created. Experimental studies of the parameters of natural oscillations of the of support-rod insulators on the operating substation under operating voltage have been carried out, and the operability of a new method for contactless monitoring of the technical condition of the support-rod insulators has been tested.
