Defects in Nonceramic Insulators: Can They be Detected in a Timely Manner?

From Ofil Ltd.

Introduction: There are a multitude of designs, materials, formulations, and manufacturing processes that are used presently for nonceramic insulators. While this beneficial in terms of offering choices for the users, this also means that in case of problems, failure patterns could be different. It is fairly well known that most problems in NCI result originate from interfaces. The critical interfaces in this type of insulator are between the rod and housing, between hardware-rod-housing and different sheds of housing if unit is not manufactured in a single piece.
