Proof Testing of Porcelain Insulators and Application of Acoustic Emission
An investigation of proof testing has been conducted on large cone and post porcelain insulators. The cone configuration was unsuitable for overload proof testing to the loads needed for effective lifetime predictions. The only merit of subjecting this configuration to a proof test is the assurance of no immediate macrocracking during installation. This is achieved by testing to a load marginally larger than the service load. Conversely, the post configuration exhibited the basic prerequisites for effective proof testing but detailed stress analysis of this system is needed before specific proof testing procedures can be recommended. Finally, acoustic emission measurements were a major asset for monitoring both macrocracking events and stress development during the proof tests.
