Article: Design and Construction of an Advanced Tracking Wheel for Insulator Materials Testing

Authors: Harrison P. Fletcher, Andrew Macdonald, Chris Secord, Mark Lenckowski, Rajkumar Padmawar, Dennis K. Hore

This account details the design and construction of a sophisticated tracking wheel for the accelerated aging of polymer insulators by subjecting them to surface contamination and high voltage. Automated control of wet-dry cycles is achieved by means of a computer-controlled lift mechanism that operates in tandem with the rotation. The applied voltage is continuously variable and can accommodate insulators of mixed lengths.
