Abstract

This dataset includes design files and testing demos for a hand-operated device and a motorized device for preparing twisted pair specimens used for partial discharge (PD) testing, under the scope of a NASA EPSCoR R3 project on acoustic detection of PD. The devices were developed following ASTM D2307-21. The hand-operated unit was developed by Danniel Curl. The motorized unit was developed by a 2025 - 2026 Capstone Project team in the Department of Mechanical Engineering at the University of Arkansas, including Ty Merseal, Ethan Lett, Tanner Youngblood, Luke Allison, and Rowan Swendner, advised by Prof. David Jensen. Acoustic testing of PD in twisted pairs was performed by Stephen Pierson. The team appreciates the guidance from Dr. Timothy Krantz and Dr. Thomas Tallerico at the NASA Glenn Research Center.
