VACUFUSE® II SELF-RESETTING INTERRUPTER AND EDGERESTORE® UNDERGROUND DISTRIBUTION RESTORATION SYSTEM: IMPROVED TEST PROCESSES VacuFuse II interrupter and the EdgeRestore system represent some of the most advanced electrical technologies in the industry, requiring equally sophisticated manufacturing and testing to ensure safety and performance. Precision testing equipment plays a vital role in verifying key product characteristics. These testers measure factors like leak integrity and capacitance — critical indicators of long-term reliability. To ensure measurement accuracy and consistency, we conducted a Gage Repeatability and Reproducibility (Gage R&R) study across 19 testers. The study helped pinpoint testing process areas that could be more consistent and reliable, reinforcing trust in the results and supporting ongoing improvements. The team refurbished leak-prone chambers, redesigned endplates to eliminate bulging seals, optimized test methods to reduce reading noise, improved tester design to reduce mechanical noise, and implemented continuous vision learning. “These changes not only improved tester reliability but also deepened engineering teams’ understanding of the equipment — laying the groundwork for more accurate and efficient testing moving forward,” said Stephanie Hibicke, senior manager, quality assurance, lateral automation production.
