Abstract
This contribution describes a new technique to diagnose faults with high-voltage components in electrostatic accelerators. The main applications of this technique are non-invasive testing of high-voltage grading systems; measuring insulation resistance or determining the volume and surface resistivity of insulation materials used in column posts and acceleration tubes. A simple and practical fault finding data interpretation procedure has been established based on simple concepts. As a result of efficient in-situ troubleshooting and fault elimination techniques, the relative resistance deviation ΔR/R is kept below ±2.5% at the conclusion of maintenance procedures. In 2015 the technique was enhanced by increasing the test voltage from 40 V to 100 V. Experimental verification of the improved resolution was conducted during recent scheduled accelerator maintenance in May-June 2015.
