Methodology (Con’t)
•A literature search summarizing the work practices adopted by utilities in maintaining (most washing) their lines. What kind of data do utilities monitor that help them decide when to wash (ESDD, leakage current, dust deposit gauges, experience, monitoring weather conditions, etc). How effective is live-line washing when compared to de-energized washing? how many utilities do live-line vs. de-energized? are these criteria dependent on the nature (chemical make-up) of contamination.
•Place dummy insulators and simple shape devices at various locations on the distribution system to begin field contamination phase.
•Develop and test simple diagnostic tool for contamination detection.
•Perform field measurements with diagnostic tools and compare accuracy with ESDD method on contamination assessment.
•Provide a detailed report summarizing the results of the project
