| 説明 | Sierra Nevada maintenance crew members hose down Tracy Substation east of Sacramento, California, during the annual wash the week of Sept. 21. The wash removes contaminants from nearby farms, wind, light rain, dust and animals deposited on the equipment over the year. Contaminants on energized electrical equipment degrade the conductive surface, allowing electricity to escape the equipment and cause flashovers and other damage. The Central Valley Project is particularly susceptible for contaminants as it provides water for more than half of the top 10 agricultural counties in California. (Photo by David Hahn) |
