How Can Workers Touch Live Power Lines and Survive?

This worker is touching a live power line. The power is still on. So why isn't he electrocuted? Discover how specially trained crews perform live-line barehand work—and why a protective suit contains metal that conducts electricity. Why isn't being airborne enough? What happens when a helicopter approaches an energized conductor? And why can another nearby wire still be deadly? This video connects those questions to voltage difference, electric fields and the engineering behind live power line maintenance. We also explore what crews actually repair, including a documented project on an energized 500 kV transmission line, and the small components that help power lines survive years of vibration.
