Oak Ridge National Laboratory is developing a probe to accurately detect direct current, or DC, energy in electric vehicles and rooftops with solar panels. That is expected to help ensure the safety of first responders and electrical workers.

“With more volts than ever before in electric vehicles and on solar-paneled rooftops, first responder and electrical worker safety is a growing concern,” ORNL said in a story published on its website on Monday. “Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory are addressing the challenge with the development of a probe to accurately detect direct-current energy.”

The DC “Hot Stick” probe is designed under the sponsorship of the U.S. Fire Administration, a division of the U.S. Department of Homeland Security. Not only does the DC “Hot Stick” detect DC voltage, but it also ensures that the probe is properly tapped into the electrical lines being tested, said the story, written by Stephanie G. Seay.

“The latter is essential because false negatives may be obtained if a meter is not making proper contact, noted ORNL lead scientist Bruce Warmack of the Electrical and Electronics Systems Research Division. [Read more…]
