Johns Hopkins Students develop device to protect workers from Arc flash

Johns Hopkins Students develop device to protect workers from Arc flash

Three students on an Engineering Design Project course at Johns Hopkins University undertook a challenge from the Baltimore Gas and Electric Company to develop a method to disconnect power lines from residential transformers at a safe distance, beyond the range of dangerous electrical arcs. Currently, utility workers must wear protective gear and use an 8-foot- long "hot stick" to disconnect…
