TESLA: Tough and Ecological Supercritical Line Breaker for AC

Project Innovation + Advantages:
Leakage from SF6-insulated circuit breakers and power equipment has been raising environmental concerns due to the high GWP of SF6. Georgia Tech proposes TESLA, an SF6-free high-voltage circuit breaker. Recent breakthroughs in the dielectric properties of supercritical fluid research show the promise of using it as a dielectric and arc-quenching medium for high-voltage AC circuit breakers instead of SF6. TESLA opens possibilities for an SF6-free electric apparatus. The team will design and build the proposed circuit breaker rated at 245 kV, 4 kA and validate the design and functionality using a synthetic test circuit.
