Abstract:
When a high impulse current flows through a conductor, the conductor may be melted due to the current value and duration. A straight moderate copper conductor such as 1mmφ is melted by a relatively small DC current in hundreds of amperes due to the steady thermal transfer from the surface of the conductor to the ambient. Moreover, a thin conductor such as 0.1mmφ is melted by a relatively large impulse current due to the specific melting Joule integral: (j²t)m in an adiabatic condition an...     »
