The transition to normal state in a vertical second generation high-temperature superconducting wire with alternating current was investigated experimentally at liquid nitrogen level decrease below the top end of the wire. The transition was shown to occur in a jump-like manner at a certain length of the external part of the wire and it is reversible. The stages of the transient were determined. The methods of heat balance recovery after such transition were suggested and realized. Feasibility of using the obtained results to develop an emergency level sensor for liquid nitrogen was pointed out. Keywords: superconducting wire, liquid nitrogen, level sensor, transient, heat balance.
