GAS LEAK DETERMINATION DEVICE, GAS LEAK DETERMINATION PROGRAM, AND GAS LEAK DETERMINATION METHOD

摘要

A gas leak determination device according to an embodiment comprises an absolute pressure information acquisition unit, temperature information acquisition unit, temperature correction factor calculation unit, conversion unit, and determination unit. For each gas section, the absolute pressure information acquisition unit acquires absolute pressure information indicating the absolute pressure of the gas section. The temperature information acquisition unit acquires temperature information indicating a tank surface temperature. For each gas section, the temperature correction factor calculation unit calculates a temperature correction factor for correcting the temperature of the gas section on the basis of the temperature information acquired during a prescribed period and the absolute pressure information acquired during the prescribed period. The conversion unit converts the absolute pressures of the gas sections into absolute pressures at a prescribed standard temperature on the basis of the absolute pressure information and the temperature correction factors calculated by the temperature correction factor calculation unit. The determination unit determines whether there is a gas leak of insulating gas from a tank on the basis of the absolute pressures at the prescribed standard temperature that have been arrived at through conversion by the conversion unit.
