PURPOSE:¦To preent gas explosion, etc., by regarding the opening signal of the gaseous hydrogen sealing valve of a turbine electroic generator as an interruption signal, and by monitoring the consumption. CONSTITUTION:The consumption of gaseous hydrogen is calculated on the basis of gas pressure P1 and gas temperature T1 in an electric generator and atmospheric pressure B1 before the consumption and P2 and T2, and B2 after the consumption and meausrement time Tm showing the period of the gaseous hydrogen consumption. While gaseous hydrogen is sealed with a gaseous hydrogen sealing valve 4 opened, an interruption signal is generated through a digital input circuit DIo17 and an arithmetic circuit 12 performs the monitoring processing of the gaseous hydrogen consumption. Namely, whether a monitoring execution contact 100 or a gaseous hydrogen sealing valve contact 40 is made is discriminated. When the contact 40 is made, the monitoring of the gaseous hydrogen consumption is performed. |
