PROBLEM TO BE SOLVED: To provide a steam turbine apparatus, in which a protection device that has been operated can be detected, without disposing additional devices to each protection device. SOLUTION: The steam turbine apparatus 2, unlike the prior art, utilizing a status signal generating portion 5 and an over-speed signal transmitting device 4 receiving a rotational speed signal S95 and outputting an over-speed signal S4 that becomes high voltage when the rotational speed of a turbine axel 92 exceeds a limit value. The status signal generating portion 5 receives a low oil pressure signal S7 of low pressure oil for emergency stop, an over-speed signal S4, a low oil pressure signal S84 of lubricating oil pressure, and an electrical signal S62. By combining these signals to perform logical processing, the status signal generating portion 5 generates a status signal S73 on over-speed trip, a status signal S74 on thrust abrasion trip, a status signal S75 on low pressure trip of lubricating oil, and a status signal S83 on operation of electric protection device.
