Always detects the temperature of the conductor (2) by infrared rays emitted from the conductor (2). For example, an excessive current may flow through the conductor (2), or the ambient temperature of the phase separation bus may rise abnormally. When the temperature of the conductor (2) becomes abnormally high, the temperature detection signal from the infrared temperature detection section (7) is processed by the signal processing section (10), and an alarm for informing the conductor temperature abnormality is issued. Further, in the case of a ventilation cooling type phase separation bus which cools the insulating space surrounded by the conductor (2) and the jacket (1) by blowing cooling air, for example, the cooling air is stopped due to a failure of the ventilation fan. When the temperature of the conductor (2) rises abnormally, an alarm is issued in the same manner as described above, or the output of the generator passing the load current through the conductor (2) is quickly reduced to reduce the load current.
