As part of the procedure to restart a conventional power plant, the turbo-alternator was placed back into service on 15th October at 2 pm and then coupled to the electrical national network without any glitches. Between the evening of the 15th and the following morning, an abnormal temperature rise caused the self-ignition of oil in the oil tank and a fire around the turbo-alternator. Several remedial measures were adopted, namely: installation of a high-temperature safety feature, elimination of filters (limiting the oil flow rate), and a reminder disseminated to all control room operators regarding rounds to be carried out inside the unit. The introduction of automated mechanisms to facilitate the start-up and monitoring of heavy machinery during this critical phase gradually led to neglecting the precautions that in the past took field operators for several days to ensure that stable operating conditions had indeed been reached. Monitoring efforts involving filters, a range of temperature readings (especially thresholds) and listening for vibrations had generally enabled adopting remedial measures before the alarm announcing a near certain state of degradation.
