Muara Putus MPR Observation Report Dec 19, 2011
Dear colleagues,
Some problems had occurred during MPR observations on December 19 afternoon. Anyway, the condition had been recovered to normal, and the observation could continue until this report is made.
13:05 LT - PLN power fault (blackout) for about 5 seconds. Tx stopped. The observation restarted at 13:20 LT.
13:25 LT - PLN second blackout, for about 5 seconds (again). Tx and ACU stopped. ACU error status, AZ servo drive (internal software) error.
13:30 LT - ACU error recovered by switching ON and OFF the Radar Cabinet Main Breaker.
13:35 LT - PLN third blackout, just after TX preheating process finished. The blackout was longer. Genset started but then stopped after several seconds due to oil pressure fault. MPR stopped completely. I visually could see the thunderstorm occurred around Tiku area (from MPR site).
