Localized Voltage Dip 26-09-2015 0736hrs

Earlier in the morning today, there was a localized voltage dip (dip by ~ 80%) in the Jurong East area. From the waveforms captured, it can be inferred that there was a 22kV L3-L1 fault.
Sensitive equipment was likely to be affected, especially those sensitive single phase LV control circuits taking in on Phase L3.
