Just a while ago, the following waveforms were captured from monitors in Jurong East and in the River Valley area, indicating a transmission fault, likely to be originating from the South block of Singapore. Waveforms captured in the River Valley area indicated a single-phase fault on L1 (Red) at 230kV transmission voltage.

Added the following screenshots obtained from a PQUBE, being monitored in South of Singapore, at Low Voltage. Thanks James!
