Voltage Disturbance – 10-9-2014 1919hrs

Earlier, our office recorded a ‘shallow’ dip at approximately 1919hrs.  Tell-tale signs from other neighbouring monitoring sites show this could be a transmission-level fault. Shall await for the report from the utility tomorrow.

Update 15/9/2014 from the Utility: Customer installation fault at Jurong Island

Noting how this dip due to a ‘customer installation fault’ can be seen in many areas, those ‘in the know’ will know who is the Customer here.
