First, tried to sign up for Noreco's information as noted in the forum, without success. The big problem, for Dauin, for a week now, beginning around 6 am each morning, Noreco II voltage drops from 205V to around 120 by afternoon/evening. Essentially, that means no home power, stove, washer, occasionally computer, etc. for most of each day. A Noreco workman said it might be two months before repair is complete. Another said they had no idea. Would greatly appreciate some information. Thanks, billm
We are about 4km uphill from Dauin market. Presently showing 203v. Lowest I've ever seen it is 195v for a very short period. We have auto voltage regulators on fridge / tv etc and don't use aircon.
Good info but, if I were a member of Noreco II I would question why they have almost a 15% voltage drop over 30km (Amlan to Dauin - 69kV to 60kV) - a new transformer will not make up for the losses but just transfer those losses to the output voltage in direct proportion. I believe a 3% drop is the traditionally accepted norm. It all sounds like a lame excuse to me
I think you missed the part where they said. NORECO II general manager Fe Marie Tagle said in an interview Friday that the Dauin substation will be upgraded from 4.2 megavolt-amperes (MVA) to 10 MVA. The 4.2 MVA transformer is presently out of service while the 10 MVA transformer is being installed. That is why our power is temporarily diverted by way of Bagacay substation. With the new transformer the voltage variations due to load should be about 40% of what it was with the 4.2 MVA transformer online.
And Bagacay currently services the area through 2 x 50MVA transformers so my point is still valid - they have a 15% voltage drop from Amlan which will cause a directly proportional voltage drop to users. Bad lines, bad connectors and bad insulation is not going to be changed by upgrading a transformer. We have had the same issue in our Noreco I area for years - and upgrading the transformer x 2 didn't change anything here either. Bad transmission + insufficient capacity = significant voltage drops when everyone turns on their rice cooker
