Sarita is that the local contractor that does work for Edenorte in your area? The fuses on the poles seem to be an ongoing problem where I live too. We had one catch fire not that long ago. Big problems when our local contractor company tried to fix that with a modified fuse that wouldn't fit properly. Sent a major spike down the lines that fried appliances and some of the buried house wires themselves. Fuses and transformers seem to be a persistent weak link in the system that do not get enough preventative maintenance attention.
Recently Sarita as been the main contractor used by Edenorte when a report is made with Edenorte. Over a year ago, when we were upgraded to 24/7 power, Sarita did the installation of the poles, wiring, transformers and lights. On what they did, they did well. On my street, they failed to put lights because they were told not to install any pole mounted transformers that could have fed power to the lights. We still have ancient ground mounted transformers with too many houses hooked to them. I have tried to have Edenorte complete the jobs of new transformers and lights, but the morons stonewall any response. At least power is now on 95% of the time instead of 10 hours a day like when I arrived in the DR. That is great great progress, but as usual it is that last 5% that simply cannot be reached.
If the fuses blow a lot, it is either from shorts in cracking high voltage lines during rainstorms , undersized fuses, corrosion from salt air, inadequate capacity in the lines or a combination thereof. We have had them all.
