I just need some views on this matter. I'm writing from Jamaica where electricity is generated at 50 Hz. I bought two pieces of electronic equipment (a smart TV and a cordless phone) from the U.S. last year (manufactured for 60 Hz), as I typically do. Both pieces of equipment were on a surge protector. The thing is that over the course of about 2-4 weeks, there were a number of outages (lasting less than 3-5 secs, typically more than 4 times per day) and both pieces of equipment failed to work properly after a time, while other older 60 Hz specific equipment continued to work at the same location. Both pieces of equipment were working fine for at least 8 months.
I am just wondering which would have had a greater impact on the equipment failure; the multiple unexplained outages per day or the frequency of the distributed current (50 Hz when equipment was made for 60 Hz)?
Your thoughts are greatly appreciated.
