Equipment Failure: 50 Hz vs 60 Hz

Hi Guys,

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.'s picture

I am trying to find a neutral fault or failure underground about 2 ft in a conduit. What is the best tool to find it? Can anyone point me in the right direction?

While some equipment can run on both frequencies, it's obviously best to use a source that is rated for the equipment. I'm pretty certain you can buy easy to install frequency converters, but here is my 2 cents:

1) The surge protector has probably gone bad. People often think they last forever, but that is not true!

2) Using a 50 Hz frequency will have a lower voltage and a higher current compared to the 60 Hz frequency. The difference in electrical characteristics probably fried the equipment.

Your TV and cordless phone might have probably had SMPS type power supply capable of operating on both 50 and 60 Hz. So I vote surge protector failed.
