I just find it hard to believe that a company as large as the CFE, which supplies power to all of the country including homes, businesses, hospitals, etc, could have such power surges.
Hi Chris, Hi Juan,
There are many reasons for power surges. It is not necessarily that their generation plant put out more juice. They have lots of power lines and transfer stations and transformers and all kinds of equipment along the system. Things can happen. Of course they have voltage regulators at power plants and transfer stations and a transformer is a type of voltage regulator - transforms the power in the power lines to usable power for our equipment. All of this stuff will vary depending on where you are - not just in Mexico but anywhere. Variations anywhere in that system can relay through the system to cause variations somewhere down the line. Even in the US there is a lot of talk about the whole power grid and what bad shape it is in and how much needs to be done to improve infrastructure. So there are lots of reasons it could be CFE. I have no idea about the whole CFE system - for all we know their grid could be in better shape than in the US.
BUT - I do agree that most electrical problems in Mexico for RVers are caused by bad wiring in the parks. Many parks are just not built or design and installed for the size and requirements of today's RVs.
THAT SAID - I can show you businesses and houses all over Mexico that have ISB Sola Basic voltage regulators. These businesses and houses did not install them for no reason. Maybe a good electrician talked them into it. But there must be a reason. So it would appear there are voltage fluctuations in places other than RV parks. If it were just to protect computers they could get a basic UPS with AVR to cover the computer. But they put them in for the entire building. They must have reason to think these devices might come in handy.
I don't think CFE - or many other companies - are going to release PR news items saying they have problems. They want us all to think everything is all well and good.
