Electricity
While i am wide open on the elect subject jou folks that have flucuafion problems ( electric flucuations )grin next time you are in the states
or a home depot get a couple of 10% booster transformers or a 20% one for e special circuit to run your appliances on motors don,t like to low a
voltage and they express thier displeasure by smoking and sparking for some reason 10 0r 20 % higher is good for them but no more than that ,
folks in the const industry that used power tools used these transformers so as not to burn up thier tools , remember 10 to 20% boost no more than
that ,, that is my lesson for the day i hope it saves some of you from having to by a new appliance so you will have some money to buy me a
margurita some day jim g

Lencho a elect load is measured in watts and is constant and is a prodcct of volts times amps if you have a drop in voltage the amps will
increase to keep the watts constant causing heat amps cause heat...
a booster transformer will raise the voltage back up so the device will draw less amps and run cooler, i wish i could explain it better but
then i would confuse myself jim

Ever wonder why most mexicans have a couple or more dead fridges or washing machines in their yard? Because of these low voltage problems, the motors
just burn out. I burned out a couple computers too...ugh. How much $$$ is one of those gismos you're talkin about???? HELP

That is what i was thinking of but it was in the 70's since th i bought one , maybe that price is because of the ground fault stuff in them
,do they have ground fault ckts in mexico ? i will check some whole sale houses in so cal see what they got jim

In San Felipe the voltage is often above 130 acording to a firend who retired here and worked for PGE in his former life.

Larry when i lived in san bernardino ca edision would feed 8 to nouses off the same transformer and we got @108 volts took a lot of b-tching to
get more transformers set
shari the post that al g sent check out that site that is what i was trying to describe i had no idea that they were so pricey think i only
bought 1 or 2 and i was using my bosses money jim

I think I am lucky running off an inverter in a solar set up. My voltage is always around 100 to 103. Only things I have stacked up in my yard, in
San Felipe, is motion lights. They don't like low voltage. Oh yea, and one 12 year old tv. I put 7 years on it on my inverter and 4 years before
that in the old country. Fortunately I have a lap top and they run off a 110 brick which drops the voltage.

All right all you "Electricity Gurus"....Can anyone tell me if this is why ALL my electric clocks....clock radio, stove, microwave & coffee-maker
clocks all gain about 30 minutes a month & all at the exact same rate? Is there a single device that could be installed between the source &
the usage to protect everything on the entire system? Voltage regulator SOUNDS like the right kind of thing, but would that compensate for drops, as
well as spikes? So far, all I've had burn out was a surge protector for my PC! Which is not a good sign! Never knowing what time it really is,
unless I'm at my PC or think to put my watch on, is aggravating, but the thought of potentially burning out an entire casa of new appliances is very
sobering! Any suggestions for new construction to do things right from the beginning & hopefully prevent potential headaches & cost down the
road?

My opinion on fast clocks in the La Paz area is, instead of maintaing 60 cycles they run maybe 61 cycles.

The WHYS & WHEREFORES are beyond my comprehension....but is there a realistically affordable work-around to protect appliances & could it be
incorporated into new construction would be easier for me to wrap my mind around? I think....if it's a relatively straight forward yes/no answer! I
need an answer geared toward an electrical novice!

CLOCKS
Most home wall clocks are controlled by the cycles, not the voltage. So if the cycles are maintained at 60 Hz, the clock keeps good time. If the
cycles go up or down, the clock runs faster or slower. More expensive clocks have compensating circuits that correct the error. Or buy battery
powered clocks, they are cheap and will run for about 6 months to a year on one AAA battery.
Cycles are not affected by voltage line loss or your neighbor welding his Baja Buggy. The thing that pulls cycles down is large inductive or
capacitive loads. so unless your neighbor is a large manufacturing plant or oil refinery, any cycles problem is being caused at the source. The gen
set isn't running at a constant speed or that speed is too high or low.
GROUND FAULT PROTECTION
Ground fault protection relies on a good grounding system. That means you need a 3 wire system and 3 prong receptacles that are connected to ground
correctly, plus the neutral also has to be grounded correctly. Trying to run ground fault circuits without that 3rd wire will cause constant trips.
Most house wiring in Mexico I've seen are two prong. When I use my Autoformer on my RV, I normally have to run a separate ground wire to the water
faucet (if it's not PVC pipe).
MOTOR PROTECTION
An Autoformer that cuts off when the voltage exceeds it's correction capablilty is your best bet. The second (and more expensive) solution is to
install some kind of motor/generator or solid state power correction device. The third choice is to get off the grid completely, and go for your own
soler/gen set system.

yes but i don't think you can afford one do a search for auto transformers and volt age regulator nothing can be done for your
clocks in fact my self winding watch keeps stoping jim

A quality electrical contractor I know sez: You might build in one of the smaller voltage regulators (transformer is included). Ideal casa wiring
would put appliances with motors on one circuit if possible, and run only that circuit through the voltage regulator.
This allows for the smallest possible regulator which is less expensive. It also means lower operating costs as the regulator requires some power of
it's own, even when it's not being used.
The cost can be further minimized by sizing the regulator to feed only the refrigerator and the largest other load, and then only operate one
appliance at a time (in addition to refrig).

Lencho syncronous speed = 120xfrequency/poles of motor
120x60=7200/ 2=3600
so the speed can only be changed by the frequency which is controlled by the power co
also the zero reading from hot to ground is wrong most gov blds are ground faulted and if a meter is put across them , the ground fault will
trip
disclaimer that formula came from a navy electricians school in 1955 and my memory is pretty much shot jim

That'll certainly affect the phase, but I'm puzzled as to how that would affect the speed of a syncronous motor on the same line. How's that work?

My bad, I've been retired too long  You're right, the inductive and capacitive
loads will shift the power factor, but have no effect on the cycles.
