bad power

[skystormfarms]

i have bad bad bad power in my apartment midday 100v 29.24hz midnight 142v 66.23hz 6pm 124v 60.22hz 6:33 am 144v 66.02hz
now what can this damage plz help cuse of this my will not run well in winter on this power

Re: bad power

You need a good UPS [Uninterruptable Power Supply] with a battery back-up.

Re: bad power

did that burnt up my triplite

Re: bad power

It could have if it wasn't a heavy duty model.
With power that bad you need a heavy duty model.
That's what I meant by 'good one'.

Re: bad power

I lived rural in Washington State for a few years.
I was right between two power plants but they were both far away.
The load shifting between the plants made my power nuts.
Even incandescent light bulbs only lasted 3 or 4 months if they were on a lot.
A good UPS was the only work around for the problem.
[I even had one to protect the stereo..]

Re: bad power

How did you measure the freq? Was this a 'soft' measurement by the UPS?

You'd have a blackout long before you ever truly had 30Hz - 66Hz.

Those voltages make me suspect an open neutral, anywhere from the POCO TXs and the building's service to the feeder for your apartment sub panel.

Did any other units experience voltage issues? Some bulb dimming when appliances and esp motors start may be on the edge of normal, depending on feeder sizes/imedances. But if you have bulbs that brighten as well as dim when your fridge or washer starts, do something about it before stuff gets fried.

Re: bad power

recording v and hz meter for a week if what you say is tru than its my zinsco pannel

Maybe where you are.
Where he is it depends on how the power grid is set up.
[And how good the control techs are. - Ever see generators paralleled out of phase?]
It's almost July and he's saying it's Winter there.

Re: bad power

no its spring we just have a cold spring

Is this you?

But Zinsco panel makes/made me think US.

I'm ASSuming the recording meter is connected to the lugs of the panel and not a branch bkr with possible corroded stabs.

I get USA and 5-15 receps from this thread:

As well as the no trip Zinsco.

yes
i am skystormfarms on youtube and badcaps how did you find that out

Re: bad power

One of your vids was 'suggested' or 'related' when I was looking at various electrical stuff on youtube one night.

The diagrams are for 120/240 1ph 3w service. Your apt building probably has 208Y/120 3ph 4w service, with 120/208Y 1ph 3w "network" service to your subpanel. Network service also used in metro areas with transformer vaults in front of buildings, such as NYC.

Not as likely, it may have a 240D/120 3ph 4w service, with the center tap of one transformer grounded. This will be the 'lighting' transformer, the other two being 'power' transformers.

With Ohm's Law in mind, study why what happens in the diagrams actually does.

Again, do other units have power problems, or just yours?

Bonez, paralleling w/o syncing, with enough of a phase shift may just as well be creating a short.

Re: bad power

well one or2 more things my apartment is fed by a poll t-former and i do smell burnt motor nere that pole

Re: bad power

But your apt is the only thing with voltage issues?

This came up in your 'ground fault' thread a while ago:

http://www.youtube.com/watch?v=uMV1jmDn3o4

One thing to watch is when the L-L voltage, 240V if you have a 1ph service w/ a 120/240 tx, slowly creeps up.

240V, then 244, maybe 248-252 or 258 after a while. Of course, these measurements must be checked at the same times of day or similar/repeatable loading conditions.

If the primary of the dist tx starts getting some shorted turns, this is one of the things that will happen. The turns ratio is reduced (increasing secondary voltage) and the shorted turns overheat.

Is there oil dripping from the transformer's bushings?

I know how it works bro.
Former power plant operator on ships.
Paralleling generators was an every day thing.
Very easy to hit 30Hz without actually dumping it.
It's called a brown-out.
It does tend to scram reactors though so us reactor operators were very attentive when the electricians were playing with the generators.

Re: bad power

no but thear is oil on the pole do you think that me being blown up may have to do with this

Re: bad power

Other way around.
It caused your damage.
