The blinks are affecting customers on other transformers?

Any weather correlation? I am also interested in what the distribution circuit looks like. If, as waross suggests, it is a long circuit there are distribution events that might explain it. For what it is worth the transformer itself wouldn't be high on my list of suspects. Just for clarity...

Sorry for the redundant questions, I should have refreshed before posting

Can you give more information? Duration of the blinks, common time of day, for example. Have you contacted the utility (or are you the utility?) Do you know anything about the utility source?

Capacitors are capable of building up charges through repeated switching w/o sufficient discharge time. If seen it referred to as "pumping". If your technician was switching frequently that is a possibility. The solution is don't do that. Wait a few (5) minutes between. Second when swiching...

Lots of good reasons to do it. Just start up headaches. Those are common.

Maybe read up on utility ratemaking and regulation. Then you wouldn't be asking these questions. But as a help to you, at high load times utilities use high fuel cost plants because they are cheapest to build and have short run times. Prices to consumers are fixed by the regulator. Simple...

Maybe read up on utility ratemaking and regulation

epepito, I am not worried about theft of my energy (or anything else, and I didn't mean to sound negative). I was simply trying be point out that some means of compensation would be necessary. The point I was making is that fact that the regulation function should mean close to zero long term...

epepito, I understand that the intention of the regulation would be to even out, never the less there is the real possibility that I would want to drive home immediately after a drain period and I would have to be compensated for any net drain. So all the payment issues would remain. Also the...

Also I agree with those who say buy an inverter.

In order for the idea to work on a large scale, lots of things have to happen that haven't yet. Who gets paid for the electricity we extract from the battery? How do we pay you? The building owner, who provides the plug-in point can't because he would be selling electricity the car owner...

Every business must pass all costs to the customer. Failure to do so means they won't make a profit and therefor will go out of business. If all the costs added up become excessive the business can't compete and also goes out of business. Utilities are rightly regulated. We have limits on how...

I have never seen a loss charge broken out. I think it is a good idea though. Customers pay for the full cost of doing business anyway (that is the regulatory compact) and more transparency is a good thing.

I think DPC is correct. If one is not licensed in a state and then stamps with another state's stamp he is essentially practicing or representing himself as a licensed Engineer in a state where he is not. In the original question, I think the supervising Civil Engineer could stamp if the work...

I like waross' explanation. I'll add; The load on each of the two leads in 120v rms with respect to the neutral. It is 240 v rms across both together. So when L1 is high, L2 must be low. So the current will flow from L1 to L2. The load on L1 sees it as the positive 1/2 cycle L2 sees it as the...

Thanks Herivelto, It is good to be reminded from time to time. I often misuse it and say VAR or KVAR when working with non-Engineers, so they know it is not a misspelling and it can become a habit. Dave

VARs happen naturally. Inductive loads, like motors, light ballasts and others draw VARs. Also most power delivery lines are inductive and draw VARs to deliver power. These VARs are "lagging" VARs. It is necessary and cost efficient to compensate for those lagging VARS with leading VARs that...

The calculation you suggest doesn't take into account the efficiency of the motor. You should divide by that as well. It should be something like .85 more or less. I agree that there are many other things to think about with a motor that size.
