Can a reversed power flow through the primary core of a CT result in a incorrect metering readings?

The CT will only work on an AC circuit so I don't see where it would make any difference.  The only thing that would is to have another phase too close and the magnetic fields might cancel each other. Since the current being measured is AC the output from the CT will also be AC and shouldn't matter on the leads.

It takes energy to push that current through your lights and appliances, and that's what your paying for. One way to see it is to consider that what comes out the downstream prong is at 0 volts and therefore of no use to anyone. Or, you could just wire all your lamps in series and see how that works!

Stray voltages/currents between grounded metal parts is caused by a difference in resistivity. Usually, it is because the ground rod has a greater resistivity than the metal parts connected to the water/drainage/gas system.\nAgain as has been said on other occasions in this forum, Ohm's Law comes into play..... Current is equal to voltage divided by resistance. So if there is a differing resistance between the two systems AND there is a low resistance path betweeen the electrical wiring and earth on an appliance, current will flow (continuously) to the frame of the appliance and to ground. So if current is flowing to ground and the appliance ground has a higher resistance to earth than the ground of the adjacent metal parts there will be a difference in potential between the two. This is often felt as a tingling sensation --- The reason why it doesn't trip the breaker is that the current flow is lower than the trip setting of the ELCB (earth leakage circuit breaker). It does not have anything to do with "Back EMF" back EMF is the voltage generated in a dc motor that limits the amount of current that can pass through the armature windings.......\n\nIf you have this problem, GET AN AUTHORIZED ELECTRICIAN TO INVESTIGATE AND CORRECT THE PROBLEM IMMEDIATELY. It certainly is a dangerous situation that can cause death.\n\nSource: Electrical Engineer (ret) with 45+ yrs experience.

For computer to do it, I would have been thinking a short in the PC's power supply, for two, no way. I am guessing your computers are connect via the same point of double adapter somewhere and have a suspision that there is a break in the Earth within the cables or adapter somewhere.\n\nThis means the chasis of your computer will not discharge and slowly creap up to high voltages over time, even though the PC's are not on.

Possibly "statistical fluctuations in charge generation" as mentioned in ref. 1. From ref. 2, which refers to "fundamental limits imposed by charge generation statistics", I get the impression that these variations may be an irreducible error source.

The meter must measure the power you use (and must pay for) using the formula P = IE (power equals current (I) times voltage (E)).  To do so it must accurately dedect the line voltage and electrical current entering your house.  The meter contains an aluminum disk that you can see spinning fast or slow depending upon how many (or few) electrical devices you have turned on.  Inside the meter there are two coils of wire (one on top and one on the bottom of the disk).  One coil senses instaneous voltage that can vary (and even droop in a brownout).  The other coil detects all the current you are using, if any.  With your main circuit breaker open there will be none.  When there is both voltage and current flowing, magnetic eddies are produced that measure and integrate the power being used by spinning the aluminum disk (like a small motor) which is connected to a set of gears that turn the meter numerals.  See the link for an illustration and detailed explanation.  Good luck.

As I said in my answer to your other question, be sure you are making a firm connection.  By how much is the reading changing?  If it's a digital meter, each reading is a separate measurement, and any series of measurements will show at least some differences.

try\nhttp://www.dir.ca.gov/title8/2395_42.html\nsection b\n\nGrounds are also tied to the cold water pipes and gas pipes.\nmake sure all circuits are dry and checked with a insulation resistor tester (megger).Readings above 2 Mega Ohms should be OK.

consider a charged capacitor.most of the electrical circuits are grounded.i=c(dv/dt){hope u know the notations). so as long as a potential(voltage) difference exists, a reverse current is formed and flows through the capacitor, at the same time using up the energy stored in the capacitor.in most electrical circuits, the lower potential id the ground potential.even if the capa. is not grounded, it can discharge as long as it is connected to a lower potential(voltage) than itself.

If you had power issues then lagging would be the least of your problems. A switching power supply will shut down if overloaded. If you are concerned that your PC may be getting close to pushing the limits of the power supply, You can check the the amperage either on the AC or DC side with a clamp-on amp meter to determine the load the PC is drawing.

Check your power-supply fan.

Although it is quite possible that nothing noticeable will happen (I have done this hundreds of times without major consequences), you should try to avoid it at all cost. There are three main reasons for this:\n\n1. You will probably lose any unsaved data.\n\n2. It could damage your computer and/or shorten its life.\n\n3. It could cause some files (that HAVE been saved) to be permanently deleted and/or corrupted. Although this is fairly rare, it has happened to me before--and the possible risk is worth serious consideration. All files are at risk; including system files, program files, and all personal files.\n\nSo I suggest that you fix this problem. There are a few different ways you can do this. Your best option is to buy a battery backup system--it should cost you about $25-$45--it will protect your computer from unexpected blackouts as well as it being accidentally unplugged. You could try getting a new surge protector (I assume that is what you mean by an "extention thingy that has a saftey on it")--they are usually about $5, but you can sometimes find them for free with a rebate. However, if you aren't going to get a battery backup, instead of replacing a functional surge protector, I suggest you simply bend the electrical contacts (prongs) outward slightly; this will improve the electrical connection and hold the plug in place.

swap wires,see if wire to blame,then plugs

A ct system doesn't generate enough radiation to change the water.  And yes, it is safe to drink.  I would make kool-aid, set up a stand and safely sell it to neighborhood school children!

This is what I found for you on www.qtsaver.com:\nVoltage harmonic distortion is distortion caused by harmonic currents flowing through the system impedance.

What's to know?\n\nIt's the typical offset voltage, or DC component of the output.  The signal is AC.

yes you can. For real low freq. you can actually do a DC measurement. Just slow the sweep rate way down and you will see it.
