whether we can use the same device which is operating at 3-phase in 2- phase connection?

You cannot do this directly. Assuming you are talking about a motor, It may be possible to get the motor to turn using a capacitor but you will not get the rated torque (turning force). I'm sure there is plenty 3 phase theory on the internet if you want to see why they are so different\n\nOne way it can be done is by using an inverter that takes single phase input (providing the voltage you require is not higher than the voltage you have or you will then need a transformer as well). The inverter gives you the added value of being able to vary the speed but it may be cheaper to simply buy a single phase motor. As you didn't actually specify the device to be motor, be aware that VSD inverters may not work on other equipment.\n\nYou need to be wary of the size of the device you are trying to operate. Often 3 phase is used for higher powered devices that becomes in-practical to try and run on single phase anyway.

I use a power inverter.

DO NOT do that!  It would be dangerous (creates a fire hazard), and one of the protective devices (fuse or circuit breaker) would probably trip under load regardless.

you can but you have to make sure they have the same pins,as i am sure that they don't have the same number through the p2 range

No, that's not a good idea - neutral may not be the same as ground (0 volts).\n\nThink of it this way - the neutral wire provides a return path for the electricity to get back to the power company.  The ground is there to act as a shield, to protect the device from radio interference (if it's an electronic device like a computer).  If there's a ground fault, and you connect neutral to ground, the device may still work OK, but there may start to be "flakey" intermittent failures, like bad signal or data loss, because the neutral voltage is sending interference signals throught the device ground, instead of being shielded by the ground.

In short yes.  I would not run them interchangeably.  They make frequency converters that you can place in-between those segments.  I saw one by Winncom a while back that was compatible with both ver. of coax

Here are some sites that may help.  Both have circuit examples utilizing LVDT's.  Hope this helps.

Usually not recommended, but sure you can as long as all are same type (PC2100/PC2700 or PC3200)

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.

If one of the three phases is lost, the current drawn by other two phases would rise and following consequences would follow:\n1. If motor was not fully loaded and current drawn by remaining two phases (after loss of one phase) of motor are less than its rated current, motor would continue to run.\n2. Motor would get heated and thermal over load should protect it.\n3. If phase failure or negative sequence or unbalance protection was provided motor would be stopped by activitation of these devices.\n4. If neither of above protection is provided and motor is loaded in such a way that it results in over heating, motor may burn if temperature rise is more than temperature which its insulation can withstand. There are different limits for different class of insulation.

probably the fact that it is made for the usa market and the power rateing is 0nly 120volt not 240 like ours,so if u get it and plug into the mains u will burn it out so u have wasted ur money,try european markets but stress u need for uk

The TXMR's must have the following to load share\n1 the same primary and secondary voltage windings\n2. of the same Phase relationship (vectors)\n3. have the same impedance %

Each should be marked with a Vector Group Reference.\nThis gives phase angle and lead or lag angles. \nThese should be matched before connecting them.\nAfter connection the load should be introduced to the board in synchronism with the supply.

I've found a good site introducing and explaining the voltage and phase relationships between delta and wye 3 phase transformers. Try www.elec-toolbox.com/usefulinfo/xfmr-3ph.htm\nI hope that this proves useful for your research.

Yes and no.  A 3 phase load is balanced, like a 3 phase motor, and doesn't even connect to the neutral, so there is no neutral current for that case.  Also, single phase loads that are connected from one phase to another will have no neutral current.  The neutral is the return current for single phase loads that are connected between a phase and neutral.  The NET neutral current will be the unbalanced current (if all the phases had the same current the neutral would be 0), and will be no more than the largest phase (ignoring harmonics).

yes it can in the three phase mode

You will need an adapter.\nhttp://en.wikipedia.org/wiki/List_of_countries_with_mains_power_plugs,_voltages_and_frequencies
