It could be a problem because if it's a 3-phase system it might be an exceptionally powerful water heater. See an electrician who will know what questions to ask once he has seen the probem.
3 phase system has more power than a single phase system
For a given load, a three-phase system requires around 75% of the volume of copper required by a corresponding single-phase system and, so, is more economical. A three-phase supply also delivers power more or less continuously, whereas a single-phase supply delivers power in pulses. Finally, three-phase motors are self-starting and physically smaller than single-phase machines of the same power rating.
There are several advantages of 3-phase power over single phase power. First, with 3-phase power, more power can be transferred with the same amount of wire (meaning the amount of copper used in all of the conductors transferring that power) as with single or 2-phase power. Also, power is transferred more "evenly" with 3-phase power because the "next peak" is closer than it is with single and 2-phase power. The 3-phase motors run more smoothly than those run on fewer phases. Also, there are motor design considerations (one being control of the direction of rotation) regarding the motor that make 3-phase power more attractive. Use the link to the Wikipedia article on 3-phase power and skim it. It isn't long and it is quite readable.
You cannot obtain a three-phase supply from a single-phase system without using some sort of rotary converter.
This is a rubbish questionTwo single phase transformers can be combined together to make a three phase system. It does not become a two phase system. Look up information of an open delta wired distribution system to see how they are tied together.See related links below.
A 3 phase system needs only to use 3 or 4 conductors, as against 6 conductors if it were 3, single phase conductors The amount of copper used in a 3 phase is much less than what would be needed in a single phase system carrying the same current, this reduction in copper allows for weight reduction and cost savings. The power losses in a 3 phase system are much less than in a single phase system.
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
In Europe they have both single phase and three phase.
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
Houses generally run on single phase power. It would not make sense to convert single phase to three phase to run a house. Please restate the question.
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
Use VFD to make 3 phase from single phase source.
