What will happen if two phases collides each other in three phase four wire system?

Generally if two phases are overlapped high voltage appears across the load . . . Before tht the generally a three phase 4 wire exists at outgoing of transformer hence at house hold applications the service mains trips . . .
AnswerI think you mean. 'What happens when two line conductors touch each other?' The answer is that there will be a short-circuit, which will cause the protection system to disconnect the circuit.

What does 380 volts between phases mean?
You cannot have 380 V between 'phases'. You can, on the other hand, have 380 V 'between lines'! '380 V between lines' refers to the voltage measured between any pair of line conductors in a three-phase system.
What is a 208 circuit?
The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases. 208 circuit would consist of two phases of a 208 volt wye system or could be all three phases. The voltage between conductors would be 208 volts. The voltage to ground from any phase would be 120 volts. A 240 volt delta system would give you a high leg to ground, somewhere around 190 volts and the other two would be 120 volts to ground.
How the Neutral displacement occures?
In a three phase connected system, if the loads are not balanced or if one voltage is disconnected due to any reason there will be neutral displacement to a new voltage level (from normal zero voltage). This can increase/decrease voltage in other phases
What does the phases on a nameplate of a motor mean?
On a three phase motor, the phases give you direction for how to hook the motor up to make it spin one direction vs. the other. If you hook up such a motor blindly with all three phases, it may spin in the opposite direction you want; to fix, you swap any two of the three phase connections.
If you are measuring the voltage of a three phase power system you take only two phase in account then why there is a need for third phase?
Answer Take all phases into account. Voltage is measured between two phases of the three phases at one time, so what this means is this...first you read voltage between line 1 and line 2...then you read voltage between line 2 and line 3...and then from line 1 to line 3. Each phase of a 3 phase system is 120 degrees from the other in a 360 degree pattern. It takes all 3 phases to start a 3 phase motor but can run on two. If a 3 phase motor tries to start on two phases it is refered to as single phasing and can damage the motor.Another AnswerFirst of all, let's get the terminology correct. The wires that join a three-phase load to its supply are called 'LINE conductors', not 'phase conductors'! This is very important. Phases, which are normally inaccessible, are either the generator windings, the transformer windings, or the individual loads, connected to the line conductors -this can make measuring phase voltages very difficult unless you can access the interior of these machines/loads.The voltage of a three-phase system is normally defined in terms of its line voltage, not its phase voltage, so one normally measures its line voltage by connecting a voltmeter between any two line conductors or terminals. As the line voltages are determined by the supply system, all line voltages should be the same, regardless of which line conductors you choose to place the voltmeter between.The important thing, however, and this is something your voltmeter will NOT tell you, is that the three line voltages are out of phase with each other -each lagging its predecessor by 120 electrical degrees. And this is important, because it is the phase displacement between these voltages, not the magnitude of each voltage, that allows -for example- a three-phase motor to self-start.
What collides with plate boudaries?
Other plates.
What will happen if a car collides with another?
it depends which one has more mass. if they are the same, i think they bounce off each other, but if they are different the the bigger one crushes the smaller one and stuff
What is comp and collision auto insurance?
Collision is meant to cover your car when it collides with something else. Comprehensive is also sometimes called other than collision, so it usually covers the other things that can happen such as fire or theft.
What can happen if one car driving North on green light while other car making left turn says he had the greelight and collide?
what can happen if car driving north on green going straightwhile other car making left claim that he had the green light to turn left and collides
What cased Japan's earthquake?
This is because Earth's plates collides together, rubs or go onto each other causing Earthquakes to happen. Please do not misunderstand this as the Pacific Ring of Fire as Japan is located in Asia continent, not in the Pacific area.
What is the slab of the earths crust that regularly moves away from or collides with other slabs called?
A tectonic plate.
What determines the change in direction of an object after it collides with another moving object?
the force or other moving object
What is ferroresonance?
We give the name ferroresonance to a type of overvoltage situation in 3-phase power systems that can occur when one of the phases in a loaded system opens. This puts a lot of "stress" on the other two phases, and in a system with a lot of distributed inductive and capacitive components, this is bad news. Overvoltage can break down insulation or simply "punch through" causing an arc. In either case, damage will occur. When a phase in interrupted, the other phases need to kick out, too, so that all phases of the circuit are unloaded at the same time. This will prevent the condition. Ganged breakers will do thid, that it, they'll kick out all phases at once. And sensors are placed on each of the phases so differential loads, when great enough, will trip the breakers and cause them to open. A link follows.
How do the phases of Venus's help?
Galileo was able to observe Venus going through a full set of phases, something prohibited by the Ptolemaic system (which would never allow Venus to be fully lit from the perspective of the Earth or more than semi-circular). This observation essentially ruled out the Ptolemaic system, and was compatible only with the Copernican system and the Tychonic system and other geoheliocentric models such as the Capellan and Riccioli's extended Capellan model.
Do the planets wax and wane in the night sky?
Mercury and Venus do, becoming crescents as they pass near us, between us and the Sun. The other planets do not show significant phases. The phases of Venus were important in the development of the theory of the Solar System, because after they were discovered by Galileo, people realised that the gibbous phase could not be explained by the ancient Ptolemaic system.
What does 380 volts between phases mean?
You cannot have 380 V between 'phases'. You can, on the other hand, have 380 V 'between lines'! '380 V between lines' refers to the voltage measured between any pair of line conductors in a three-phase system.
Why the sun send out solar flares?
sun releases solar flare, because many hydrogen collides on each other.
