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.
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.
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.
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
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.
It is a systematic approach to integrated product design or product that emphasizes the response to the customer expectations and the combination of uniqueness and engineering. Concurrent Design mainly focuses mainly on the early phases of the project or product. Its central concept is the use of collocated sessions during which the team shares and discusses all design aspects in a structured way, usually in the presence of the customer.
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 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
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.
When a black hole collides with a white hole, it is theorized that they would cancel each other out, resulting in the release of energy and potentially creating a new type of cosmic event.
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.
the force or other moving object
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.
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.

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.
sun releases solar flare, because many hydrogen collides on each other.
It rotates. For planets and other large bodies in our solar system it causes day and night phases as points on the surface come into the light then back into the shadow.
