short circuite means phase to phase,three phase short, phase to earth, three phase to earth, this is all short circuite
6350.8 volts AC rms. The phase to earth voltage is ( square root(3) ) x lower than the phase-phase voltage on a 3 phase system.
There is such a thing as a three phase to earth fault, so maybe this is what you mean by a "balanced earth fault". I don't believe any earth or ground currents would flow in this case. A restricted earth fault is a typical phase to earth fault, where the zone of protection is restricted to a specific area, such as around a transformer. "Restricted" is referring to the protection method, not what is actually going on with the currents and voltages.
These relay sense the Negative Sequence Voltage components of system supply & offers protection against Phase Failure, Phase Sequence Reversal with Under/Over Voltage conditions which are dangerous to motor winding and cause motor burnouts.
it causes over modulation .... that is the phase reversal of carrier signal ..... the modulated wave then exhibits envelope distortion which results in loss of data .....

what does visa reversal mean
I understand that when generating energy 3 Phases energy it is purposely generated at 90º phase lag. If one of the phases fails to lag and catches the other in frequency, the phases become same as one.

As stated in Wikipedia: "The last reversal was theBrunhes-Matuyama reversal approximately 780,000 years ago."
Single phasing preventor is an electronic circuit which prevents the Thee phase operated Electrical machines from single phase cut off, Phase reversal and phase imbalance.
No. The reversal of polarity is a reversal of Earth's magnetic poles. The Corilolis effect is a direct consequence of Earth's rotation and is not affected by the magnetic field.
The process by which Earth's magnetic poles change places is known as geomagnetic reversal. This occurs when the Earth's magnetic field weakens, causing the north and south magnetic poles to switch positions. This reversal can take thousands of years to complete.
You can't have a three phase earth fault, you can have a phase to phase or a phase to earth fault. If you want the potential phase to earth fault current it will be your voltage times your impedance. If you want the phase to phase potential fault current then you should just double the above result.

Type your answer here... divide
A magnetic reversal is when the Earth's magnetic field changes direction, which has happened multiple times in the planet's history.
