What is the symbol of phase sequence?
The symbol of phase sequence is RYB
What is the difference between positive sequence and negative sequence arrangement?
The order in which the voltage of the coil reaches to the maximum value is called the Phase Sequence.POSITIVE PHASE SEQUENCE: If the coil is rotated in anticlockwise direction, the phase sequence will be Positive Phase Sequence, i.e., R-Y-B or A-B-C.NEGATIVE PHASE SEQUENCE: If the coil is rotated in clockwise direction, the phase sequence is called Negative Phase Sequence, i.e., R-B-Y or A-C-B.NOTE: Phase Sequence is of great importance in parallel operation of three phase transformers and alternators.
This process consists of evaporating a liquid then condensing it again?
This process is called "distillation" and can be used to separate chemicals or other compounds that have different boiling points. This is used to obtain alcohol from fermented grain, and to extract various components such as gasoline from petroleum.
What phase change used in distillation?
Boiling and condensation.
How Negative phase sequence relay work?
How Negative phase sequence relay work
How does sublimation compare with other changes of state?
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
In a refrigerator which two phase changes must occur in order to keep the food cold?
Gas to liquid, liquid to vapor
Why is the period of the embryo regarded as the most dramatic prenatal phase?
It is considered as the most dramatic prenatal phase as lots of changes occur in this stage and it is also the most hazardous of the three prenatal stages because most miscarriages occur at this time
Sequence of phases in the cell cycle?
Interphase## G1SG2ProphasePrometaphaseMetaphaseAnaphaseTelophaseMitosisCytokinesis
Why to knw phase sequence?
If you reinstall a three-phase motor with two of the supply conductors interchanged, then the resulting negative phase sequence will cause the motor to run in reverse.
How do you do for phase sequence protection at three phase motor operation?
motor is designed to operate in forward and reverse direction for the purpose of elevator. Phase sequence protection is not required.
Why phase changes are reversible'?
Phase changes are accompanied with optical contrast and therefore the feasibility of phase.
