The generated angle between phases in a three phase system is 120 degrees.
why three phase induction motor is delta connected
With a purely resistive load the phase angle will be zero. A 'star system' refers to a three phase power system with a resistive load placed between each phase and the neutral. If you have a resistive load(s*) evenly balanced across all three phases the phase angle will be zero, although depending on which point you look at, the current will actually be zero. The 'star system' is to help compensate for unbalanced loads. In practice you are going to have a lot of inherant inductance in such a system. So either the load will have some capacitance built into it to compensate or you will have a special reactive power compensator unit to deal with it. *Actually this will be three loads.
A symmetrical fault is a fault where all three phases are experiencing the same thing. This is also called a three phase fault, since all three phases are involved.
Release from source, dispersion and deposition.
In order for something to be shocked it must have a path to ground. If the bird is setting on a power line it is not grounded so therefore it does not get shocked. If the crow were to spread its wings to fly and get between two phases then it would be shocked because it would basically become a buss bar between two of the three phases.
Cities grew, at least between the period of dispersed protoindustrialisation and that of industrial decline. But what three phases of industrialisation are they? It's a bit like asking what are the three phases of a hairbrush.

Bond Angle
The three phases of transferring gases between the environment and the cells: Breathing, the transport of gases and the exchange of gases. (Came straight from my biology textbook)
Physical phases of matter are not limited to three. Phases of the moon are not limited to three. Phases of a wave form are not limited to three. What phase is limited to three?
There are three phases of drug effects. These three phases are the administration phase, active phase, and the metabolism phase.
Its development can be divided into three phases
explement of the angle or conjugate of an angle
A 63o angle would be narrower than a 90o angle (right angle), and wider than a 45o angle (halfway between a right angle and no angle), placed almost exactly between these two angles.
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.
Both third angle and first angle projection display the standard three orthographic views of a part or assembly on a drawing.. The key difference between third angle and first angle is the layout of the part on the sheet.
