2. Mathematics of three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Mathematics_of_three-phase...

   An important property of three-phase power is that the instantaneous power available to a resistive load, = =, is constant at all times.Indeed, let = = To simplify the mathematics, we define a nondimensionalized power for intermediate calculations, =

3. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   An important class of three-phase load is the electric motor. A three-phase induction motor has a simple design, inherently high starting torque and high efficiency. Such motors are applied in industry for many applications. A three-phase motor is more compact and less costly than a single-phase motor of the same voltage class and rating, and ...

4. Symmetrical components - Wikipedia

   en.wikipedia.org/wiki/Symmetrical_components

   Symmetrical components are most commonly used for analysis of three-phase electrical power systems. The voltage or current of a three-phase system at some point can be indicated by three phasors, called the three components of the voltage or the current. This article discusses voltage; however, the same considerations also apply to current.

5. High-leg delta - Wikipedia

   en.wikipedia.org/wiki/High-leg_delta

   Center-tapped delta transformer Center-tapped delta transformer voltages. High-leg delta service is supplied in one of two ways. One is by a three-phase transformer (or three single-phase transformers), having four wires coming out of the secondary, the three phases, plus a neutral connected as a center-tap on one of the windings.

6. Polyphase system - Wikipedia

   en.wikipedia.org/wiki/Polyphase_system

   One voltage cycle of a three-phase system. A polyphase system (the term coined by Silvanus Thompson) is a means of distributing alternating-current (AC) electrical power that utilizes more than one AC phase, which refers to the phase offset value (in degrees) between AC in multiple conducting wires; phases may also refer to the corresponding terminals and conductors, as in color codes.

7. Power-flow study - Wikipedia

   en.wikipedia.org/wiki/Power-flow_study

   In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as voltages, voltage angles, real power and reactive power.

   The Hoosiers moved up three spots to No. 5, but they still aren't being completely appreciated by the committee. Indiana is still one spot behind Penn State, which doesn't make all that much sense.

9. Scott-T transformer - Wikipedia

   en.wikipedia.org/wiki/Scott-T_transformer

   A Scott-T transformer or Scott connection is a type of circuit used to produce two-phase electric power (2 φ, 90 degree phase rotation) [1] from a three-phase (3 φ, 120 degree phase rotation) source, or vice versa. The Scott connection evenly distributes a balanced load between the phases of the source.
