SUMMARY

The discussion clarifies the concept of line-to-line voltage in a wye-connected system, specifically noting that in this configuration, the line-to-line voltage is 5KV at the load. It distinguishes between real power (measured in KW) and reactive power (measured in KVAR), explaining that KW represents usable power while KVAR indicates power stored in inductance or capacitance. The neutral point in a wye connection serves as a reference, with line-to-line voltage referring to the voltage between phases rather than between a phase and neutral.

PREREQUISITES
  • Understanding of three-phase power systems
  • Knowledge of wye (Y) and delta (Δ) configurations
  • Familiarity with real power (KW) and reactive power (KVAR) concepts
  • Basic electrical engineering principles
NEXT STEPS
  • Study the relationship between line-to-line and line-to-neutral voltages in wye configurations
  • Learn about power factor and its impact on real and reactive power
  • Explore the implications of reactive power in electrical systems
  • Investigate the calculations for three-phase power in wye-connected loads
USEFUL FOR

Electrical engineers, students studying power systems, and professionals involved in the design and analysis of three-phase electrical networks will benefit from this discussion.

Homework Statement



The 3Phase loads are connected in parallel.
L1(Purely Resistive) consumes 300KW. Connected in wye!
L2(Purely Inductive) consumes 300KVAR. Connected in wye!
L3(Purely Capacitive) consumes 300KVAR. Connected in wye!

The part I don't understand is the following: LiNE to LiNE Voltage is 5KV at the Load.
My question is brief. I am trying to find out what does it mean by line to line voltage, in a wye connected

Also why are the units of consumption of the different loads different. I mean KW and KVAR's, or are they not different?

Thank you for the time applied to this question.

KW (kilo-watts) is Real Power as opposed to KVARS (kilo-voltamperes-reactive). The reactive power is power that is stored in the capacitance or inductance of a system, and is unavailable for use.

In a Y, the central point of the Y would be neutral, and line-to-line means the volage/current between phases, as opposed to line-to-neutral.
 
Thank you!

Thank you for the help. I actually got everything done just those little details that I tried to find yesterday desperately. Thanks again.
