What does the electrical term wye/delta mean?

Answer by  hbdrew14 (137)

They are theory terms used to describe how an electrical system derives the voltage on a given circuit by potential to other voltages.

Answer by  dbal (60)

The Y-Δ transform, also written Wye-delta is a mathematical technique for the analysis of an electrical network. It resembles the name of the circuit diagrams which looks like letter Y and Greek alphabet Δ(Delta). It is a transformer with Wye connected as primary and Delta connected as secondary. The Wye-delta transformation shows the equivalence of network with 3 terminals.

Wye/delta refers to the two different ways an electrical network with three terminals (common in power applications) can be represented mathematically.

Answer by  TitusMcCoy (44)

Wye/delta, also written Y-delta or Wye-delta, is a mathematical transformation that establishes equivalence for networks with three terminals. This technique simplifies analysis of an electrical network.

Wye-Delta is a mathematical equation formed into a technique. It is an analysis of an electrical network. It is named for the design of the circuit diagrams which look like the letter Y and the Greek alphabet Δ (Delta). The Wye is the primary connection and the Delta is the secondary connection.

It's how neutral relates to the power lines of 3 phase. Wye: each line feed is equal voltage from neutral. Delta: neutral has no direct relation to any phase.

It is refering to the type of electrical system you are using. It is the way the wires are rated per leg.
