There are two basic three-phase configurations: wye (Y) and delta (Δ). As shown in the diagram, a delta configuration requires only three wires for transmission but a wye (star) configuration may have a fourth wire. The fourth wire, if present, is provided as a neutral and is normally grounded. The three-wire and four-wire designations do not count the ground wire present above many transmission lin… WebA 'High Line' is one built on an elevated grade or trestlework/viaduct, like the PRR low-grade bypass line "behind" 30th St. Station that facilitated freight west from Morrisville.
