Floating wye
Webfloating wye, open delta). It can also occur for the grounded-wye-wye connection, when the transformer is on a four or five-leg three-phase core. These core configurations are … WebMar 31, 2024 · FLOATING GROUND 480 VAC. Line 1 to ground is 500vac, Line 2 to ground is 480vac and Line 3 to ground is 30vac. Why or how does this happen, my supervisor mentioned something about "floating ground in the facility". To make it more fun it is possible that the voltages will change depending on what machinery is operating.

WebOct 2, 2013 · In a wye connected HRG system, intermittent faults that cause so much trouble in ungrounded systems will be eliminated by the neutral system ground resistor because its insertion limits the total current flow to ground. System continuity is maintained because, although ground fault alarms occur, the overcurrent devices do not operate. WebJul 5, 2016 · 1 Answer. 1) This is a typical delta to wye configuration. I might add that normally these 3 transformers would be built as one chunk of steel with 3 sections, one for each phase. The floating Vn wire is just to show that the primary is delta only, neutral is not used. 2) Because this is 3-phase the difference in phases is 120 degrees.

WebJul 23, 2024 · The only way to get 120/240v from a 240v delta transformer bank is with one center-tapped secondary to derive a neutral; you'd have 208v to neutral from the high leg. Forgetting the neutral (which is normally grounded) for the moment, the voltages to ground on a floating system are meaningless. What you should have is a 240v delta (no 120v). O. WebMar 25, 2024 · The wye–delta transformer shown in Figure 9 is sometimes used to provide a neutral on a three-wire system but also can serve load from its secondary. Figure 9 – Wye–Delta Transformer. The primary wye windings are typically grounded. If the secondary is a four-wire delta, the fourth wire originating at a center tap on one of the …
WebJun 25, 2010 · The delta winding creates a short circuit for the 3rd harmonic and it is consumed in the delta winding. If there is no delta in a three phase transformer, such as Wye-Wye winding, a secondary current must induce a primary current. If the primary current has not current path, secondary current will not flow into the secondary winging.
