Single Phase Transformer Primary and Secondary wiring.Re: delta-connected system Is this a corner grounded system with 240v between legs and no 120v loads? If so the grounded leg should be white. (2 hot phases and one grounded phase) Your equipment could look like single phase stuff. Two pole breakers. If you do have 120v loads on the service it is center tapped delta and there is a high leg.The high-resistance grounding (HRG) method for electrical power systems has some of the same advantages as ungrounded systems. These advantages include the reduction of equipment damage (due to the low value of the ground-fault current), and no need for immediate removal of the first ground-fault, with the additional benefit of achieving acceptable values of transient overvoltages.Voltages are a-b 240v, b-c 240v, c-a 240v; on center transformer x1-x2 120v, x2-x3 120v; x2 to wild leg 240v ... The name simply comes from drawing a schematic of a delta with a ground symbol on one corner of the drawing hence the name corner grounded instead of the midpoint ground found on the schematic of a combination power/lighting drawing ...(if the same genset was wired wye, it would be 415V between phases, 240V phase to neutral) Wyes always have neutral in the middle. Deltas are stranger as there is no natural place t connect a balanced neutral, so you get oddities like wild leg delta or corner grounded delta.This makes ØC the System's Grounded Conductor. Color Code for this Conductor = White. Voltages are as follows: A-B: 240 VAC, A-C: 240 VAC, B-C: 240 VAC, A-G: 240 VAC, B-G: 240 VAC, C-G: 0 VAC. ("G" = Ground / Equipment Grounding Conductor / Grounded Conductor). Now to the 2nd question: Quote Or does anyone know of any sites that give schematics??The following drawings describe a 3 Phase 3 Wire Corner Grounded Delta. Transformer connection, and the nominal Voltages at various points. Drawings included are for 240V, 480V and 600V 3 Wire Deltas. Figure 1a: Schematic drawing of the 240VAC. 3 Phase 3 Wire Corner Grounded Delta. Figure 1b: Layout drawing of the 240VAC.Jun 09, 2004 · | 240v Highleg delta is A phase 120v to ground, B phase is 240v to ground and C phase is | 120v to ground. All phase to phase voltage is 240v. I have never seen or heard of 240v | Wye system here is the U.S. But to answer your question the buss bars will handle | voltage above 120v. I disagree with you on the B phase. Draw the triangle with 240 ... The phase to ground voltage on a 480 volt ungrounded delta system is 480V. NEC 250.97 applies. The voltage to ground for ungrounded circuits is the greatest voltage between the given conductor and any other conductor of the circuit. For a 3-phase, 3-wire ungrounded 480-volt system the voltage to ground is 480-volts.snell motorsHigh-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a three phase transformer (or transformer bank).GU5.3 // 220-240V / 50-60Hz // TE ... (ground) by an earth conductor. ... My Delta Light members get unlimited access to all downloads. Recent Projects You are correct that most 240V services are grounded. As for fusing one leg, grounding the other leg of three single secondaries is no less safe than having a 480Y/277V 3-phase 4-wire system. If the primaries are connected to "rotated" phases (i.e. AB, BC, CA), you will have essentially a 416Y/240V 3-phase 4-wire secondary.I Line =150,000VA÷ (240V×1.732)= 360A. Fig. 3. When solving for phase current, don't forget to divide the overall transformer kVA rating by 3. You can calculate the phase current of a delta transformer winding by dividing the phase VA by the phase volts: I Phase = VA Phase ÷E Phase.This could be a 120v, 240, or 480v delta service. My recommendation, as always, is against using a self-contained meter for voltages above 240v however. In the center of this diagram following the blue wire again this is an either or connection. You can connect the wire to the left center terminal or the bottom center terminal.480 To 120/240 Transformer Wiring. a volt primary transformer with a volt secondary is operated at volts, regardless of whether the source is three phase 3-wire or three phase 4-wire. .. example: A 10 kVA transformer, / volt secondary is to service an 8 kVA .
