The open Delta or V-Connection transformer is an improvement of the 1 three-phase transformer. The open Delta transformer can restore power in a Delta-Delta three-phase bank when one of the three single-phase Transformers, which can be individually disconnected and replaced in case of failure, breaks down. The open Delta transformer then allows functionality to be restored, but at a reduced power of 57.7 of the original power.

∙ 11y agousually a 3 phase transformer is 3 separate single phase transformers
they are wound on 3 cores the return magnetic path shared with all three phases
the input and output leads generally come out separately an can be changed around
480 delta to 240 delta
could be reconnected as 480 delta to 416/240Y
pretty close to Europe's power
lots of transformers have taps to adjust output voltage
we have used this very thing to run some German machine tools here in the usa

What connection is the higher ampere between delta and wye?
For the same load, delta provides higher current than wye, or star.Wye voltage is 1 / 1.732, or 0.577 that of delta. (1.732 is the square root of 3.) This gives a power of 0.333 for wye, as opposed to delta. (0.5772 = 0.333)This is why (no pun intended) we use wye-delta starters on large motors - it allows them to come up to speed at 1/3 power, before switching to full power on delta.
What is wye-delta motor control?
It is a type of starter that allows a motor to be started across the line by starting the motor with a reduced inrush current. The motor is started in a wye configuration until it gets up to speed and then a timer drops the wye contactor out a draws the delta configured contactor in. The motor then operates in a delta wired configuration.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What are the problems associated with the y-y three-phase transformer connection?
Your third leg is called the high leg and can exceed 180 or more volts. In a 3 phase panel you will loose a third of your circuits unless they are used for motors or other equipment that uses three phase evenly through its function {meaning it doesn't use one leg exclusively for controls or 110V functions. It get a bit involved explaining the windings of a transformer and center taps but suffice it to say one leg gets more than it's share of windings in the transformer. It was used in the early years of industry when single phase 240V systems were the only game in town and they wanted to get more power from the Wye set up prior to delta. It never was popular but a necessity for industry and grew only because of slow development incorporating the 208V delta 3 phase system.
Can you use a 9volt 500 milliamp transformer for a door bell?
The key is the door bell specification. They typically run on a 24 VAC transformer. You can certainly hook it up and try it with 9 volts, but it probably won't work as intended. 24 Volt transformers are relatively cheap.
Is a step up transformer a Ynd or a Dyn?
Whether a transformer is 'step up' or 'step down' has nothing to do with the way its windings are connected, so it could be wye-delta or delta-wye.
What is Dy transformer step up or step down?
Theoretically, a delta-wye transformer can step up or step down. In Europe, tertiary distribution transformers are step-down delta-wye transformers, so that the secondary side offers a three-phase, four-wire, system offering 400 V line-to-line and 230 V line-to-neutral.

Can you hook up a 250 volt 2.5 amp plug to a 1500 watt transformer?
What has to be taken into account is what the primary and secondary voltages of the transformer are. The second thing to consider is whether the transformer is a step up or step down transformer. Just putting 250 volts on a transformer could burn the windings if the transformer is not the correct voltage.
If I hook up an electrical device that requires 100V 500W with a transformer that outputs 110V 500W will this cause a problem?
No. But I am interested to know what the primary voltage to the transformer is.
How do you determine a wye delta timer is good?
A wye delta timer is used to change the wye connection to the delta connection. The timer should have enough of a setting to allow the wye motor speed to get up to full RPM on that winding. It then times out and changes to the delta run winding. Check the voltage on the "hot" terminal of the timer to make sure that you have control voltage to that point. If the delta magnetic does not pull in check for voltage on the mags coil. If the voltage is present, then the mags coil is under suspicion. Do a continuity test on the coil. When the timer times out the control voltage should appear on the other side of the timers contact. If the timer has a "C form" contact make sure that the coil wire in on the correct screw. The "hot" control wire to common terminal and coil wire to the N.O. terminal.
How do you choose vector group is voltag step up transformer?
A vector group table lists the 'phase shift' or 'angular displacement' for all combinations of three-phase transformer connections. In order to parallel three-phase transformers, their angular displacements (amongst other things) must be the same.'Phase shift' or 'angular displacement', is defined as 'the angle by which the secondary line-to-line voltage lags the primary line-to-line voltage'.Angular displacement depends on the type of transformer connection. The most common are:delta/delta results in an angular displacement of 0o or 180owye/wye results in an angular displacement of 0o or 180odelta/wye results in an angular displacement of 30o or 210owye/delta results in an angular displacement of 0o or 180oIn a Vector Group table, though, the angular displacement is normally expressed in multiples of 30o -e.g. '11', which means 11x 30o, or 330o.From the above data, it would be impossible to parallel, for example, a delta/delta transformer with a delta/wye transformer.BS 171 lists twelve main connections, arranged in four main groups according to their angular displacements. A connected designated, for example, 41 Dy 11, shows:4 -the fourth main group1 -the first connection within that groupD -HV connection is connected in deltay -indicates LV connection is in wye11 -indicates an angular displacement of (11x30o)= 330o.
How do you hook up in-ceiling speakers?
If you have standard ceiling speakers (with no transformer), you hook up the speaker wiring, Black to the left terminal, and Red to the right terminal. If you have 70V commercial ceiling speakers (with a transformer), you bypass the transformer by either just using the Black and Red wires off of the transformer, or bypass the transformer by hooking the Black wire to the left terminal, and the Red wire to the right terminal. If you have a 70V commercial speaker system (uses transformers on speakers and a 70V PA amplifier), strip the ends of the appropriate wires you are going to hook up to your 70V system. Do not strip the ends of the other wires you aren't going to be using. Hope this helps! Thanks!
What is the function of a grounding transformer in a dc electric locomotive and what would make it heat up?
A grounding transformer provides a place to connect the distribution system ground where a delta system provides the AC supply.
