USE FOR 3 PHASE SUPPLY REQUIREMENT BUT WITH ENGINEERING ECONOMICS BACKGROUND. FOR EXAMPLE YOUR REQUIREMENT IS ONLY 500 KVA AT THE MOMENT BUT HAVE PLANS FOR EXPANSION IN THE FUTURE THEN YOU HAVE TO INVEST ONLY FOR 2 NOS. OF 333 KVA TRANSFORMER CONNECTED LIKE REMOVING ONE LEG OF DELTA SHAPE. YOU WILL HAVE A CAPACITY OF 3 X 333KVA DIVIDED BY SQUARE ROOT OF 3 = 577 KVA(57.7% OF CLOSED DELTA) WHICH SATISFY YOUR PRESENT REQUIREMENT. IN THE TIME YOU WANT TO EXPAND LOAD - JUST ADD ONE UNIT 333 KVA TO BE A CLOSED DELTA IT WILL GIVE YOU 999=1000KVA CAPACITY(42.3% MORE).

What is the difference between an open delta and an open wye connection?
An open delta connection is a delta connection with one phase removed, but still supplied with three line conductors. An open wye is a wye connection with one phase removed, supplying a three line conductors and a neutral conductor. An open-delta/open-wye is a method of providing a reduced-load three-phase supply using just two single-phase transformers, rather than the preferred method of using three single-phase transformers.
What is the percent efficiency of an open delta connected transformer?
67%
Can you hook up a delta to delta transformer to be a delta to wye transformer?
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.
If one transformer of a delta transformer bank fails the bank can be reconnected open delta and operate at reduced efficiency?
yes open all fuses close the primary neutral tap,remove secondary leads off of bad traansformer,tell customer to reduce his load until bad transformer can be replced.
How far is delta arietis the star from the earth?
There is no object that is simply called "delta". On the other hand, there are several that have delta as part of their name, usually followed by the constellation, e.g. delta orionis, delta canis maioris, etc.

What is an unavailable seat on Delta Airlines?

Delta airlines has many jobs. One can get a job with Delta airlines by going to an employment center where they help one find and apply to all available jobs.
How can water change the appearance of a river delta?
It breaks open rocks (erosion)
Why open delta voltage is zero in normal condition?
Assume a Delta connection (triangle connection) is closed. then each corner of the triangle, as one point, is considered 0 Volt. Now if you open that point, still you have 0 Volt.
What is open delta connection explain with circuit diagrams?
If one of the transformer is unable to operate, then the supply used to load can be continued with the remaining tow transformers at the cost of reduced efficiency. This is known as open delta connection or V-V connection.
Delta and theta activity increase when eyes are open?
Delta waves are associated with deep sleep and indicate relaxation. Theta waves are linked to daydreaming, creativity, and light meditation. The increase in delta and theta activity when the eyes are open could be due to the brain entering a state of relaxation or daydreaming while maintaining alertness.
