Three Phase Transformers have three windings. If connected in Delta, it will have R Y B phase winding, voltage between RY, YB and BR. Phase voltage and line voltage are same.
If connected in Star, there will be a neutral as well with RYB. Line voltage and Phase voltage are different. Line voltage = 1.73 x Phase voltage.
What else can I help you with?
The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
What is the basic Difference between ferrite core and normal transformer?
i think Transformer operates AC and ferrite core operates in DC
How you using ref relay in transformer?
an REF relay (restricted earth fault) is used to provide ground fault protection for a transformer. Its' operation is limited by CTs starred towards the transformer (usually on the transformer bushings or in breakers used to isolate the transformer), so it will only operate for transformer related faults. Because of this, it can be set to operate very quickly.
What is advantages-of-parallel operation of transformer?
It enables an existing transformer to be upgraded to meet an increase in load, without having to remove that transformer and replace it with a 'larger' (expressed in volt amperes) one. It provides an useful way of using up a stock of smaller transformers.
The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
Why series operation of transformer is not prefered?
current increase in series operatio and transformer will b damaged
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
What is importance of vector group of transformer?
The vector group of a transformer is important for determining the phase relationship and polarity of the transformer windings. It helps ensure proper operation and connection of the transformer in the electrical system. Additionally, the vector group is essential for parallel operation of transformer units to avoid phase shifts and ensure synchronization.
What is the operation of a transformer?
A transformer is a static device which is used to step up or step down the voltage in a powered circuit.
Why do you get a typical sound when the transformer is put into operation?
vibration of the transformer's laminated core in response to the AC magnetic field.
What the effect of switch on the no load transformer?
specially for high voltage operation
What are the condition for transformer parallel operation?
CONDITIONS REQUIRED FOR TRANSFORMER PARALLEL operation are.. 1. Voltage turn ratio. 2. phase sequence 3. Impedence should be same 4. polarity Hitesh
What are the basic cost of power transformer?
I have a project now, a 6 MVA 13.8KV/6.6KV transformer costs about $16,000.
What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
Operation of a transformer?
Transforming a signal without changing its frequency.(amplitude can be changed)
How do you determine the proper cable for 240V 3phase 15hp induction motor for a distance of 1000 ft?
This wouldn't be on a farm would it? 1000' line would need it's own utility pole, and transformer.
