It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.

What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What is the maximum value power capacity of dry type transformer?
What's the maximum value power capacity of dry type
Can a 400-110v step-down transformer be reverse-connected to the secondary of an 11kv-110v transformer to obtain a 400v 3-phase and neutral output from an 11kv mains panel to make an AMF mains input?
Possibly... but only a trained electrical technician would be licensed to do that kind of work!
Why differential relay is not used for 11kv transformers?
It depends what you mean by an '11-kV transformer'; do you mean a primary transformer (33/11-kV transformer) or a distribution transformer (11-kV/400-230-V transformer). Differential protection IS offered on primary transformers.
How do you find capacity of transformer?
If the load is single equipment, calculating the capacity of the generator or transformer is fairly straight forward. If the load is mix of various several different equipment it would be more complicated to arrive at transformer / Generator capacity. Complexity increases if you have to estimate some future unknown loads. The rating of the generator or transformer should be such that it is loaded optimally, average being say 80 to 95 %. Since maximum efficiency of generator or transformer generally occur at these range. Also this ensures that it is not overloaded continuously and there is room for occasional short time full load too. You need to check the data sheet of the transformer or generator for more correct information. One need to know the maximum load or peak load, average load and diversity factor and load factor. These values drive the decision on the rating of the transformer or Generator.

What is the maximum capacity of power transformer at 220kV voltage?
800 MVA
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
What is current choking in transformers?
The "current choking" means that the maximum capacity of a transformer is not being utilized. To prevent it from ever reaching its maximum capacity a lower value of over current protection or fuse is installed. The purpose is to use larger capacity transformer available but using smaller distribution and cables just sufficient for the application to lower the installation cost.

What is the maximum transformer rating for distribution transformer?
100MVA
When is the efficiency maximum in a transformer?
the efficiency is maximum in a transformer when no load loss is equal to load loss.

Why is the rating of transformer is like 11kv 33kv 66kv?
Because the tranformer calculation for ratings is calculated with the formfactor which is 1.11 constant. Regards Mithin kudva
What is maximum efficiency condition in distribution transformer?
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss
