The KVA rating of a transformer is based on how much heat the transformer can dissipate. The BIL rating is based on how well the windings are insulated. There are other "ratings" as well. Rough calculations can be done, but tests are generally performed to prove the calculations (transformer designers will design on the conservative side to insure the transformer meets specification). These type of calculations are best done by a computer. You will struggle to determine the hot spot max temperature rise in a transformer by hand.

What is the maximum power generated in India?

Advantages of autotransformer?
the power can flow either way through autotransformer (345/120 kV) ?
What are the different generating voltages?
it varies from power station to power station in vtps we have 15.75 kv
Is kv cbt a good school?
No k.v. Is not a good school.chemistry sir hardly comes to our class.
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.
What is the line current in HT line of 11 KV?
it is depends on the rating of distribution transformer,e.g if there is 100 kva, then it will take 5.25amp.
How much min BDV of oil in transformer is required when charged it first time in 11kv 66kv and 132 kv of transformer?
The minimum Breakdown Voltage (BDV) of transformer oil required typically varies based on the voltage level of the transformer. For 11 kV transformers, a minimum BDV of around 30 kV is usually acceptable. For 66 kV transformers, a BDV of approximately 50 kV is often required, while for 132 kV transformers, it should be at least 60 kV or higher. Ensuring adequate BDV is crucial for the insulation performance and reliability of the transformer.
Why is the primary of a transformer 11kv?
It isn't necessarily the case. In the UK electricity distribution system, you have 33/11-kV step-down tranformers (where 11 kV is the secondary side) or 11-kV/400-230-V step-up transformers (where 11 kV is the primary side).
What is the maximum capacity of 11kv transformer?
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
How transformer converts mva to kv?
Transformer does not convert MVA to KV. MVA is unit of power, where as KV is unit of Voltage. Transformer converts voltgae. Step up or Step down.
What is the minimum resistance when megohming 13.2kv transformer?
A megger would not be suitable for testing insulation resistance of a 13.2-kV transformer, as the transformer's voltage rating is significantly higher than the output voltage from a megger.
Its possible to convert 11 kv to 5v by potential transformer?
If you have to ask this question, you shouldn't be dealing with 11,000V
What is the conversion of KV to KVA?
These are two incompatible units. Ignoring the kilo- prefix (1000), we have V (Volts) and VA (Volt-Amps). VA is a rating of power, typically on transformers and related equipment. So while you cannot _convert_ from KV to KVA, you can calculate one from the other. For example, a 240V transformer rated to supply 100A of current would be a (240*100 = 24000) 24kVA transformer. Power = Volts * Amps.
What types of transformers used in 220 kv double bus switch yard?
We use double rating transformer, in this we have two type of cooling . ONAN & ONAF, According to cooling we have two rating.
What is the function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
What is the different between 6.6 kv 160 a 11 kv 160 a fuses?
6.6 kV and 11 kV refer to the voltage rating of the fuse. 160A refers to the current rating. The 6.6 kV fuse is safe to use in a circuit with a voltage up to 6.6 kV and no greater. The 11 kV fuse is safe to use in a circuit with a voltage up to 11 kV.
