What is the kw of 100kva transformer and how you calculate?
The kW rating of a transformer can be calculated by multiplying the kVA rating by the power factor. For example, if the power factor is 0.8, then the kW rating of a 100 kVA transformer would be 80 kW. You can also use the formula: kW = kVA x power factor.
What is the breakdown voltages of 100KVA transformer bushing and arcing horns?
The question isn't correct, you have to define the voltage level not the power rating.
What is ELSP?
An ELSP is a current limiting fuse used in series with the primary fuse of a transformer.
Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
How many amps can a 100 KVA transformer carry?
A 100kVA transformer is rated for...100kVA. That is its' power rating, and it is based off the current that is flowing through the transformer (the I^2*R losses are the limiting factor). This can be 80kW and 60 kVARs, or 100kW and 0 kVARs, or 100kVARs, or anywhere inbetween.Another AnswerThe 'power' rating of a transformer is the product of its secondary voltage and its secondary current, expressed in volt amperes or multiples thereof. It's not expressed in watts, because to know the 'true power' of the transformer, the manufacturer will need to know the power factor of the load, and that could vary considerably. Incidentally, the symbol for kilovolt ampere is 'kV.A', not 'kVa'.
What position in the circuit is a fuse placed to protect a transformer?
In series to every phase winding of transformer.
What size fuse do you use on 800kva transformer?
For an 800 kVA transformer, the size of the fuse depends on the primary and secondary voltage levels. A common rule of thumb is to use a fuse rating of about 125% of the transformer's full-load current. For an 800 kVA transformer at a standard voltage of 480V, this typically results in a fuse size of around 1,200 to 1,500 Amps, but it's essential to consult the manufacturer's specifications and consider local regulations for precise sizing. Always ensure that the fuse is selected based on both the transformer and application requirements.
What is the fuse rating for 5MVA transformer?
50 amp
Does the fuse on the primary side of a transformer protect the secondary side?
Yes, but it's usual to have fuses on both sides of the transformer.
Why kva rating of transformer is always multiple of 11?
It's not - I have seen 50kVA, 100kVA,...15000kVA, 36000kV, 180000kVA to name a few examples. Near where I live, I don't believe there are more than a few transformers rated in multiples of 11 as you state.
Where is the built in thermal fuse located on a power supply transformer?
the INside
What can you do as preventative maintenance for a power pole transformer so that the mineral oil does not boil?
Lower the rating of the primary fuse feeding the transformer.
