Is it safe to use a step down transformer rated 16 Volts and 40 VAC in place of required transformer rated 24 Volts and 40 VAC?
Transformers that operate specific devices should be matched to the specific voltage on the device that the manufacturer specifies.
Why transformer not rotating?
transformer is not rotating bcoz for rotating rotating magnetic field is required which is produced only when the current is passed through the windings which are displaced physically by 120degrees and phase difference of 120 degrees where as in transformer there is no phsical displacement of 120degrees hence transformer cannot rotate.
How do you check a transformer for ac house unit?
Check that the input and output voltages are as required. Check that the transformer is big enough for the current required for the unit you have.
What is the KVA rating required of the testing transformer?
Depends on the kva rating of the devices to be tested using a transformer.
Why required oil inside the transformer?
To cool and to insulate the transformer. Transformer oil has a higher specific heat capacity than air, so it is more efficient at removing energy through heat transfer, and limiting the windiings' temperature rise. Transformer oil has a much greater dielectric strength than air, which means that components at different potentials can be placed closer together, so the overall volume of the transformer can be made smaller, giving it a smaller 'footprint'.
What are the purposes of performing no load test for the transformer?
These two tests are performed on a transformer to determine (i) equivalent circuit of transformer(ii)voltage regulation of transformer(iii) efficiency of transformer. The power required for theseOpen Circuit test and Short Circuit test on transformeris equal to the power loss occurring in the transformer.
How much oil in liters required for sealed type 95 KV 1200mA - TR Set transformer?
That depends on the model of the transformer. I have seen transformers that required 7500 liters and some that needed 2,5 liters.
What are the components required for charging mobile using sound energy or noise?
transformer
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
How do you decide transformer oil filteration required?
When the water content in the oil in the Oil rises up to or more than 2% than it is needed to replace the transformer oil or filter it.
Why should the secondary of a voltage transformer not be short circuited?
A voltage transformer takes a primary voltage and steps it down to a smaller secondary voltage. This type of transformer will attempt to keep the secondary voltage at a specific ratio of the primary voltage. If you short it, massive current flow in the secondary is required to do this. For a similar reason a CT should never be open circuited - because it attempts to push a specific ratio of primary current through the secondary. If you open circuit the secondary, it takes a massive voltage on the secondary to accomplish this.
What is meant by LOT in CRT monitors?
its a line output transformer, also known as a flyback transformer, it provides the high votage required to run the tube. http://en.wikipedia.org/wiki/Flyback_transformer
