Moisture causes problems in Transformers, and is not desired. Pulling a vacuum causes the moister in the oil impregnated paper and nonmetallic supports to evaporate, and as the vacuum is held, this moister can be removed.
What else can I help you with?
Is wattmeter reading under no load test is equal to iron loss of the transformer?
Yes; that is the principle used in no-load tests on transformers. The current in the copper windings is zero on the secondary and low on the primary, so the copper loss is negligible.
What are the advantages of automatic load sharing of transformers?
advantages for automatic load sharing of transformer with protective analysis
What is the RMU How you test the rmu?
a type of switchgear used to connect distribution transformers
Can a Auto transformer have more load losses than its no load losses?
Power transformers have both no load and full load losses. The key is copper wiring, as copper varies with the square inches of the secondary and primary currents.
What is a load break elbow?
Designed for industrial facilities, these fully shielded and insulated plug-in terminations connect underground cables to transformers, switchgears and junctions with load-break bushings.
What do you mean by test?
Its a test conducted on two identical 1- phase Transformers to determine the efficiency at different loads (without actually connecting any load).
What do you mean by sumpners test?
Its a test conducted on two identical 1- phase transformers to determine the efficiency at different loads (without actually connecting any load).

What is paralleling of transaformers?
Paralleling transformers will increase the effective capacity available to the load. There are important requirements before transformers can be paralleled, so it's simply not the case of connecting any two transformers in parallel.
How does load sharing in transformers happen?
For parallel operation of let's say two transformers, following limiting conditions must be met. 1- The turn ratios must be same. 2- The percentage impedance must match. 3- The X/R ratios must be same. The load sharing is done according to the kVA ratings and %Z of the transformers. The formula is as under: load taken by TF1 = ((kVA1/%Z1)/((kVA1/%Z1)+(kVA2/%Z2)))*total load Similarly, load taken by TF2 = ((kVA2/%Z2)/((kVA1/%Z1)+(kVA2/%Z2)))*total load An example will make the concept easier. For example we have to parallel a 1000kVA TF of 5%Z with another of 1200kVA having 5.5%Z to supplay a load of 800kVA. load taken by TF1= ((1000/5)/((1000/5)+(1200/5.5)))*800= 382.6kVA load taken by TF2= ((1200/5.5)/((1000/5)+(1200/5.5)))*800= 417.4kVA
What is the minimum load have to go for a new transformer?
All transformers have a power rating given in kVA which determine the maximum load that can be connected to that transformer.
What is the initial load in Rockwell hardness test?
The initial load in Rockwell hardness test is 10KGf.
How do you load test a Harley Davidson motorcycle battery?
You can take it to a battery place and they can test it under a load.
Why should dc series motor can be operated for no load and light load?
dc motors can be operated at no load as well as at load condition.But by using the swin burns test the efficiency can be calculated at no load which is more benficial than load test.At industries this swin burns test is used because for load test we have to give separate supply for the load to run.In no load test that power is saved.
What is mean of resistive load?
i think it is high value resistance as it is used in Transformers to get the output voltage.
