Transformer Testing methods ?
Transformer Test?
Tests on the transformers are carried for verifying the capabilities of transformer to withstand Thermal stresses, Dielectric stresses, short circuit electro-dynamic stresses and environmental stresses.
Routine test?
These are carried out on every transformers before dispatch to ensure that it is in accordance with the specifications.Some of the tests come under routine test includ?
Measurement of the winding resistance
Verifying the polarity of the windings
Measurement of load losses and the impedance voltages
Measurement of no load losses and no load no load current.
Electrical tests at the power frequency
Type Test?
Type tests are performed on the first transformer of one type and are intended to check the design characteristics. It is presumed that every transformer would also comply with the type test, since its design is identical.
Temperature rise test
Tests of ability to withstand full wave impulse
Tests for switching impulse withstand
Noise level test
Special Tes?
Special tests are conducted in the presence of the purchaser or his representatives as specified in the tender
Partial discharge test
Checking the level of Radio interference voltage
Vibration test
Test on ability to withstand Short -circuit current
Measurement of Noise level
