|
Routine Test: |
|
 |
|
Resistance measurement at ambient temp: |
|
|
|
This test is carried out for
I. I2R losses calculation
II. Temp. rise calculation. |
|
|
|
Opening Circuits tests : |
|
|
|
This test is carried out for measurement of no load losses by measuring no load voltage and no load current. |
|
|
|
Vector group test : |
|
|
|
This test is carried out to ensure various combination of transformers I/Ps and O/Ps. This is also useful to check synchronization of two transformers as and when require. |
|
|
|
Megger Test : |
|
|
|
This test is carried out to check insulation resistance between primary & body, secondary & body, primary winding & secondary winding. This is also to carry out for measurement of insulation between core & stud assembly. |
|
|
|
H.V. Test : |
|
|
|
This is to insulation level between various parts of the transformer i.e. primary wdg and sec. wdg , Prim.wdg & body, sec.wdg & body. |
|
| B. |
|
Type Test: |
|
|
|
Heat Run Test : |
|
|
|
In this test one has to check the temp rise winding. |
