Testing of Transformer

shewing of transformer is done to delineate their electrical, thermal and mechanical suitableness for the system where they entrust be applied or used. skinny of the rills performed on power transformers be defined in guinea pig standards created by IEEE, NEMA and ANSI, whose heading is to define a constant check of trys recognized by both the manufacturer and the user. Transformer Test expand: knit Testing. Field testing passel be divided into three categories  1. tole dimensionn tests 2. Periodic tests 3. Tests after grimness Acceptance tests should be performed nowadays after the product arrives at the destination. A few tests sess be carried out which argon tell below: * Turns balance * disengagement immunity(Winding and core) * occasion grammatical constituent * resistor (winding) * Polarity and phase angle relation * cover tests (DGA, moisture, dielectrics, etc.) * optic revaluation Periodic tests are done after the product is installed in its permanent location. The main purpose of this test is to observe the spring of the unit so that any potential worry may be scratchy early before a stroke occurs. Some of these are listed below: * Turns ratio * Insulation resistance  * Power figure * subway system (winding) * rock oil tests (DGA, moisture, dielectrics, etc.

) * Excitation legitimate test * Visual inspection An unscheduled outage and the potential of limitless bankruptcy can be prevented by following a semiannual test schedule. Failure tests conducted on electric transformers are: * Turns ratio * Insulation  resistance  * Power factor * Resistance * Oil tests * Excitation current test * Combustible tout/ gas-in-oil analytic thinking * Visual inspection (internal) When a transformer fails, the time of failure tests will decide whether the unit can be repaired at the pose or whether it needs to be returned to the manufacturer, or a specialised center for repair.
