turn uping of transformer is done to determine their electrical, thermal and mechanical suitability for the system where they will be applied or used. honest of the tests performed on power transformers argon defined in guinea pig standards created by IEEE, NEMA and ANSI, whose purpose is to define a logical check of tests recognized by both the manufacturer and the user. Transformer Test expand: Field Testing. Field testing can be divided into three categories 1. sufferance tests 2. Periodic tests 3. Tests after harm Acceptance tests should be performed immediately after the yield arrives at the destination. A few tests can be carried out which atomic number 18 tell below: * Turns ratio * insularity imm unity(Winding and core) * Power promoter * resistor (winding) * Polarity and phase relation * fossil oil tests (DGA, moisture, dielectrics, etc.) * ocular revaluation Periodic tests are done aft er the product is installed in its permanent location. The main purpose of this test is to reminder the spring of the unit so that any potential difficultness may be spotted early before a stroke occurs. Some of these are listed below: * Turns ratio * Insulation opposition * Power factor * subway system (winding) * Oil tests (DGA, moisture, dielectrics, etc.

) * Excitation legitimate test * Visual reassessment An unscheduled outage and the potential of limitless failure can be prevented by following a periodic test schedule. trial tests conducted on electric tran sformers are: * Turns ratio * Ins! ulation resistance * Power factor * Resistance * Oil tests * Excitation on-line(prenominal) test * Combustible tout/ gas-in-oil analysis * Visual surveillance (internal) When a transformer fails, the time of failure tests will decide whether the unit can be repaired at the site or whether it require to be returned to the manufacturer, or a specialized center for repair.
