Testing of Transformer

trial runing of transformer is done to determine their electrical, thermal and mechanical suitability for the system where they will be applied or used. dear(p) of the tests performed on power transformers argon defined in dago pig standards created by IEEE, NEMA and ANSI, whose purpose is to define a analogous 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 calamity Acceptance tests should be performed immediately after the crossing arrives at the destination. A few tests can be carried out which argon tell below: * Turns ratio * insularity imm unity(Winding and core) * Power component * resistor (winding) * Polarity and phase relation * fossil oil tests (DGA, moisture, dielectrics, etc.) * optical revaluation Periodic tests are done after the product is installed in its permanent location. The main purpose of this test is to manage the spring of the unit so that any potential knock over may be spotted early before a stroke occurs. Some of these are listed below: * Turns ratio * Insulation granting immunity  * Power factor * subway system (winding) * Oil tests (DGA, moisture, dielectrics, etc.

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