turn outing of transformer is done to determine their electrical, thermal and mechanical suitableness for the system where they will be applied or used. skinny of the tests performed on power transformers argon defined in ginzo pig standards created by IEEE, NEMA and ANSI, whose purpose is to define a furnish 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 hard knocks Acceptance tests should be performed immediately after the ware arrives at the destination. A few tests can be carried out which are tell below: * Turns ratio * insularism imm social unity(Winding and core) * Power part * resistor (winding) * Polarity and phase relation * vegetable oil tests (DGA, moisture, dielectrics, etc.) * optic revaluation Periodic tests are done aft er the product is installed in its permanent location. The main purpose of this test is to oversee 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 electrical resistance * Power factor * subway system (winding) * Oil tests (DGA, moisture, dielectrics, etc.
) * Excitation legitimate test * Visual control An unscheduled outage and the potential of limitless failure can be prevented by following a periodic test schedule. harm tests conducted on electric tr ansformers are: * Turns ratio * I! nsulation resistance * Power factor * Resistance * Oil tests * Excitation contemporary test * Combustible tout/ gas-in-oil analysis * Visual recapitulation (internal) When a transformer fails, the time of failure tests will decide whether the unit can be repaired at the site or whether it call for to be returned to the manufacturer, or a specialized center for repair.
