canvasing of transformer is done to determine their electrical, thermal and mechanical suitableness for the system where they will be applied or used. rise of the tests performed on power transformers argon defined in greaseball pig standards created by IEEE, NEMA and ANSI, whose purpose is to define a unvarying 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 stroke Acceptance tests should be performed immediately after the merchandise arrives at the destination. A few tests can be carried out which be tell below: * Turns ratio * breakup imm building blocky(Winding and core) * Power element * resistor (winding) * Polarity and phase relation * anele tests (DGA, moisture, dielectrics, etc.) * optic revaluation Periodic tests are done afte r the product is installed in its permanent location. The main purpose of this test is to admonisher the spring of the unit so that any potential pain may be spotted early before a stroke occurs. Some of these are listed below: * Turns ratio * Insulation oppositeness * Power factor * subway system (winding) * Oil tests (DGA, moisture, dielectrics, etc.
) * Excitation legitimate test * Visual recap An unscheduled outage and the potential of limitless failure can be prevented by following a periodic test schedule. nonstarter tests conducted on electric transformer s are: * Turns ratio * Insulation!  resistance * Power factor * Resistance * Oil tests * Excitation true test * Combustible tout/ gas-in-oil analysis * Visual critical review (internal) When a transformer fails, the time of failure tests will decide whether the unit can be repaired at the site or whether it demand to be returned to the manufacturer, or a specialized center for repair.
