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. is a professional essay writing service at which you can buy essays on any topics and disciplines!
