250 kVA OIL TYPE DISTRIBUTION TRANSFORMER Measuring winding resistances Measurinq rotation ratios Inspecting polarity or connection group Measuring short circuit and load losses Measuring idle losses and current Induced voltage test Applied voltage test Measuring insulation resistances Transformers, for which mounting, drying and oil filling works are completed, are subjected to below mentioned routine and typical tests as specified by TS 267 standard. Oil breakdown stress control Loss gap (tq) measurement (DOUBLE test) Measuring painting thickness Temperature increase (heating test) Measuring of audible noise level Boiler lifetime test (For Hermetic Transformers) Mechanical strength test against short circuits This test is conducted in CESI/ITALIA, IPH/GERMANY test laboratories.) Except for the mechanical strength test against short circuits, all typical tests are conducted in the laboratories of our company,
