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,
