TESTING AND QUALITY ASSURANCE tải catelogue

In oder to ensure product quality and satisfy customers’ demands, THIBIDI has invested a state-of-the art test room with modern instrument. This test room (code: VILAS 054) meets TCVN ISO/IEC 17025:2005 standard and has been aproved by General Department of Standard and Measurement of Vietnam.

In oder to ensure product quality and satisfy customers’ demands, THIBIDI has invested a state-of-the art test room with modern instrument. This test room (code: VILAS 054) meets TCVN ISO/IEC 17025:2005 standard and has been aproved by General Department of Standard and Measurement of Vietnam.

    All transformers are tested according to IEC-60076 standard at this test room. Normally we do two kinds of testing: routine test and type test. Routine test is carried out on each transformer.

       The routine test consists of:

         * Ratio test.

* Polarity and phase relation (Vector             group) test.

         * Resistance Measurement of all windings.

         * No load loss and no load current test.

         * Impedance voltage and load loss test.

         * Insulation resistances test.

         * Power frequency voltage withstand test.

Type test is carried out on a transformer which is representative of other transformers.

        The type test consists of:

         * Temperature rise test.                                      

         * Lightning impulse test.                        

         * Short-circuit test.

         * Sound level test.

Besides THIBIDI’s laboratory will test transformer according to other standards on customers’ request.
