Testing Laboratory & Quality Assurance
Tests at Elmaksan Transformer Test Laboratory are carried out in accordance with TS EN, IEC and IEEE standards and provide quality assurance at the highest level.
-
Our lightning impulse system can measure at 1200 kJ and 1200 kV levels. Our system has been calibrated by international organizations and TÜBİTAK UME.
-
The newest and best model test device is used for our partial discharge test system. (MPD 600, OMICRON)
-
There are 45 devices in our laboratory and their calibrations are carried out in accredited calibration laboratories.
-
Our loss measurement system has Siemens Software and is fully automatic.
-
In order to prevent human error, the test data measured in our test system is automatically recorded and all test data is instantly tracked in the system.
Routine Tests
-
Measurement of winding resistance
-
Verification of voltage ratio and vector group (polarity check)
-
Measurement of short-circuit impedance and load loss
-
Measurement of no-load loss and no-load current
-
Induced AC overvoltage withstand test
-
Applied AC voltage withstand test (separate source AC withstand test)
-

Special Tests
-
Oil breakdown voltage (dielectric strength) test
-
Measurement of dissipation factor ($\tan \delta$ / Doble test)
-
Paint thickness measurement
Type Tests
-
Temperature rise test
-
Full-wave lightning impulse test
