Transformer Test Equipment
DV Power test instruments perform various diagnostic tests on power and instrument transformers. Even more, a unique feature is a condition assessment of on-load tap changers. Performing a transformer test before their breakage can be crucial.Test instruments are portable and enclosed in durable metal cases. Also, the 19” rack-mounted version suitable for factories is available as well.Applications supported by DV Power transformer test equipment include:Winding resistance measurement (IEC 60076-1)Analysis of on-load tap changers (IEC 60214-1)Heat run test (IEC 60076-2)Automatic transformer demagnetizationTurns ratio measurement of power and instrument transformers (IEC 60076-1)Excitation current measurementPhase angle measurementTransformer vector group detectionDemagnetization status verificationAll of the above-mentioned measurements are performed with the highest accuracy.The advanced DV-Win PC software collects both numerical and graphical results. As a result of that, these features provide an easier and more efficient analysis. After the test, DV-Win software generates a test report with a single click. Furthermore, a user can easily customize the test report and save it in different formats, such as XLS or PDF.Finally, the analysis of on-load tap changers is performed by the new method called dynamic resistance measurement (DRM). This is a non-intrusive method. Therefore, it allows detecting problems in on-load tap changers without disassembling them.

PPS Clamp Transformer
PPS2 provides power supply to the PD detectors installed on HV cable when low voltage AC power is not available. The PPS2 takes the required power directly from the High Voltage power line under monitoring by means of units clamped on the HV power cable(s).PPS2 is designed to withstand High Voltage line failure events such as temporary overload and short circuit conditions. An internal detection and self limiting circuitry guarantees that PPS2 and the connected equipment survives in case of such events.
