Electromagnetic Voltage Transformer Ratio and Polarity Tester, Electromagnetic Transformer Ratio Tester, Electromagnetic Transformer Polarity Tester

DGCT-SThe Electromagnetic Voltage Transformer Ratio and Polarization Tester, also known as the Electromagnetic Transformer Ratio Tester and Electromagnetic Transformer Polarization Tester, is a specialized transformer ratio and polarization testing instrument used for on-site ratio check tests during transformer handover and after winding replacement. The Electromagnetic Voltage Transformer Ratio and Polarization Tester supports the following standards:GB/T20840.5-2013、JB/T5356-199。

According toJJG313-94"Current Transformer for Measurement"JJG313-93The "Voltage Transformer for Measurement" requires that on-site ratio testing must be conducted during transformer handover and after the replacement of winding coils.

       The standard method for checking the ratio of conventional transformers is the current method, which, in principle, is an easily understandable and feasible inspection method. However, as the system capacity increases, the primary current of the current transformer becomes increasingly large, reaching tens of thousands of amperes.;Increasing the current to several hundred amperes is already challenging; reaching thousands or tens of thousands of amperes is nearly impossible. Moreover, due to their large size and weight, which can be several hundred kilograms or even tons, on-site use is even more difficult. Using the small current method would lead to a significant increase in current transformer errors due to the influence of magnetic sensitivity, linearity, impedance, and leakage reactance, thereby rendering the ratio check meaningless.

       The electromagnetic voltage transformer ratio polarity tester is compact, lightweight, with a wide measurement range, and easy to carry, making it an increasingly essential tool for transformer testing work, particularly suitable for on-site current transformer ratio testing.DGCT-S The Electromagnetic Voltage Transformer Ratio and Polarity Tester is a summary of domestic and international transformer characteristics by our company.,Developed using the latest research theories and findings, in alignment with on-site application requirements.
