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

DGCT-SThe Electromagnetic Voltage Transformer Ratio and Polarity Tester, also known as the Electromagnetic Transformer Ratio Tester and Electromagnetic Transformer Polarity Tester, is a specialized transformer ratio and polarity tester for on-site ratio check tests during transformer handover and after winding replacement. The Electromagnetic Voltage Transformer Ratio and Polarity 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" mandates on-site ratio check and testing after transformer handover and replacement of winding.

       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 current transformers becomes increasingly larger, reaching tens of thousands of amperes.;It is already challenging to increase the current to hundreds of amperes on-site, and it is nearly impossible to reach thousands or tens of thousands of amperes. Moreover, due to their large size and weight, which can be hundreds of kilograms or even tons, on-site use becomes even more difficult. If the small current method is employed, the influence of the current transformer's magnetic sensitivity, linearity, impedance, and leakage reactance can cause a significant increase in the transformer's error, 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 increasingly an 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 with the application of the latest research theories and findings, tailored to meet on-site operational requirements.
