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 testing instrument used for on-site ratio checks and 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 that a field ratio check and test must be conducted upon transformer handover and after the replacement of the winding.

       The conventional method for checking the ratio of standard transformers is the current method, which, in principle, is an easily understandable and feasible check. However, as the system capacity increases, the primary current of the current transformer becomes increasingly large, sometimes reaching tens of thousands of amperes.;It's already challenging to increase the current to several hundred amperes on-site, let alone thousands or tens of thousands of amperes, considering the large size and weight, which can reach hundreds of kilograms or even tons. On-site use becomes even more difficult. If the small current method is employed, the magnetic sensitivity, linearity, impedance, and leakage reactance of the current transformer can significantly increase the transformer ratio error, rendering the ratio check meaningless.

       The electromagnetic voltage transformer ratio polarity tester boasts a compact size, lightweight design, wide measurement range, and ease of portability, 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 Test Instrument is a summary of domestic and international transformer characteristics by our company.,Developed using the latest research theories and findings, in conjunction with on-site usage requirements.
