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 check tests during transformer handover and after the replacement of windings. 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" requires on-site ratio check and testing to be conducted when transformers are connected and after the replacement of winding units.

       The conventional method for checking transformer ratios of standard current 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 transformers becomes increasingly larger, sometimes 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, with a large volume and weight of several hundred kilograms or even tons, on-site use becomes even more difficult. Using the small current method would significantly increase the error of the current transformer due to its magnetic sensitivity, linearity, impedance, and leakage reactance, thereby losing the significance of ratio checking.

       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, suitable for on-site current transformer ratio testing instruments.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 cutting-edge research theories and findings, tailored to meet on-site usage requirements.
