The GDGK-307 high-voltage switch characteristic tester evaluates the synchronization of circuit breakers through multi-channel testing, accurate characteristic curves and analysis calculation functions, high-speed data acquisition and analysis processing capabilities, etc.In the power system, the sy

Yesterday we just shipped one set GDBC-901 Transformer turns ratio ttr tester to our customer.This TTR Tester is suitable for testing both single phase and three phase transformer.The max test voltage is 80V,ratio measurement range is 1-10000. You can also connect PC to download the test results.Wel

What's the principle of low-frequency method for measuring the excitation characteristics of current transformers?Excitation characteristic test is the most commonly used and effective method for detecting the performance of protective current transformers.The composite error of current transformers
